1.3 Required Personnel

ATTENTION

The transceiver has to be configured by qualified personnel. Installation and operation of the transceiver should be assigned to adequately skilled personnel.

The personnel must be familiar with this Operating Manual.

1.4 Required Power Supply

WARNING

Danger of electric shock!

The transceiver meets the requirements for Safety Class I in accordance with DIN EN 61010-1/IEC 61010-1, e.g. all metal parts that can be touched or accessed without removing the enclosure are connected to the protective ground of the power supply network.

When connecting the instrument to the AC power supply, always use a power cable with thermal connector and a socket with earthing contact.

WARNING


The radio contains a two-pole or neutral-conductor fuse. This means that some parts of the radio will continue to be energized after the fuse has been tripped.

When replacing the fuse, always disconnect the radio from the AC power supply. Do not touch any live parts when performing service and maintenance on the radio while the radio is switched on (by qualified service personnel only).

External DC Power Supply\\External DC power supply "Name".doc

ATTENTION

The external DC power supply should deliver a short-circuit current ofI ≥ 30 A to ensure that the overcurrent protective device functions properly in the event of a malfunction.

Note: To ensure that the radio works properly, it is required to supply an earthing contact.

AC voltage The transceiver operates on an AC voltage.

When the transceiver is connected to the AC line, it automatically sets itself to the correct voltage (AC voltage 115 V/230 V). There is no need to set the voltage manually or change the fuse.

DC voltage The transceiver may also be powered by an external battery (28 V DC). An automatic switchover facility integrated in the radio provides for automatic standby switchover in case primary power fails.

Note: See chapter 2.4 for basic cabling and further information.

Function of the R&S XU 4200 transceiver

The transceiver R&S XU 4200 contains the R&S EU 4250 receiver module and the R&S VU 4250 transmitter module, which is powered by the R&S IN 4240 power supply unit.

Front panel control unit

The front panel control unit A8 with LCD and keyboard A9 make local control of the radio possible on a lab bench or for activities such as installation and maintenance. You can audio-monitor to the demodulated analog voice in the receiver module at any time by using the built-in loudspeaker. The RF signal issued at common antenna X3 is demodulated in the transmitter module and can be audio-monitored at any time via the built-in loudspeaker too. You can control the volume by means of the volume control on the front panel.

The main fan is controlled and monitored by the control unit A8.

USB interface You can configure and make basic settings for the radio via the USB interface on the front panel. In addition you can download software of all firmware components via the USB. The main backplane A6, which connects all modules, contains a USB hub and connects the transceiver's USB interface controller with the front panel control unit A7.

Remote control Remote control is performed as standard via the Ethernet − LAN interface “Ethernet − LAN Remote Control X6” (TX) or “Ethernet − LAN Remote Control X9” (RX) using the powerful R&S remote-control protocol GB2PP.

Power supply The radio can be powered by AC and/or DC voltage. If the AC source fails, the radio automatically switches to the DC source. You can switch the radio on with the switch on the front panel A7.

Display LEDs indicate the current operating state at all times. You can display the operating settings, radio configuration, analog measurement values and status in detail on an eight-row LCD.

Audio interface Receiver module:

On the system side the 600 ohm audio interface “RX Audio Basic X10” is connected to the rear panel and the squelch state can be signalled here via a contact.

Transmitter module:

On the system side the 600 ohm audio interface “TX Audio Basic X5” is connected to the rear panel and the PTT keying is activated. You can flexibly configure the PTT input via service PC and adjust it to the voltage conditions (−48 V, +28 V, optocoupler input) in the system.

Note: Audio interface can also support digital audio nterfaces of E1 and VoIP.

Main and standby function

For redundant system installations with 1:1 switchover, the main and standby radios are connected with each other via hardware contacts. This allows quick switchover without any delay in the event of a failure. In addition, an antenna relay can be connected and controlled.

R&S XU 4200 General Data

6166.5368.02.01 1.6

Extended DSUB interface

Receiver module:

The 15-contact extended DSUB interface “RX Audio Extended X11“ provides discrete digital control contacts as well as the analog output for RSSI received signal strength.

Transmitter module:

The 15-contact extended DSUB interface “TX Audio Extended X7” provides discrete digital control contacts too.

Receive antenna The receive antenna is connected to the BNC input "RX Input X8". The receiver consists of the analog RF board A3 with its VCO/synthesizer and 600 ohm audio interfaces as well as the digital interface module A5 with the main VCXO/clock processing unit, DSP, LAN and USB controller. The received signal is mixed and converted to the first intermediate frequency (IF). The remaining processing is performed digitally, where the various channel spacing 8.33 kHz/25 kHz and modulation schemes AM and ACARS are processed via the software.

Transmit antenna The transmit antenna is connected at to N-connector X3. The transmitter consists of power board A4 with 200 Wpep output stage and analog/digital board A1 with the main VCXO/clock processing unit, VCO/synthesizer, 600 ohm audio interface, DSP, LAN and USB controller. The AM and ACARS modulation signals are processed digitally in the baseband and transformed to output frequency via the I/Q modulator. The output signal of the transmit output stage is coupled out and linearized via the Cartesian I/Q control loop. Modules A4 and A1 are mounted on the high-power heat sink and are cooled by the fan.

Main TCXO The main TCXO on the A6 backplane board serves as the reference for the radio and can be easily adjusted via the USB interface.

3.2.1 Control Interfaces

Control Interfaces\Control interfaces "Radio".doc

Operation Operation can be performed locally on the built-in front panel control unit or remotely via the USB or Ethernet − LAN interface. Operational parameters such as setting the frequency, changing the channel spacing or activating presets can be controlled. In addition, the current status Information and indicators such as GO, ACTIVE, SQ, CARRIER or VSWR can be received from the transceiver and displayed.

Maintenance Maintenance status parameters can be read out via the USB or Ethernet − LAN interfaces, and the built-in front panel control unit. The transceiver delivers the result of the continuous built-in test (CBIT) and the event list, which saves all events with the time information of occurrence.

Maintenance activities can be performed and controlled via the built-in front panel control unit and remotely via the USB or Ethernet − LAN interface. The transceiver provides commands for switching over from main to standby (and vice versa) and for performing a test transmission. In addition, the device can be reset or the real time clock (RTC) can be initialized locally or remotely.

Performance values Performance values can be read out over the built in front panel control unit or over the Ethernet − LAN interface. Parameters such as modulation depth, temperatures, voltages, power levels, receive signal, audio level and VSWR can be measured.

Configuration Configuration of the transceiver can be performed with the Service and Maintenance Tool R&S ZS 4200, which runs on a standard PC or laptop. Connected via service PC, the radio provides easy and fast configuration of the radio basic parameters such as IP address, PTT timeout, power audio-levels and preset pages.

The configuration files can be saved and loaded to the transceiver. The configuration process is very convenient and allows you to quickly configure an entire rack. In case of service, the defective radio can be “cloned” and the parameters loaded to a replacement radio.

Preset loading Up to 200 preset pages can be loaded via the USB or Ethernet − LAN interfaces.

Inventory All hardware and software components can be read out on all the USB or Ethernet − LAN interfaces and are visible on the built-in display.

Software update The R&S DS 4200 software is delivered as a CD ROM and contains all software components, which are automatically loaded to the radio modules via the USB interface. The Service and Maintenance Tool R&S ZS 4200 provides a software download manager, crosschecks the hardware and software and ensures a proper software download.

3.3.2 Meaning of Parameters

Default setting description\Default setting description "Radio".doc

TX Audio Level This parameter refers to the modulation input (connector X5.2/3). With the default setting, the modulation sensitivity is of 0 dBm – which means that at an AF level of 775 mV at this 600 ohm input, the AM transmitter is driven and modulated at 90 % modulation. The input can be configured from −30 dBm to +10 dBm in accordance with the line infrastructure and the incoming signal levels. The sensitivity is greatest at −30 dBm, which means that the full modulation of 90 % modulation is achieved even at a low level.

RX Audio Level This parameter refers to the audio output of the AM receiver (connector X10.2/3). With the default setting of 0 dBm, an effective level of 775 mV is applied at 60 % AM modulation of the current receive signal. The output can be configured from −30 dBm to +10 dBm in accordance with the line infrastructure.

TX Output Power Level Low

Using this parameter, you can define the transmit power between 5 W and 20 W. This value is then adopted with the Low setting (see chapter 3.4.7.2).

TX Output Power Level Normal

Using this parameter, you can define the transmit power between 5 W and 50 W. This value is then adopted with the Normal setting (see chapter 3.4.7.2).

S/N Squelch Threshold

The threshold value for the signal to noise (S/N) ratio can be set for the squelch. If the squelch is activated, the RX audio output is muted until an RF receive signal with a sufficient S/N ratio is applied.

The S/N threshold can be set in a range between 6 dB and 20 dB.

Note: The thresholds are defined for S/N. The corresponding value of SINAD will be 2 dB higher (SINAD 12 dB value corresponds with S/N 10 dB value).

RSSI Squelch Threshold

The RSSI threshold is based on the received signal level at the receiver’s input. The RSSI threshold can be set in a range between 1 μV and 50 μV.

Carrier Override This parameter refers to opening the squelch in presence of a carrier which is higher than –85 dBm, even if other squelch criteria like S+N/N of the audio signal are not met.

Note: If the parameter is enabled and the input level is above –85 dBm, the other squelch settings S/N Squelch Threshold, RSSI Squelch Threshold and S/N RSSI Logical Operation are insignificant.

S/N RSSI Logical Operation

It is possible to combine the S/N-squelch and RSSI-squelch. By default both mechanisms are “OR” conjunct. The squelch opens the audio path if only one condition is fulfilled. In case of the “AND” conjunction both thresholds must be exceeded in order to open the audio path.

Note: For offset reception it is recommended to configure the conjunction type to “OR”.

Note: If the "AND" conjunction type is selected, the squelch attack time can be longer for levels above the RSSI Squelch Threshold than in "OR" conjunction type. If the "OR" conjunction type is selected for input signals below the RSSI Squelch Threshold, the attack time can be longer.

TX AM Modulation Depth

The modulation depth for the AM modulation can be set.

When the automatic level control (see TX Audio ALC parameter) is activated, the set AM modulation is ensured over a dynamic range of ±15 dB at the TX audio level interface (X5.2/3).

Note: The AM modulation should be left at 90 % all the time, since the radio link is best at this value.

TX Audio ALC The automatic level control for the audio modulation can be switched on and off.

When this function is activated, the set AM modulation depth (see TX AM Modulation Depth parameter) is ensured over a dynamic range of ±15 dB at the TX audio level interface (X5.2/3).

Note: If an automatic level control is active in the system external to the radio, then the level control of the radio should be switched off.

RX Audio AGC The automatic gain control in the AM demodulator can be switched on and off. It ensures that the dependency of AF amplitude on modulation depth signal is compensated. In the range from 30 % to 90 % modulation depth, the signal (RX Audio) remains constant.

PTT Timeout A time limit can be set for the transmit time. This prevents the radio from transmitting for an unlimited amount of time if the PTT key is pressed (stuck). With a value of 0 s, the time limit is switched off.

Note: It is recommended to disable the PTT Timeout in the VoIP mode.

PTT Input Configuration

There are three different input configurations for the rear PTT input (connector X5.8/9).

Type I stands for optocoupler input.

Type II should be configured if the system ground (= ground of the PTT key) does not have the same potential as the rack ground. In this case, the PTT circuit is fed via the negative voltage of −48 V in the radio.

With the Rohde & Schwarz standard, a pull-up resistor is switched against the positive voltage of +28 V in the radio.

True Sidetone Transceiver

The built-in receiver demodulates the emitted signal of the transmitter and a true sidetone is provided to the Audio RX output.

Depending on the configuration, the receiver in the housing is muted during transmission. In this case, a true sidetone is not supplied.

Note: Not supported in receivers.

5-Carrier Offset The transmitter allows different frequency offsets to be set. Normally the 2-carrier, 3-carrier and 4-carrier offset with the values of −7.5 kHz / −7.3 kHz / −5 kHz / −2.5 kHz / 0 kHz / +2.5 kHz / +5 kHz / +7.3 kHz / +7.5 kHz are available. In addition, the 5-carrier offset can be selected; this provides −8 kHz / −4 kHz / +4 kHz / +8 kHz in the transmitter.


6166.5368.02.01 3.16

ACARS Data Mode With this parameter the radio can be configured for voice (disabled) or ACARS data operation (enabled) (2400 Bps).

The Voice setting is optimized for voice processing and squelch muting.

The ACARS setting available for receiving ACARS data. In this case a faster RF front-end control is in action. The attack and decay time is in accordance with the ETSI EN 300676 standard.

If the radio is operating in ACARS data mode, only the 25 kHz spacing can be used and the parameters RX Audio AGC and TX Audio ALC must be deactivated.

Select Audio Interface This parameter is used to select the audio interface of the radio. If the Analog Audio is selected, the RX Audio Basic interface X10/TX Audio Basic interface X5 is used. If the E1 is selected, the E1 – Communication Data interface X13 is used. For more information on E1 interface please refer to chapter 3.12 Audio via E1 Interface. If VoIP is selected, audio data will be transmitted via Ethernet by the data interface X6 (RX), X9 (TX) (see chapter 3.15) and TX Audio Basic interface X5. For parallel operation of VoIP and Analog Audio interfaces, please see chapter 3.15.9 Parallel Operation of the Analog and VoIP Audio Interfaces.

RX Input Sensitivity There are two settings for the sensitivity of the transceiver:

The Low Distortion (LD) setting is recommended for strong interference signals at the antenna input. It reduces sensitivity, and thus improves immunity.

The Low Noise (LN) setting increases the sensitivity, and thus improves the reception of weak signals.

Set/Get Values for Preset Page

200 preset pages can be stored in the radio and called up. Each contains the frequency and spacing parameters. These parameters can be set for each preset page.

Installation Info Information (up to 20 characters) can be entered to describe the radio more precisely.

Location Info Only the first 20 characters entered by using the R&S ZS 4200 appear on the radio display.

IP Address An IP address must be assigned for each radio module, which allows each module to be uniquely identified and operated in remote operating mode. Additionally, specifying the netmask and the gateway makes it possible to work within different subnets via a router.


Here you can enter the IP addresses of the remote control systems or clients that are allowed to access the radio. This protects the radio against unwanted/unknown accesses. If the list is blank (default), then any client with any IP address can access the radio.

BSS Enable The parameter is used to enable or disable the Best Signal Selection functionality. For more information please refer to chapter 3.11 Best Signal Selection.


3.17 6166.5368.02.01

Main/Standby Type The main/standby type declares if a radio should start up as an active main radio or as an inactive standby radio. If the common AC- or DC-supply of a main/standby installation is powered up, then the radio will boot accordingly.

Note: The parameter Main/Standby Type is also used for the Best Signal Selection if this functionality is enabled.

Line Interface in Local Mode

In local mode, the rear and front panel audio interfaces as well as the VoIP and E1 data streams operate in parallel (default). The rear panel audio line interface (including PTT) as well as the VoIP and E1 data streams can be disabled for the local mode. This allows independent use of the radio for a service technician where unwanted radio keying from the system-oriented PTT line input must be prevented.

Local Mode You can disable the LOC button on the radio to prevent the radio from being switched from remote mode to local mode.

Local Mode Timeout Local Mode will be quit automatically if there is no further activity on the front-panel radio keys or if local PTT (Push-To-Talk) is not re-keyed any longer. Timeout can be set between 60 s and 900 s, or disabled.

EXT VSWR Limit The external VSWR limit specifies the voltage threshold for the analog input EXT-VSWR (X7.8). Especially for installations with external circulators the voltage from an external SWR-detector can be connected to the radio in order to generate CBIT warning 0338. The external VSWR input is only processed during active TX state.

EXT VSWR Polarity Polarity of the external VSWR voltage. Positive polarity means the CBIT is generated if the measured value is above the defined limit. Negative polarity means the measured value is below the defined limit.

Single Channel Fixed frequency cannot be changed. Frequency must be configured before activating this function.

Motor Tuned Telsa Filter

It is possible to connect an external automatic filter to the radio. Either Telsa or R&S filter can be used. In order to activate RS-422 interface, the configuration parameter has to be enabled.

Note: The X-cross adapter KG42-Z75 is required for operation with the R&S filter Fx22x.

Note: Enabling the external automatic filter will limit the frequency range of the radio to 118 MHz … 155.9916 MHz.

Mute Loudspeaker The loudspeaker of the radio can be muted if the PTT is keyed.

External Power Amplifier

The parameter External Power Amplifier has to be set to R&S or Jotron in order to control an externally connected power amplifier. Please refer to chapter 3.13 External Power Amplifier.

Frequency Blocking Ranges

Up to eight frequency blocking ranges can be defined. The device will refuse any frequency set command from MMI local operation or from remote control which is within these frequency blocking ranges.

The configured frequency blocking ranges have to fit the radio’s frequency range from 112 MHz to155.991666 MHz.


6166.5368.02.01 3.18

PTT Signaling PTT can be keyed by a tone with a specified frequency that is present within AF signal. If the parameter is on, the tone is detected and controls the PTT function. The tone itself is suppressed within transmitted signal by a notch filter.

PTT Signaling Frequency

The frequency of the PTT tone is variable within a specified range.

PTT Signaling Threshold

The level threshold of the PTT tone detector is variable within specified range and is related to nominal audio signal level set by “TX Audio Level”.

Note: In case of low absolute levels, the S/N ratio in the system must be taken into account. Make sure that the S/N ratio does not fall below a specific value. The applicable value in each case is calculated from the audio level minus the PTT signaling level for the transmitter. If the setting with 0 dB in-band signaling is selected, the headroom for the sum level is reduced by 6 dB.

SQ/RSSI Signaling SQ can be indicated by a tone with a specified frequency that is present within AF signal. If the parameter is on, the tone is generated when SQ is open. A part of AF signal near the SQ tone frequency is suppressed by a notch filter.

An alternative setting is RSSI signaling. One of four tones within AF range 3 kHz to 3.4 kHz is generated depending on received signal strength. An appropriate low pass filter is used in order to suppress received AF signal in the affected AF range.

SQ Signaling Frequency

The frequency of the SQ tone is variable within a specified range.

SQ/RSSI Signaling Level

The level of the SQ tone generator is variable within specified range and is related to nominal audio signal level set by “RX Audio Level”.

Note: In case of low absolute levels, the S/N ratio in the system must be taken into account. Make sure that the S/N ratio does not fall below a specific value. The applicable value in each case is calculated from the audio level minus the signaling level for the receiver. If the setting with 0 dB in-band signaling is selected, the headroom for the sum level is reduced by 6 dB.

RSSI Output RSSI analog output can provide various linear curves depending on received signal strength. Curve “R&S Standard” is predefined, curve “User defined“ has variable parameters.

RSSI Output Curve Slope

RSSI analog output: Curve ”User defined” has the slope configurable.

RSSI Output Curve Offset

RSSI analog output: Curve ”User defined” has the offset configurable.

RSSI Output Curve Min. Voltage

RSSI analog output: Curve ”User defined” has the minimum output voltage limit configurable.

RSSI Output Curve Max. Voltage

RSSI analog output: Curve ”User defined” has the maximum output voltage limit configurable.


3.19 6166.5368.02.01

TX Preemphasis For the use especially with long telephone lines, the AF response shape can be adjusted in a way that higher frequencies have higher gain than lower frequencies. The value in dB specifies the gain at AF = 3400 Hz in comparison to AF = 800 Hz. Nominal TX audio level is always related to AF = 1 kHz. Default value is 0 dB which means that TX preemphasis is off.

SNMP Community String

Name of the SNMP communication community. It is used to restrict the network access.

SNMP Enable The parameter is used to enable and disable the SNMP functionality of the radio on the LAN interface.

If the parameter is set to "Disable", the SNMP functionality is disabled and only GB2PP protocol is supported via LAN. If the parameter is set to "Enable", both GB2PP and SNMP protocols are supported.

Note: It is strongly recommended to disable the SNMP protocol if only the GB2PP protocol is used.

E1 Alarm for Inactive Warning

The parameter is used to enable/disable the transfer of the inactive warning via the E1 interface.

DC-Battery Supervision

The voltage during battery operation can be monitored. If the voltage is too low, two responses in the radio can be triggered.

The Warning setting generates the CBIT warnings 0301 and 0401, which are output via the remote system connected.

The NOGO setting sets the TEST_OC signal at the output (connector X5.4) and initiates a switchover to the standby mode in a main/standby configuration. This setting is recommended if, for example, two separate DC networks are used for the main and standby radios.

AC-Main Supervision

The voltage during network operation can be monitored. If the voltage is too low, two responses in the radio can be triggered:

The warning setting generates the CBIT warnings 0302 and 0402, which are output via the remote system connected.

The NOGO setting sets the TEST_OC signal at the output (connector X5.4) and initiates a switchover to the standby mode in a main/standby configuration. This setting is recommended if, for example, two separate AC networks are used for the main and standby radios.

Note: If the AC-Mains fail, operation automatically switches to the standby radio. Otherwise the DC battery of the main radio would be unnecessarily discharged.

VoIP radio URI RX This is the unified identifier for VoIP communication of the RX module. This identifier consists of two parts concluded with the “@” sign user@<IP Address> or user@<Full Qualified Domain Name> eg. [email protected].

The URI can be up to 64 characters. Characters and other naming conventions have to follow the RFC 3986 rules. Using the reserved characters makes the URI invalid and thus the VoIP operation is not possible.

The default value of URI RX module is [email protected].

mailto:[email protected]


6166.5368.02.01 3.20

VoIP radio URI TX This is the unified identifier for VoIP communication of the TX module. This identifier consists of two parts concluded with the “@” sign user@<IP Address> or user@<Full Qualified Domain Name> eg. [email protected].

The URI can be up to 64 characters. Characters and other naming conventions have to follow the RFC 3986 rules. Using the reserved characters makes the URI invalid and thus the VoIP operation is not possible.

The default value of URI TX module is [email protected].

VoIP PTT Summation Mode

This setting is used for enabling/disabling of PTT summation for multiple RTP audio streams.

VoIP Jitter Buffer Prefetch Value

In order to compensate network delays, the VoIP implementation of the radio uses a so called Jitter Buffer. The adjustment of this buffer controls the delay between sender and receiver.

Note: An inadequate value can cause interrupted audio flow. The optimal value is system-specific and has to be found during the system-setup.

Note: This value influences the maximum confirmation delay. If the value is greater than 20 ms, the maximum confirmation delay is not compliant to ED-137-1.

Emergency VoIP URI ACL

The VoIP mode of the radio offers the possibility to configure the access for VoIP connections. Each entry contained in the URI ACL grants access to establish VoIP connections to the radio. In default configuration the URI ACL is a whitelist. This means that accessing the radio via VoIP is not restricted. The URI ACL can contain up to 20 entries with a maximum of 64 characters per entry.

Emergency VoIP URI ACL stores URI of the VoIP clients which are allowed to access the radio with either normal or emergency call priority.

Normal VoIP URI ACL Compared to Emergency VoIP URI ACL the Normal VoIP URI ACL stores URI of the VoIP clients which are allowed to access the radio with normal call priority.

Permit Only ACL URI Call

This configuration parameter enables or disables acceptance of the VoIP session requests which only have URIs matching the VoIP URI ACL lists.

Coupling PTT Summation

This parameter enables or disables additional summing of the VoIP RTP stream of the SIP call-type “coupling” and PTT-type “coupling” together with the RTP streams selected for the transmission.

Note: The setting of this parameter will end all active SIP sessions.

Primary Domain Name Server

This parameter is used to setup an IP address of a Domain Name Server.

Secondary Domain Name Server

This parameter is used to setup an IP address of a Domain Name Server which is used for backup purposes.

RTP Port Range Start The real time transport protocol uses several IP ports for communication with VCS or the R&S GB4000V. This parameter sets the start port for the port range which can be used for VoIP audio streams.

Carrier Offset TX carrier offset. Configuration parameter “5-carrier offset” must be enabled in order to provide −8 kHz / −4 kHz / +4 kHz / +8 kHz offsets.

For further details on the TX offset activation see chapter 3.4.7.2.1 Explanation of Offset Activation.

Preset Page Number Number of the selected preset page. Zero is displayed in case of an individual frequency setting, channel spacing, modulation mode, and offset.

TX Audio Level E1 This parameter refers to the E1 modulation input (connector X13, X14). With the default setting, the modulation sensitivity is 0 dBm0 which means that at the E1 audio level of 0 dBm0 the AM transmitter is driven and modulated at 90 % modulation. The input can be configured from −30 dBm0 to 0 dBm0 in accordance with the E1 infrastructure and the incoming signal levels. The sensitivity is greatest at −30 dBm0 which means that the full modulation of 90 % modulation is achieved even at a low level.

Note: The achieved modulation depth depends on the “TX AM Modulation Depth” parameter. The relationship described above is valid for TX AM Modulation Depth configured to 90 % (by default).

RX Audio Level E1 This parameter refers to the E1 audio output of the AM receiver (connector X13). With the default setting of −4 dBm0, an effective level of –4dBm0 is applied at 60 % AM modulation of the current receive signal (–0.5 dBm0 at 90 % modulation). The output can be configured from −30 dBm0 to –4 dBm0 in accordance with the E1 infrastructure.


6166.5368.02.01 3.22

TX Audio Level VoIP This parameter refers to the VoIP modulation input. With the default setting, the modulation sensitivity is 0 dBm0 which means that at the VoIP audio level of 0 dBm0 the AM transmitter is driven and modulated at 90 % modulation. The input can be configured from −30 dBm0 to 0 dBm0 in accordance with the VoIP infrastructure and the incoming signal levels. The sensitivity is greatest at −30 dBm0 which means that the full modulation of 90 % modulation is achieved even at a low level.

Note: The achieved modulation depth depends on the “TX AM Modulation Depth” parameter. The relationship described above is valid for TX AM Modulation Depth configured to 90% (by default).

Note: The default setting ensures the compliance with the ED-137 requirement of 30 % AM modulation depth at −10 dBm0 audio level. If the VoIP infrastructure complies with the ED-137, the default value shall be left unchanged.

RX Audio Level VoIP This parameter refers to the VoIP audio output of the AM receiver. With the default setting of −4 dBm0, an effective level of –4dBm0 is applied at 60 % AM modulation of the current receive signal (–0.5 dBm0 at 90 % modulation). The output can be configured from −30 dBm0 to –4 dBm0 in accordance with the VoIP infrastructure.

Note: The default setting ensures the compliance with the ED-137 requirement of −10 dBm0 at 30% AM modulation depth. If the VoIP infrastructure complies with the ED-137, the default value shall be left unchanged.

TX Audio ALC E1 The automatic level control for the E1 audio modulation can be switched on and off. When this function is activated, the set AM modulation depth (see TX AM Modulation Depth parameter) is ensured over a dynamic range of ±15 dB at the TX E1 audio interface (X13, X14).

Note: If the automatic level control is active in the system external to the radio, then the level control of the radio should be switched off.

RX Audio AGC E1 The automatic gain control in the AM demodulator can be switched on and off. In the range from 30 % to 90 % modulation depth, the signal (E1 RX Audio) remains constant.

TX Audio ALC VoIP The automatic level control for the VoIP audio modulation can be switched on and off. When this function is activated, the set AM modulation depth (see TX AM Modulation Depth parameter) is ensured over a dynamic range of ±15 dB at the TX VoIP audio interface.

Note: If an automatic level control is active in the system external to the radio, then the level control of the radio should be switched off.

RX Audio AGC VoIP The automatic gain control in the AM demodulator can be switched on and off. In the range from 30 % to 90 % modulation depth, the signal (VoIP RX Audio) remains constant.

IPv6 Enabled This parameter is used to enable IPv6 IP-version. The radio can use either IPv4 or IPv6 for LAN communication. Simultaneous operation of IPv4 and IPv6 is not possible. If this parameter is set to “Enabled”, IPv6 will be used and IPv4 will be automatically disabled.

Note: DHCP will be automatically disabled if IPv6 is enabled by the user.

Note: Both IP configuration and Access Control List of the RX and TX modules must be configured according to the selected IP-version.


3.23 6166.5368.02.01

DHCP Enabled

This parameter is used to enable dynamic host configuration (DHCP). If enabled, the radio uses DHCP and can learn an IP address from a DHCP server installed in the network.

Note: DHCP is supported in IPv4 network only. It is not possible to enable DHCP while IPv6 is being used.

TX Hostname TX Hostname is assigned to the TX module. Characters and other naming conventions must comply with the RFC 952 rules. The parameter is included in the initial DHCP message sent from the radio to the DHCP server. If the DHCP server is configured accordingly, this information can be used to inform a DNS server about a potential change in the mapping of the IP address to hostname.

RX Hostname RX Hostname is assigned to the RX module. Characters and other naming conventions must comply with the RFC 952 rules. The parameter is included in the initial DHCP message sent from the radio to the DHCP server. If the DHCP server is configured accordingly, this information can be used to inform a DNS server about a potential change in the mapping of the IP address to hostname.

Local Mode Warning The radio can be configured in such a way that pressing the LOC button on the radio generates the CBIT warnings 0336 and 0415, which are output via the remote system connected.

USB Connect Warning The radio can be configured in such a way that a USB access via a service PC generates the CBIT warnings 0335 and 0414, which are output via the remote system connected.

External VSWR Warning

The radio could be configured in such a way that a warning will be generated if the limit external VSWR EXT_VSWR (X7.8) is exceeded.

The external VSWR CBIT warning 0338 will be sent to the remote control system connected if the external VSWR limit is exceeded.

The warning can be configured as NOGO warning in order to request a main/standby switchover via TEST_OC X5.4.

TX Power Low Warning

If the power is 3 dB lower than expected, the radio will generate the NOGO warning 0323 and will request a main/standby switchover via TEST_OC X5.4.

VSWR Warning The VSWR on the transmitter output (X3) is monitored during operation. If the VSWR is higher than 2, a NOGO warning will be generated.

The NOGO warning VSWR 0331 will be sent to the remote control system connected if the VSWR on the transmitter is above 2.


PSU Fan Warning The rotation of the power supply fan is internally monitored and will cause a warning if the fan is not running as expected.

The NOGO warning PSU fan 0201 will be sent to the remote control system connected if the power supply fan is not working well.



6166.5368.02.01 3.24

The NOGO warning main fan 0103 will be sent to the remote control system connected if the main fan of the radio is not working well.


Inactive Warning The radio can be configured in such a way that if the radio is inactive, it generates the CBIT Warning 0101 which is output via the remote system connected.

User Contact Warning The radio can be configured in such a way that a warning will be generated if the user contact X7.15 or X11.15 is high. The USER CONTACT WARNING 0342 or 0430 will be sent to the remote control system.

E1 RAI Warning The transmission on the E1 interface is monitored. If errors are occurring on the transmission system, they are indicated with an alarm indication (RAI).

The NOGO warning E1 RAI (CBIT TX 0347 or RX 0437) will be sent to the connected remote control system if the remote alarm (RAI) is indicated.

The warning can be configured as NOGO warning in order to request a main/standby switchover via the TEST_OC X5.4 (TX) or X10.4 (RX).

E1 CRC4 ERROR Warning

The bit error rate in the E1 interface is monitored. If bit errors are occurring, they are indicated with an excessive bit error rate (CRC4) CBIT.

The NOGO warning E1 CRC4 ERROR (CBIT TX 0348 or RX 0438) will be sent to the connected remote control system if the excessive bit error rate (CRC4) is indicated.

The warning can be configured as NOGO warning in order to request a main/standby switchover via the TEST_OC X5.4 (TX) or X10.4 (RX).

E1 LOS Loss of the incoming signal of 2048 kbit/s on E1 interface.

The NoGo warning E1 LOS (CBIT TX 0345 or RX 0435) will be triggered if the incoming signal on E1 interface is lost.

The NoGo warning can be disabled. This is useful to avoid a main/standby switchover request via the TEST_OC X5.4 (TX) or X10.4 (RX).

E1 LOF Loss of frame alignment and channel associated signaling (CAS) (without recovery in timeout).

The NoGo warning E1 LOF (CBIT TX 0346 or RX 0436) will be triggered if the frame alignment and CAS on E1 interface is lost.

Note: If the radio is set to local mode (LOC), remote control commands will be refused. Local mode has the highest priority and interrupts any remote control fixed sessions. Parameters can only be monitored remotely when the radio is in local mode.

When the radio is in the local mode, you can connect a headset and power up the transmitter by pressing the PTT key at any time.

In the receive mode, the front-panel receive audio signal is always audible. In other words, the internal loudspeaker and the headset audio connector are always active and the volume of the two can be controlled by the assigned potentiometer.

Note: The local mode causes the termination of all active VoIP connections if the parameter “Line Interface in Local” mode is disabled. As long as the radio is in local mode, all VoIP connection requests are rejected.

All parameters and measurements can be displayed in the remote and local modes.

3.4.2.6 SQ Key

Function By using the SQ key, you can open or close noise suppression (squelch) at any time independently of the current menu. The only precondition is the local mode.

Squelch behavior The switch-on and switch-off behavior of noise suppression (squelch) and the opening and closing of the squelch relay at the output of the radio depend on the RSSI squelch threshold and the S/N squelch threshold. The thresholds can be configured using the Service and Maintenance Tool R&S ZS 4200 (see chapter 3.3 Configuring with the R&S ZS 4200).

The following table shows the states on the radio as a function of the thresholds.

3.4.2.7 LOC Key

LOC Key\LOC Key "Radio".doc

Function on radio The LOC key enables you to switch between local and remote mode at any time independently of the current menu. The local mode has priority over remote accesses, i.e. a remote fixed session over the Ethernet − LAN interface will automatically be terminated if you select local mode by pressing this key. If you press the key a second time, local mode will be terminated, at which point a remote client must re-initiate the session to the device (or to the modules).

By pressing the LOC key the radio will enter the local mode.

Note: The local mode causes the termination of all active VoIP connections if the parameter “Line Interface in Local” mode is disabled. As long as the radio is in local mode, all VoIP connection requests are rejected.

Deactivation You can deactivate the LOC key from the service PC (USB configuration), thus blocking local mode altogether (protection from improper use).

Key operation messages

By using the service PC (USB), you can configure whether a local access leads to a warning message or not. The local mode state would then be reflected in the CBIT status. In addition, the start and end of the local mode will be stored in the event log together with time information. If applicable, this information will also be sent to the fault management system.

3.4.7.2.1 Explanation of Offset Activation

The radio offers a number of different offsets that can be activated. As the handling of unsupported offsets is different from the handling of any other unsupported parameter, an explanation is given here to avoid misunderstandings. Normally unsupported parameters or commands are rejected by the radio with an error message.

Whether an offset is supported depends on a combination of other parameters, such as spacing or mode. Please refer to the ICD for a detailed table with all permitted combinations of modes, offsets and spacings that can be set to the hardware.

Note: The radio behavior is specified as follows: offsets that are not permitted in certain spacing will be accepted and stored by the radio, but not activated in the hardware. Only when a spacing which supports this stored offset is activated, the offset will be activated in the hardware. The consequence of storing the offset is that it can be read out over all interfaces and it is displayed on the MMI, even if it is not activated in the hardware because this combination of offset and spacing is not permitted.

This chapter This chapter provides information about the cabling and configuration of the radio pair for the main/standby operation.

3.6.1 Introduction/Overview

Introduction Two radios can be connected together in a main/standby configuration. The main radio is used for radiocommunication. The standby radio takes over if a failure or critical error occurs on the main radio.

All CBIT events with the level E (Error) switch the main radio to the standby mode and the standby radio to the main mode. CBIT events can be configured as an error (E) or a warning (W) (see chapter 3.3 Configuring with the R&S ZS 4200).

3.6.1.1 Behavior of the Main/Standby Configuration with Power On

Description Both radios have to be powered up. If there is no failure, the radios are booting and will get into the following state: The radio configured as "Main" has to indicate the "GO" and "VOP" LEDs and to show the status "ACT" on the display. The radio CBIT status is "OK" (see Fig. 3.69 Active device). The second radio configured as "Standby" has to indicate the "GO" LED while the "VOP" LED remains dark. In addition, the display shows the status "INACT". The figures below show the radios displays after booting (see Fig. 3.70 Inactive device).

The inactive standby radio becomes active after switching to local mode, as long as the radio is in the activation state “AUTO”. The main active radio becomes inactive. After leaving the local mode both radios will keep their state.

3.6.1.2 Behavior at Remote Control

Description When the command "MS_GO" has been sent via remote control, the radio switches to ACTIVE state irrespective of the previous state. Referring to the settings mentioned above, the radio which got this command becomes active and the partner device (cross-connected via X5) becomes inactive. The "MS_GO" command is ignored by the radio if at least one of its modules is set to OFF state. A radio can be set to OFF or to AUTO state using the "MS_AC" command. When the command "MS_AC" with the “OFF” parameter was sent via remote control, the radio switches to INACTIVE state irrespective of the previous state. The partner device (X5 or X10) gets ACTIVE if it is in AUTO state.

There are different ways to switch between the radio states. Using the remote control mode, it is possible to send the "MS_GO" or "MS_AC" command to toggle the radio state. In the local mode, it is possible to change the activation state of the radio. After leaving the local mode, the radio will keep this state.

3.6.1.3 Behavior in Case of Device Errors

Description If an error or NOGO warning occurs on the "Main" radio, the "Standby" radio will be activated via the TEST_OC line. The "Standby" device will become active and switches the "Main" radio inactive using the cross-connected *OFF line.

If an error disappears on the inactive "Main" radio, the "Standby" radio will stay active. In case there will be an error on the active "Standby" device, a switchover to the "Main" radio will be done if no error is active on this radio.

Fig. 3.76 Main/Standby cabling PTT Type II. (cutout).

Note: If transceivers are configured for main/standby operation, the "TEST_OC" and "*OFF” contacts of only one module (receiver or transmitter) must be connected together. The "TEST_OC" and "*OFF" contacts of the two modules are internally hard-wired in the transceiver.

3.6.3 Configuration

Setting using the R&S ZS 4200

1. Use the Service and Maintenance Tool R&S ZS 4200 to configure one of the two devices as “Main (0)” and the other one as “Standby (1)” unit.

Setting on the radio or via remote control

2. The following settings have to be done in the local mode or via the remote control system.

Both radios (in transceiver radios: four radio modules – 2x TX and 2x RX) have to be set to "AUTO" via the remote control command "MS_AC" or they could be configured to activation state "ON" in the local mode (see Fig. 3.71).

After leaving the local mode, the device will automatically switch to the "AUTO" mode and will be ready for the main/standby switchover (see Fig. 3.72).

Note: The operation of the Service and Maintenance Tool R&S ZS 4200 is described in detail in the corresponding operating manual.


6166.5368.02.01 3.78

3.6.4 Limitations/Notes

Please note that there are certain limitations for the main/standby operation:

Main and Standby radio configuration with NoGo state on radios wired as 1:1 M/S pair must be avoided In case of the NoGo state on both radios, both TEST_OC lines become open (both radios are reporting a request for M/S switchover). This state brings the radios to ACTIVE state when they can receive and transmit simultaneously. This can be dangerous especially for transmitters. Example of an incorrect radio configuration: – HW Configuration: Main and Standby radios are supplied from the same mains. Both radios are connected to a DC backup battery – CBIT Configuration: AC-Main Supervision is configured as "NoGo" on both Main and Stadby radios. If the AC main fails, the radios will request the M/S switchover and switch to the unwanted ACTIVE state

Note: If one radio is in local mode while the other one is in remote mode, then the locally operated radio is active and the second one is inactive. This setting remains even when the local mode is left. The main/standby switchover capability of the radio pair is now available.

Note: The “Inactive Warning” parameter should be set to “Disable” to avoid the inactive "Standby" radio showing the CBIT event “INACTIVE WARNING”.

Note: Set the “Line Interface in Local Mode” parameter to “Disable”.

Note: Make sure that all operational parameters are equal on both radios (with exception of IP address).

3.8 In-Band Signaling

0. In-band Signaling\In-band Signaling "Radio".doc

This chapter This chapter provides information about the functioning, configuration and conditions of the radio for the in-band signaling.


Introduction To reduce the number of lines, in particular for transmitting signals over long distances, the use of the bidirectional in-band technique via a 2-pair AF/telephone line per radio unit (receiver, transmitter or transceiver) is recommended.

The R&S Series 4200 radios support the following in-band functions:

Signaling of PTT on transmitter side Signaling of SQ on receiver side Audio in-band tones for RSSI signaling on receiver side

Signaling of PTT PTT can be keyed by a tone with a specified frequency that is present within AF signal. If the parameter is ON, the in-band tone is detected and controls the PTT function. The tone itself is suppressed within transmitted signal by a notch filter. The PTT can be signaled via the TX audio channel with the tones of 2040 Hz, 2300 Hz, 2970 Hz or 3100 Hz.

Signaling of SQ SQ can be indicated by a tone with a specified frequency that is present within AF signal. If the In-Band signaling is configured to SQ, the in-band tone is generated when SQ is open (SQ threshold is met). If the parameter is configured to INVSQ, the in-band tone is generated when the SQ threshold is not met. A part of AF signal near the SQ tone frequency is suppressed by a notch filter. The squelch can be signalled via the RX audio channel with the tones of 1225 Hz, 2040 Hz, 2175 Hz, 2440 Hz, 2970 Hz or 3300 Hz.

The level of the SQ tone is variable within specified range and is related to nominal audio signal level set by “RX Audio Level”.

Audio in-band tones for RSSI signaling

At the RSSI selection one of four tone frequencies is generated depending on received signal strength and is transmitted via the in-band audio channel (X10.2/X10.3) (see Fig. 3.79 Tone used for RSSI signal quality). The appropriate low pass filter is used in order to suppress received AF signal in the affected AF range. During one transmission cycle the RSSI signaling frequency is kept constant. The level of the RSSI tone is variable within a specified range and is related to nominal audio signal level.

Note: Once the SQ criteria is met, the signal strength is evaluated. An appropriate in-band tone is selected and kept unchanged for the whole period (until the SQ release).

3390 Hz (good quality) SQ criteria met, RSSI > 30 µV

3300 Hz (middle quality) SQ criteria met, 6µV < RSSI < 30 µV

3210 Hz (bad quality) SQ criteria met, RSSI < 6 µV

3180 Hz (no signal) SQ criteria not met

This chapter This chapter provides information about the characteristic and configuration of the analog RSSI output on the radio.


Introduction The received signal strength indication (RSSI) is available as an analog voltage via the RSSI output on the rear side of the radio (X11.8).

The R&S Series 4200 radios support a configurable analog RSSI output.

RSSI Output Type The RSSI output characteristic can be configured with the “RSSI Output” parameter in two different modes:

“R&S Standard” type with a linear dependency of the received signal strength predefined by the manufacturer (see Fig. 3.80 RSSI output type − R&S Standard)

“User defined” type with variable user defined parameter settings to adapt the radio behavior to customer’s needs (see Fig. 3.81 RSSI output type − User defined)

R&S Standard The RSSI output type “R&S Standard” has a linear characteristic with the slope of 38.5 mV/dB and offset of 4620 mV @ 0 dBm.

Fig. 3.80 RSSI output type − R&S Standard.

RSSI Output Characteristic R&S XU 4200

Introduction The radio can be configured for ACARS data operation (2400 Bps).

In this case a faster RF front-end control is in action. The attack and decay time is in accordance with the ETSI EN 300676 standard. An external ACARS modem needs to be used for ACARS operation. Communication between the modem and the radio is via 2 tones: 1200 Hz (bit change from previous) and 2400 Hz (no bit change from previous).

3.11 Best Signal Selection

0. Best Signal Selection\Best Signal Selection "Radio".doc

This chapter This chapter provides information about the cabling, configuration and conditions when using a pair of radios for best signal selection (BSS).


Function description To optimize signal quality in difficult reception environments (shadowing, etc.), two radios can be operated at different sites at the same frequency, each with a separate antenna.

The radios automatically detect the one which receives the stronger audio signal from the distant station, and this signal is connected through.

The "best signal" is determined by means of the two RSSI signals during the first 200 ms of each radio message (PTT). The radio offering better reception is then used during the entire radio message.

The radio which first switches the squelch on delivers a signal to the audio line. After 200 ms the RSSI is sampled once and the radio with larger RSSI value switches its signal to the audio line for the rest of the transmitted audio burst. A new evaluation is done when the squelch opens again. The following timing diagrams show the 2 possible cases (radio 1 with stronger RSSI, radio 2 with stronger RSSI)

Fig. 3.85 Radio 1 has a stronger receive signal, no switchover audio signal.

Fig. 3.86 Radio 2 has a stronger receive signal, audio signal is switched after 200 ms from radio 1 to radio 2.

3.11.2 Cabling

Instructions 1. Connect the USER_OUT2 (X11.14) signal to the /AF_INHIBIT (X11.7) input and the RSSI (X11.8) signal to the EXT_RSSI (X11.5) input on each radio.

2. Connect the SQ+ (X10.8), SQ- (X10.8), AUDIO_RxA (X10.2) and AUDIO_RxB (X10.3) outputs of the two radios in parallel.

Cabling

Fig. 3.87 Cabling for best signal selection.

Note: The maximum permissible length of the cables between the two radios depends on the cable type. Make sure that the DC loop resistance remains < 100 Ohm for each cable.

Note: Using the E1 interface together with the BSS function is not possible.

Note: With the AUDIO_RxA and AUDIO_RxB signals connected in parallel the output impedance will be halved to a value of 300 Ohm.


Configuration of radios using the R&S ZS 4200

Use the Service and Maintenance Tool R&S ZS 4200 to configure the radios for control of the best signal selection function.

1. Configure one of the two radios as the "Main (0)" and the other one as the "Standby (1)" radio.

2. Set the “BSS Enable” parameter to "Enable" on both radios.

3. Set the “RSSI Output” parameter to "R&S Standard" on both radios.

Setting on radios 4. Set the same frequency on both radios.

Conditions For the following parameters identical settings must be made on both radios:

SN Squelch Threshold RSSI Squelch Threshold S/N RSSI Logical Operation RX Input Sensitivity


Best Signal Selection R&S XU 4200

3.93 6166.5368.02.01


Limitations Please note that there are certain limitations to radio operation if the best signal selection function is active:

The radios cannot be operated in the main/standby mode as described in chapter 3.6 Main/Standby Operation (1:1). Both radios must be operated in active mode

The USER_OUT2 output cannot be used for remote control of a user via the management system (UO (user out) GB2PP code)

Note: If the signal strength is nearly identical on both radios, it may happen that the radio with the weaker signal is connected to the distant station because of measurement tolerances.

0. Audio Data via E1 Interface\Audio Data via E1 Interface "Radio".doc

This chapter This chapter provides information about the cabling, configuration and conditions for using the E1 interface.


Introduction The radio is equipped with an E1 interface for the digital transmission of audio signals.

Description of the E1 interface

The E1 interface is implemented according to ITU standards G.703, G.704, G.711 and G.732. The frame structure is CAS multiframe. The PCM coded audio signal (A-law) is transmitted in the timeslot TS1 and the signaling is transmitted in timeslot TS16. The channel associated signaling (CAS) used in TS16 is specified below.

Signaling code The signaling is coded in bits A, B, C, D as follows (first bit = A):

CAS coding for direction to transceiver (TX)

PTT active: PTT inactive:

1010 all other states

CAS coding for direction from transceiver (RX)

Squelch closed/Device status OK: Level < 6 μV: Level > 6 μV to 30 μV: Level > 30 μV: Device status NOGO: Reserved:

0101 0011 0110 1100 1111 all other states

Note: Once the SQ criteria are met, the signal strength is evaluated. An appropriate CAS code is selected and kept unchanged for the whole period (until the SQ release).

Error handling If NOGO errors occur in the radio, an alarm indication signal (AIS) is sent via the E1 interface. If a CAS-coded PTT signal is received during this time, it is ignored.

The squelch signaling is overwritten by the "Device status NOGO" signaling.

The „Alarm for Inactive Warning“ parameter can be used to enable or disable the sending of AIS also when the radio goes to inactive mode (stand-by). This allows implementing an automatic switchover to another radio if the multiplexer used on site supports such function.

The PTT function will be disabled if one of the following states of the E1 interface are detected:

LOS (Loss of Signal) LFA (Loss of Frame Alignment) Loss of multiframe Loss of synchronization External D-bit set (remote alarm indication (RAI)) Other conditions that can lead to misinterpretation of CAS information

For remote control it is required to have additional LAN connection to the remote control system (see chapter 3.5 Remote Cotrol via LAN).

3.13.1 External Power Amplifier R&S VU220L

This chapter This chapter provides information on how to operate the radio together with the R&S VU220L VHF external power amplifier.


Introduction The radio supports the use of an external power amplifier.

The R&S VU220L VHF external power amplifier is set to a fixed gain of 10 dB. This means that with input power of 10 W signals will be transmitted at output power of 100 W.

The amplifier is operated (switched on/off) via the PTT signal which controls the TX/RX relay of the amplifier. In standby operation the signal from the antenna is passed through the amplifier to the amplifier's RF input. Thus, the signal from the antenna is available at the receiver. When the PTT is active, the signal from the transmitter is passed through the TX/RX relay of the amplifier to the amplifier's RF input. The amplified signal is passed to the antenna.

In case of any error an alarm signal is generated by the amplifier at the Test pin (X200.4). The alarm signal can be connected to the radio's USER_IN input, X7.15. The CBIT event 0342 "User Contact Warning" can be configured to indicate the alarm.

3.13.1.2 Cabling

Instructions 1. Connect the USER_OUT output (X7.14) of the radio to the *PTT input (X200.3) of the amplifier and connect the ground contacts of the two units (X7.3, X7.4, X7.9 and X200.1, 15) with one another.

2. Connect the Common Antenna output (X3) of the radio to the RF IN input (X5) of the amplifier.

3. If necessary, connect the Test control signal (X200.4) of the amplifier to the USER_IN input (X7.15) of the radio.

4. Connect the RF OUT output of the amplifier to the antenna.

Configuration of radio using the R&S ZS 4200

Use the Service and Maintenance Tool R&S ZS 4200 to configure the radio for controlling the external power amplifier.

1. Set the “External Power Amplifier” parameter on the radio to "R&S".

2. Set the “TX Output Power Level” parameter to max. 20 W for both the "Normal" and the "Low" setting.

3. Set the “User Contact Warning” to “Warning” level.


ATTENTION

Risk of destruction of amplifier due to high input power

The R&S VU220L VHF external power amplifier can be operated only at a maximum input power of 20 W. Higher input power can result in destruction of the amplifier!

3.13.2 External Power Amplifier Jotron PAV-100/200

This chapter This chapter provides information on how to operate the radio together with the Jotron VHF external power amplifier.


Introduction The radio supports the use of an external power amplifier.

The Jotron VHF external power amplifier is set to a fixed gain of 6 dB. This means that with input power of 25 W signals will be transmitted at output power of 100 W. With an input of maximum 50 W, the RF signal is transmitted with 200 W.

The amplifier is operated (switched on/off) via the PTT signal which controls the TX/RX relay of the amplifier. In standby operation the signal from the antenna is passed through the amplifier to the amplifier's RF input. Thus, the signal from the antenna is available at the receiver. When the PTT is active, the signal from the transmitter is passed through the TX/RX relay of the amplifier to the amplifier's RF input. The amplified signal is passed to the antenna.

In case of high antenna mismatch SWR ALARM signal is generated by the amplifier at the Remote Facility Connector, pin 9 and 10. The alarm signal shall be connected to the radio's USER_IN input, X7.15. When the USER_IN input is grounded, the radio switches RF Power to “Low”. CBITs 0349 “EXT PA ALARM” and 0350 “PWR REDUCED TO LOW” are generated.

3.105 6166.5368.02.01

3.15 Audio via VoIP (Optional) VoIP Mode\VoIP Mode "Radio".doc

This chapter This chapter provides information about the VoIP mode. The R&S S4200 radio offers the possibility of digital audio transmission via voice over internet protocol (VoIP). VoIP is a protocol driven communication standard. VoIP is implemented according to EUROCAE ED-137B, part 1.


Introduction This chapter explains basic mechanisms of VoIP communication. VoIP for Air Traffic Management (ATM) represents an IP communication standard which is adapted for ATM requirements.

Note: VoIP is used for communication between a voice communication system (VCS) or the R&S GB4000V over an IP network.

VoIP for ATM VoIP standard uses the following protocols:

SIP (Session Initiation Protocol)

Application layer protocol for establishing, modifying and terminating multimedia sessions based on RFC 3261.

SDP (Session Description Protocol)

Application layer protocol used for defining and negotiation of session parameters which are used for a two-way RTP communication based on RFC 4566.

RTP (Real-Time Transport Protocol)

Application layer protocol used for transporting audio data via network based on RFC 3550.

R2S Protocol (R2 Signaling Protocol)

Protocol which offers a mechanism for “Keep Alive” signalling to control the connection between the VCS or the R&S GB4000V and the radio.

3.15.5 VoIP Information on Standard Operation Screen

Introduction This chapter describes behavior on the standard operation screen while the radio is running in VoIP mode.

The standard operation screen informs the user about active SIP sessions of the radio. This information contains the number of active SIP sessions for the RX (0) and TX (1) module.

The information of active SIP sessions replaces the information “ACT/INACT” on the standard operation screen.

3.15.6 VoIP Connections

Introduction This chapter gives an overview about the network-based communication between VCS or the R&S GB4000V and the radio.

In transceivers each module (RX/TX) manages separated VoIP connections. Each connection consists of two parts:

Session related connections (SIP/SDP)

Audio stream related connections (RTP/R2S)

The figure below shows that a VoIP connection to the radio always consists of both a SIP/SDP and an RTP/R2S connection. VoIP connections need to be established for each module. Therefore, a transceiver in VoIP operation mode will always have at least one connection to the RX and one connection to the TX module. Note that each module can have a maximum of two concurrent SIP/RTP sessions.

Fig. 3.95 VoIP Connections.


3.109 6166.5368.02.01

3.15.7 VoIP Connection Establishment

Introduction This chapter explains the way from session initiation to audio transmission via VoIP. The explanation of the connection establishment is independent from the radio modules.

VoIP is a session-based communication standard. This means that audio data transmission requires a mechanism to synchronize the two endpoints (RX/TX and VCS/R&S GB4000V) also called user agents (UA). This synchronization of endpoint capabilities is done by SIP (see chapter 3.15.1) and SDP (see chapter 3.15.1). In this case SIP is used to initiate a session and SDP is used for negotiating the endpoint capabilities.

The connection establishment between two user agents contains two phases:

Session initiation (see chapter 3.15.6)

Audio communication (see chapter 3.15.6)

Session Initiation During session initiation the user agent one (VCS or R&S GB4000V) tries to connect to the user agent two (R&S S4200) by using the session initiation protocol (SIP). The identification between the two user agents is done by unified resource identifier (URI). The user agent two (R&S S4200) checks its Emergency and Normal VoIP ACLs whether the requesting user agent is allowed to connect. The VoIP ACL contains the URIs being allowed to connect.

Note: The VoIP ACL can be used as a whitelist. This allows all user agents to connect to the radio (no URI restriction). By using the session description protocol (SDP) both user agents negotiate their capabilities (e.g. used codec etc.). If the whole negotiating process succeeds, the session between both user agents is established. This establishment is the basis for the audio communication. This means that without an established SIP session no audio data can be transferred.

Note: The SIP session keeps existing until one of the user agents terminates the session or the network connection fails.

Audio Communication

After successful establishment of a SIP session the result of the negotiating process between both user agents will be used to configure the RTP-based audio transmission (e.g. codec to use, ports to use etc.).

Note: The real time transport protocol uses even ports higher than 5000. If one user agent terminates the SIP session, the corresponding RTP connection will also be terminated.

3.15.8 AM Voice Functionality with VoIP Interface

Introduction This chapter is an overview of AM Voice Functionality which influences the VoIP communication.

AF Inhibit The AF Inhibit functionality is working but it is not signalled via the VoIP. The AF Inhibit input X11.7 on the rear panel should be left unconnected to avoid malfunction of the VoIP operation.

TX Inhibit The TX Inhibit functionality is signalled back via the VoIP.

True Sidetone Muting of the receiver due to True Sidetone is not indicated via the VoIP.

3.15.9 Parallel Operation of the Analog and VoIP Audio Interfaces

Introduction Analog interface functionality remains unchanged when VoIP audio interface is selected (see chapter 3.3).

TX Audio Basic interface X5

Radio functionality related to TX Audio Basic interface X5 remains unchanged when VoIP audio interface is selected. Transmitter can be keyed via VoIP interface or using rear PTT input (connector X5.8/X5.9). In-band PTT can be configured on X5 interface as well (see chapter 3.8 In-band Signaling).

Note: Analog transmitting via X5 and via VoIP cannot work simultaneously. Only one PTT and audio source is accepted at a time.

Note: Analog Audio Basic Interface is always considered by the transmitter as PTT-TYPE “Normal”. Analog audio transmission can be interrupted when PTT-TYPE “Coupling”, “Priority”, or “Emergency” is coming over VoIP interface.The PTT coming from the TX Audio Basic interface X5 towards the VCS is indicated via the RTP Keep Alive with PTT-ID set to 63.

RX Audio Basic interface X10

Radio functionality related to RX Audio Basic interface X10 remains unchanged when VoIP audio interface is selected. Received demodulated audio signal is available on Analog and VoIP interfaces in parallel.

Note: When in-band signalling is enabled (SQ or RSSI, see chapter 3.8 In-band Signaling), the tones are present only on RX Audio Basic interface X10.

Introduction The software download can be done using the Service and Maintenance Tool R&S ZS4200. There is a possibility to perform the software download remotely via the LAN interface (see Fig. 3.97) or by using the local USB interface (see Fig. 3.98).

Note: For details (e.g. IP address), please refer to the Service and Maintenance Tool R&S ZS4200 software manual.

Fig. 3.97 Software download via LAN.

Fig. 3.98 Software download via USB.

Partition management

The radio is equipped with two different partitions; each of them can be updated with a certain software version. The software versions in a partition 1 may be different from the version in a partition 2.

The radio may be booted from each partition. The partition to be booted can be selected with the LAN command “RU_SI” or by using the Service and Maintenance Tool R&S ZS 4200. For more details, see the Service and Maintenance Tool R&S ZS 4200 software manual and the ICD.

Note: As the R&S XU 4200 contains 3 modules (receiver, transmitter and MMI modules), there is a partition 1 and a partition 2 in each module.

Software Download R&S XU 4200

3.113 6166.5368.02.01

USB Download If the radio is updated via USB interface, always the first partition is updated. The Service and Maintenance Tool R&S ZS 4200 switches the radio into an update mode, which interrupts the operation and disables all interfaces.

After the software download the radio always boots from the partition 1.

Remote Download via LAN

The software download on the LAN interface can be done in parallel to the operation of the radio. The update is always done into the partition which was not used for booting. This means that if the radio was booted from the partition 1, the remote download will be done into the partition 2 and vice versa.

After the download has been completed the user can choose when to switch the radio into the updated partition. This is done by selecting the partition which has been updated as the boot partition and then commanding the radio to reboot. Then, the radio always reboots from the same partition until the partition is changed manually via a remote control command.

Recovery mechanism

The radio is equipped with a recovery mechanism. In two defined situations, the radio will automatically switch from one partition and try to boot the other, currently an inactive partition:

1. The radio is rebooted after a software update and this reboot fail.

2. The user manually switches the partition and the succeeding reboot fails.

Note: The normal booting time of the radio is less than 1 minute. Last Page of Chapter 3\\Last Page of Chapte3 "Radio".doc

4.2.3 Unexpected Radio Restart

This chapter This chapter describes the process of troubleshooting and possible restart triggers in case of an unexpected restart of the radio.

Radio restart triggers

There are two main radio restart triggers:

External triggers (can be requested, e.g. user, remote client; or unrequested, e.g. power line interruption)

Internal triggers (always unrequested, e.g. WatchDog (WD), Partition Management)

In order to recognize the exact trigger of the radio restart, it is necessary to analyze Event logs of the TX and RX modules of the radio.

Every time the radio restarts (or is powered up), it stores the restart-related events in the event logs at a certain point of booting process:

001 RESTART – indication of radio restart

110 MMI PART a b c – indication of MMI booted partition

351 TX PART a b c – indication of TX booted partition (TX only)

439 RX PART a b c – indication of RX booted partition (RX only)


6166.5368.02.01 4.24

The following table shows restart triggers (referenced shortly as “triggers”)

and the related events in the event log. The restart-related events described above are not part of the table. Please note that some triggers do not create an event in the event log. The disjunctive method can be used for detection of such triggers.

5.1.1 TCXO Adjustment

TCXO adjustment Due to the natural aging of the crystal oscillator (TCXO), it is advisable to check the frequency offset after the first year of operation and readjust it if necessary. We recommend a further adjustment interval of 3 years in order to ensure the specified frequency accuracy.

Test connection

Fig. 5.1 Test connection of TCXO adjustment.

Test procedure

DUT is controlled via the R&S ZS 4200 (see chapter 3.3).

The minimum warm-up time is 1 minute for the TCXO.

Test frequency: 120 MHz (see chapter 3.4.7.2)

Power level set: Low (see chapter 3.4.7.2)

Mode: AM (see chapter 3.4.7.2)

Radio is keyed ON, e.g. via function Test PTT, which delivers an unmodulated CW signal (see chapter 3.4.7.4.1).

Measure frequency at antenna X3 and adjust TCXO value using the Service & Maintenance Tool R&S ZS 4200 (see chapter 3.3).

The step width (1 bit) for the adjustment is approximately 11 Hz. Adjust it only in small steps and do not detune the TCXO to the extreme positions, because the internal reference on the RF module could unlock here. (CBIT error 0315, see chapter 4.2.1).

5.1.2 OCXO Adjustment (Optional)

OCXO adjustment Due to the natural aging of the crystal oscillator (OCXO), it is advisable to check the frequency offset after the first year of operation and readjust it if necessary. We recommend a further adjustment interval of 3 years in order to ensure the specified frequency accuracy.

Note: If the radio is started at low temperatures (approximately −20 °C), the frequency of the OCXO is far from its nominal value. This causes the generation of the CBIT message 0315 TX INT REF UNLOCK. When the OCXO is warmed up, this message will disappear. This is a typical behavior of radios with the OCXO installed and not an indication of a radio failure.

Test connection

Fig. 5.2 Test connection of OCXO adjustment.

Test procedure

DUT is controlled via the R&S ZS 4200 (see chapter 3.3).

The minimum warm-up time is 10 minutes for the OCXO. The OCXO OVEN WARNING must disappear before the OCXO can be adjusted.

Test frequency: 120 MHz (see chapter 3.4.7.2)

Power level set: Low (see chapter 3.4.7.2)

Mode: AM (see chapter 3.4.7.2)

Radio is keyed ON, e.g. via function Test PTT, which delivers an unmodulated CW signal (see chapter 3.4.7.4.1).

Measure frequency at antenna X3 and adjust OCXO value using the Service & Maintenance Tool R&S ZS 4200 (see chapter 3.3).

The step width (1 bit) for the adjustment is approximately 1.5 Hz. Adjust it only in small steps and do not detune the OCXO to the extreme positions, because the internal reference on the RF module could unlock here (CBIT error 0108, see chapter 4.2.1).

5.2 Fan Maintenance Fan Maintenance\Fan Maintenance "Radio".doc

Introduction The main fan of the radio prevents the radio from overheating in case of high external temperature, or a high VSWR value on the transmitter. The fan of the PSU (power supply unit) ensures that the power supply does not overheat. Therefore, the temperature inside the radio is constantly measured and the rotation speed of the fans is adapted accordingly and monitored.

Inspecting the air intake

Inspect the air intake on the front panel for dust build-up and clean it if necessary. The inspection interval depends on the environmental conditions under which the transceiver is operated.

Note: Due to the long service life of the fan, no regular maintenance is required here besides cleaning. The speed of the fan is monitored by means of the continuous built-in test (CBIT), and a warning is promptly generated (see chapter 4.2).

Maintenance of the main and PSU fans

If a fan wears out, it is recommended to exchange the fan to prevent the radio from subsequent failure. An indication to replace the fan is the occurrence of a CBIT warning message. If a “warning” occurs, the radio is still operational, but the fan must be replaced soon.

If one of the following CBIT messages occur more than once or over a prolonged period of time, it is recommended to replace the main fan or the PSU fan as a preventive action.

On the transmitter:

0103 MAIN FAN WARNING, possibly in conjunction with a temperature warning 0317 PA TEMP WARNING or 0319 TX TEMP WARNING

0201 PSU FAN WARNING, possibly in conjunction with a temperature warning 0203 PSU TEMP WARNING

On the receiver:

0103 MAIN FAN WARNING, possibly in conjunction with a temperature warning 0411 RX TEMP WARNING

0201 PSU FAN WARNING, possibly in conjunction with a temperature warning 0203 PSU TEMP WARNING

Replacement of the fan is described in the service manuals of the radios, where also the order number for the spare part is listed.
