Why Sweep is the Right Solution
The majority of all transmissionerrors (including digital) arefound by measuring the fre-
quency response of the network. Every
physical error in the network that influ-ences the transmitted signals will berevealed in the sweep trace. This meansthe sweep results are independent oftransmission methods and formats.
The goal is to transmit all signals with thebest noise specifications and the lowestintermodulation distortion. Sweep is themost effective and efficient tool to showthe best compromise between the two. Inother words, sweep helps you to setup theright gain versus frequency.
Normalized Sweep. To ensure that networkspecifications are maintained, starting fromthe headend to the subscriber, each sectionof the network has its own set of specifica-tions. A normalized sweep divides the net-work into easy manageable sections. Eachnetwork section can be designated to an indi-vidual team or contractor, with its own set ofspecifications and quality requirements.
! Forward sweep display revealing severe problems at the low frequency end.
The SDA series uses a variation of the orig-inal Stealth Sweep technology. Existingvideo carriers (analog, digital, or scram-bled) are referenced when possible, elimi-nating any possibility of interference to thesubscriber services. Where carriers areabsent, the SDA-5500 Transceiver at theheadend transmits a sweep to fill vacantspectrum areas. To remove effects of head-end level drift, the SDA-5500 Transceivermonitors the levels and transmits new ref-erence information with every sweep. Thismeans if the signal levels are changing inthe headend, they won't effect the sweepresponse measurement. The SDA-5500Transceiver has all of the measurementcapability of the SDA-5000 Receiver, there-fore the Headend Technician can keep aneye on headend levels.

The SDA series also offers significantlyfaster forward sweep speed, especially insystems that include many digital signals.The SDA is capable of referencing 64/256QAM signal types, so there is no need toworry about subscriber interference orinjecting sweep carriers in the guard bands.
Stealth Sweep and SDA Series SweepCompatibility. The SDA series is com-pletely sweep compatible with Stealth3SR, 3ST, 3HRV and StealthTrak SSA-1000series meters. The only requirement isthat firmware version 9.3 is installed inStealth Meters, and firmware version 2.0installed in StealthTrak SSA-1000 meters.Additionally, in order to take full advan-tage of the faster forward sweep capabili-ty, all headend and field instruments mustbe SDA series.
Preparing the Network for Interactive Services Reverse Sweep. The SDA-5000 (with OPT1 installed) allows simple and practicaltesting of the reverse path frequencyresponse, regardless of the frequency (5to 1,000 MHz). And the SDA has a built-inreverse sweep transmitter, which meansexternally generated carriers are notrequired. Furthermore, the SDA-5500transmitter and field receivers have fre-quency agile telemetry. They can be con-figured to communicate on both the for-ward and reverse paths.
Forward (downstream) and reverse(upstream) path alignment can be done
simultaneously by one person. The operatorsimply indicates which screen he wants tosee—the response from the headend to thetest point, or the response from the testpoint to the headend. A reverse sweep canuncover mismatch problems, which revealthemselves as standing waves, or diplex fil-ter roll-offs that can severely hamper thequality of services in the reverse band.
Multiple User Reverse Testing. Forintense reverse testing requirements, therack mounted Model SDA-5510 HeadendReverse Sweep Manager handles thereverse sweep job for up to ten differenttechnicians on the same cluster of nodes.Using the SDA-5510 in conjunction withthe model SDA-5500 Transceiver provides afull forward and reverse sweep alignmentsolution. The SDA-5510 can also standalone in remote hub-sites for dedicatedreverse alignment applications.
Portable Reverse Sweep Manager. Theportable version of the SDA-5510 allowstechnicians to install a multiple userReverse Sweep Manager in locationswhere it is not practical to install a rackmount unit. The SDA-5000 with OPT 6provides all the functionality of the SDA-5510, but in the rugged SDA-5000 fieldunit package. Applications include instal-lation in systems where reverse traffic isreceived by an ATM/SONET/SDH networkrather than returning to the headend, orany condition that prevents rack mountinstallation or access to a headend/hub-site (Note: Forward sweep capability notincluded with SDA-5000 with OPT 6).
SDA instruments providea comprehensive set ofmeasurement tools that
will follow the expansionof your cable network.
!
Seeing Headend/Hub-Site AccumulatedIngress in the Field. The reverse noisefeature of the SDA-5000 enables easyreverse path noise testing. The operatorsimply presses the "Noise" soft key whilereverse sweeping, and the display changesto a noise/ingress response indicating thenoise level over the entire reverse pathspectrum measured at the headend orhub-site. All SDA transmitters providefeedback to the field regarding the currentcondition of noise and ingress in the head-end, even when noise or ingress is"swamping" the telemetry (broadcastmode). A "picture" of the headendnoise/ingress is sent out to the receiver viaa special forward telemetry carrier.
! Reverse ingress spectrum display.
QAM View Ensures Quality Forward Path Digital Services. For measurement andanalysis of digital TV and forward modemsignals, the new digital QAM View optionprovides a full complement of digital quali-ty measurements. Included is a 64/256QAM constellation display with zoom,average digital power level, Bit Error Rate(BER), 21 to 35 dB Modulation Error Ratio(MER) and noise margin "cliff effect" para-meter. An equalizer display shows equaliz-er stress and distance to fault.
! Constellation display with MER andpre/post FEC BER.
In addition, an exclusive noise mode allowstechnicians to see ingress/noise under anactive digital carrier. This tool is invaluablefor detecting forward path ingress otherwisehidden by conventional spectrum views!
! QAM ingress feature shows noise/ingressunder an active carrier.
Measuring the Behavior of DOCSISCompatible Cable Modem Signals in theCable Plant. For "bursty" digital signals,such as TDMA technologies used on cablemodems for reverse services, the SDA-5000uses the advanced Zero Span capabilitiesto make the measurement. Time domaindisplays of TDMA signals allow power mea-surement, D/U (desired/undesired mea-surements), and detection of packet colli-sions, all while the modem is in service.Technicians can measure the level of inter-ference in the actual channel being used.
! Reverse digital modem signal.
! Cable modem analysis using Zero Spanmode provides accurate, in-service, powerand C/N Measurements.
"One Box" Solution
How many test instru-ments should the networkmaintenance techniciancarry? One. A lightweight,rugged and affordablemeter with the versatilityto test the latest digitalservices while maintainingthe analog spectrum. This"One Box" philosophyshaped the design of theSDA series, adding theanalog and digital testtools most requested byfield technicians and system operators throughout the world.

Analysis with MER, Pre/Post FEC BER,Constellation, andExclusive Noise / IngressUnder the Carrier Measurement
Detecting Ingress in the Field.The operator looks at theingress present at the field test
point using the spectrum display on any ofthe receivers, then switches to reverseingress/noise to see the ingress at theheadend for comparison. This time-savingprocedure helps in locating sources ofingress. An adjustable dwell time ensuresthat even intermittent ingress is detected.The pre-amp and low-pass filter alsoassures that even low-level ingress is seen.The pre-amp and low-pass filter on theSDA-5000 assures that ingress can be mea-sured on devices with bi-directional test-points or testpoint values of 30dB or more.
! Time domain view of ingress in the ZeroSpan mode captures elusive ingress.
PathTrak Field View. Whenyour system is equipped withthe PathTrak Performance
Monitoring System, system technicians canbenefit from the ultimate ingress fightingtool—the PathTrak Field View option forthe SDA-5000. With Field View, The SDA-5000 receives a return path headend spec-trum broadcast from the PathTrak unit, andthen compares it with a return path spec-trum at any field testpoint. The side-by-side spectrum comparison instantly revealsto the technician whether the ingresssource is originating at his current test-point or at a different location. The com-parative spectrum technique slashesnoise/ingress troubleshooting time, since
the technician can immediately verifywhether corrective action performed in thefield (local trace) results in improvement inthe headend spectrum (remote trace).
! PathTrak Field View option comparesheadend node spectrum with field test-point spectrum.
Powerful Graphic Displays and Common User Interface AllowsTechnicians to Learn Fast
The results of all measurementsare presented to the user inclear, highly informative, sum-
mary displays. The graphics present theinformation the way the technician wantsto see the results – no further interpreta-tion required. For example, testpoint com-pensation values are entered at the start oftesting. Displays then calculate actual lev-els automatically, minimizing field errors.
! Graphical reverse testpoint compensation.
With SDA series products, all levels ofinstruments are familiar to the technician,regardless of which is learned first,because the same user interface conven-tions are used across all product families(several examples of the icons are includedin this literature). The learning curve for aprogressing technician is considerablyshorter than alternative test equipment.This means urgent upgrade projects makethe most efficient use of limited resourceswhen SDA series products are used.
! The Navigator user interface, common onall WWG meters.
Comprehensive Testing The SDA provides an extensive set of sig-nal analysis features designed for proving,and improving, network quality. All testsutilize a practical user interface, normallyrequiring only a one-button keystroke.
Level Measurement. The SDAinstruments provide a compre-hensive single-channel display
with tuned channel, video frequency andlevel, audio frequency and level, and thedifference between video and audio carrierlevels.
! The single-channel level display showsboth video and audio levels (either single ordual sound/NICAM) and the differencebetween the two.
! Digital channel average power measurementscan be made using the digiCheck™ feature.
Making accurate digital average powermeasurements are addressed with thedigiCheck™ measurement function. ThedigiCheck™ feature is compatible withmost "non-bursty" digital modulations inuse today (i.e., 16, 32, 64, and 256 QAM,QPR, QPSK, VSB, CAP16, etc.).
Analog and Digital Signal Limits.Analog signal threshold limitshave always been a technician’s
favorite feature of WWG instruments.Automatic limit checks provide a quick go/no-go status for audio and video levels. The SDAseries extends this capability with a dedicateddigital limit set that can be applied exclusive-ly to the forward digital carriers defined in achannel plan. By assigning separate analogand digital limits, test time is reduced sinceno calculation is necessary to determine ifanalog and digital level relationships are with-in system specifications. Analog and digitallimit capability is available in both the scanand autotest modes (available July 2000).
Tilt Measurement. Tilt is theeasiest and most efficient toolfor balancing amplifiers. For
cable plants requiring multiple tilt mea-surements, such as comparing today’s tiltmeasurement with a historical record, andthen making an additional measurementfor a new wider channel plan, the user sim-ply uses markers to indicate the tilt chan-nels that define the new limits.
! Tilt mode performs automatic tilt calcula-tions between any 2 of 9 designated carriers.
The CTB/CSO mode is used forautomatically making intermod-ulation measurements.
Scan Measurement. Scan modeprovides a quick graphical view ofthe entire channel plan with bars
representing the video level for each chan-nel. Both video and audio may be displayed.

“Bootcamp”
! Limit checks can be instantly viewed afteridentifying channel of interest with a marker inscan mode display.
Carrier-to-Noise Measurement:In-Service. Carrier-to-noise mea-surement (on non-scrambled
channel) is just as easy, and there is no needto remove modulation from the video carri-er. No tunable preselector filter is needed.
! In-service carrier-to-noise.
Hum Measurement: In-Service.Measuring hum on a channel(non-scrambled) is as simple as
pressing the "HUM" key. And since theinstrument is battery powered, the measure-ment is independent of ground loops, there-fore isolated from the line (mains). Humreveals itself as either single (60 Hz) or dou-ble (120 Hz) horizontal bars across the videoscreen. The level of either can be measured.
! In-service HUM (PAL/NTSC compatible).
Modulation Measurement.Includes NTSC, PAL and SECAMformats. Demodulation of the
audio is done for both AM and FM. FM isused to hear audio distortion on the FMradio channels or the sound of the TV pro-gram. AM is used to recognize short-waveinterference signals in the reverse band.
! Depth of modulation.
Local Amplifier Alignment withLoopback Tests. The SDALoopback tests allow the techni-
cian to quickly perform frequency responsemeasurements of active or passive fielddevices using a single meter. Either a CWor sweep signal may be generated from theSDA unit and injected to the input of adevice under test. The DUT output canthen be measured by the SDA, providingvaluable information like gain, loss, roll-offor frequency response. The CW loopbacktest is available on the SDA-5000 whenordered with OPT 1. The CW loopback andSweep Loopback features are available onthe SDA-5000 when ordered with OPT 2.
! Local Loopback Sweep: Performs initialsetup of optical nodes or measuring the gainor loss of individual components in the field.
Extensive Automated Test Capability Automated tests can be scheduled to per-form either 24-hour FCC compliancetests, or initiated immediately to log per-formance at individual nodes, amplifiers,or other testpoints. A wide range of testscan be performed automatically, includ-ing signal levels, C/N, hum, and depth ofmodulation. The operator designateswhich tests to perform on which chan-nels. Because these tests are non-intru-sive, it is easy to test all parameters onall channels at anytime.
After a test is performed, the results can bedisplayed on the SDA screen. A pass/failindication on a variety of limits can be setfor FCC/CENELEC or other governmentstandards, or to system preferences. Datataken during any automated test, orsequence of automated tests, can beviewed immediately with a pass/fail indica-tion for each of the limits. Specific storedmeasurement results may be viewed ondemand. Automated test results can beprinted directly to a serial printer oruploaded to a PC using StealthWare tostore and include in custom reports.
! The detailed forward or reverse sweepgraph offers user-adjustable markers, scale,reference level, and tilt. Users can clearly dis-tinguish the difference between previous andcurrent sweep measurements for easy com-parison on the PC StealthWare display.
Data Analysis with StealthWare Any stored SDA measurement informationcan be up-loaded to a PC usingStealthWare, a Windows™ based data man-agement package. Stored sweep, scan, orspectrum screens can be viewed on the PCand analyzed with marker movement andreadout information just the same as on theactual unit. A sweep graph overlay functionallows comparison of multiple RF responsevariations over time. Old sweep graphs may
be downloaded back into the SDA instru-ment for real-time comparison.
StealthWare also allows the operator tobuild channel plans and edit site locations,which can be downloaded to multiple SDAinstruments. Additionally, channel planscan be uploaded to the PC, modified inStealthWare, and then downloaded back tothe SDA instrument.
