Introduction
1 Introduction This document describes how to perform an RF
characterisation of a v1.2 Bluetooth® wireless technology CSR
_äìÉ`çêÉ» module.
1.1 Bluetooth Module Set-up
_äìÉ`çêÉ
™ R
F Module C
haracterisation Test Procedures
CSR has a development board known as the Casira™. If this kit is
available, the Bluetooth module to be tested must be connected to
the Casira carrier board (see Figure 1.1) and then mated to the
Casira development board. The SPI, power and GND are the minimum
signals needed. If a host interface (i.e., USB, UART) is available,
this should be connected as well. If a Casira development kit is
not available, then the unit under test should provide access to
the following interfaces:
SPI (Serial Peripheral Interface) USB or UART Power and Ground
Appropriate level shifter RF I/O
Casira carrier board Signalling, PWR and GND cables
Antenna pig-tail Bluetooth Module
Figure 1.1: Bluetooth Module Connection to Casira Development
Board
An antenna pig-tail (i.e., coax stripped on one end with a
connector on the other end) also needs to be added if the module
has a printed antenna on the PCB or if there is no access to the
transmit port. Remove any series component to isolate the printed
antenna and add the pig-tail either to the radio-side pad of the
removed component or to the antenna test point, if available. The
ground of the pig-tail needs to be well attached to the module
ground either at the shell or by scraping away some solder mask to
expose a solid area of the ground plane. The insertion loss of the
antenna pig-tail should be accounted for in all measurements.

Introduction 1.2 Required Test Equipment
To perform these tests, a PC with CSR’s BlueSuite™ (PSTools,
BlueTest and BTCLI) installed is required. Also required is a
spectrum analyser (preferably with the Bluetooth personality), a
loopback tester (such as the Anritsu MT8850A/MT8852A, Agilent
E1852A/B, Agilent N4010A or R&S CMU200 with the Bluetooth
Option) and a Casira Test Development Board. Also useful is a
signal generator.
1.3 Miscellaneous Notes
_äìÉ`çêÉ
™ R
F Module C
haracterisation Test Procedures
For the test results, be sure to compensate for the loss of the
antenna pig-tail (approximately 0.5dB to 1dB) and the RF
cable/connector (approximately 1dB to 2dB) for a total system loss
of approximately 1.5dB to 3dB depending on accessories used. The
system loss should be added to all test results reported by any of
the test equipment utilised.
The Bluetooth module should be tested at a minimum of three
channels:
Channel 0 = 2402 MHz Channel 39 = 2441 MHz Channel 78 = 2480
MHz
When launching the various CSR software tools, be sure to select
the appropriate host transport for communication.

Test Set-up
2 Test Set-up 2.1 Hardware Configuration
Connect the Bluetooth module to the Casira board. On the Casira
motherboard, be sure the SPI cable and either USB or UART (Serial)
cable is connected to the PC running the software noted in section
1.2. Be sure to disconnect the USB cable from the Casira
motherboard if UART is the desired host interface. If both the USB
and UART cables are connected, only the USB interface will
work.

2.2.1 PSTool Set-up
Start PSTool with the following parameters.
Transport SPI BCCMD on Port LPT1
_äìÉ`çêÉ
™ R
F Module C
haracterisation Test Procedures
Uncheck the “Halt Chip on SPI access” box. The other listed
transports can be use if supported by the module, however SPI is
the most flexible.
Verify that the following parameters are set correctly.
PSKEY_HOST_INTERFACE (0x01F9) Note the interface; this will be
needed for BlueTest
PSKEY_BDADDR (0x0001) 0002-5B-01A2B9 (this will be different for
each device)
Crystal Freq (0x01FE) 3E80 (16 MHz; this will be different for
different modules)
USB Vendor ID (0x02BE) 0A12 (CSR module)
USB Product ID (0x02BF) 0001 (CSR module)
UART Baud Rate (0x01BE) Note the baud rate for use with
BlueTest
Close the PSTool software once the above parameters are set and
verified.
2.2.2 BlueTest Set-up
Start BlueTest with the following parameters.
Transport BCSP or any other supported transport Serial COM1 or
any other supported COM ports
Baud Rate Depends on baud rate set by Bluetooth module. Use
PSTools to determine baud rate first
If “Transport Active” and “Link Active” appear along with the HW
ID and FW version, then a successful connection to the Bluetooth
module has been achieved. If no connection has been established
(i.e., “Cannot find BlueCore” message), verify cable connection,
transport mode and baud rate are set correctly.
Leave BlueTest running to perform the RF characterisation.

RF Tests 3.3.2 Procedure
The above parameters will transmit DH1 packets containing PRBS9
(pseudorandom bit sequence of (29 -1)) data with either a +1 or -1
MHz offset. A CFG_TX_IF of +2 will offset the carrier by -1 MHz and
a setting of -2 will have a corresponding offset of +1 MHz.
Adjust the offset to achieve the lowest LO leakage. For Class 2
designs, LO leakage across the entire band should be less than
-24dBc (relative to the wanted signal) but up to -22dBc is
allowable. See Marker 1 amplitude delta example in Figure 3.3.

For a Class 2 device, the height of the sideband at ±62.5kHz
should be less than -4dBc. See Figure 3.4 for an example. If the
sideband is too high, this could be caused by VDD_VCO and/or the
balun supply, which could be fixed with layout, routing changes
and/or additional RF filtering.

RF Tests
3.5.2 Procedure
In BlueTest, start the BIT_ERR1 test and turn on the RF on the
signal generator. The BlueTest utility will constantly update the
bit error rate as the amplitude on the signal generator varies.
Adjust the amplitude on the signal generator until a bit error rate
of less than or equal to 0.1% is achieved. The maximum sensitivity
level should be in the range of -78dBm to -82dBm, depending on LO
frequency. Repeat for all three channels. Be sure to record the %
Bit Error in Current Cumulation value from BlueTest. Figure 3.5
shows an example. _äì
