Broadband Cable Analysis Measuring System MSK 33 /MVG84Broadband Cable Analysis Measuring System MSK 33 / MVGThe broadband cable analysis system consists of the antennameasuring instrument MSK 33 (including return path option) and thesignal generator MVG 10.Both units function in the frequency range from 4.0 MHz to 860 MHz.It allows the measurement of cable systems in CATV range (down-stream) and in the return path range (upstream).The measurement can also be carried out in the supplied cable.The signal generator MVG 10 can wobbulate in many segmentranges, which means that ranges which are occupied can be lockedby the generator, thus allowing TV reception not to be disturbed.Therefore, before the measurement, make a frequency and level plan!The MVG 10 requires a bandwidth of ca. 500 kHz for transmitting thetelemetric data, which means, that the set frequency points must haveat least a distance of 250 kHz from the used signal on the cable sys-tem, provided the amplitudes of the used signal and MVG 10 signalare the same.Before each frequency change, the MVG 10 transmits the next recep-tion frequency to the MSK 33 via a telemetric signal. In occupiedranges, which must not be swept, the MSK 33 can carry on the meas-urements in the same raster with maximum scanning speed. Duringthis time, the MVG 10 pauses. The MSK 33 measures the transmittedlevel and represents in the spectrum. the measurement can be printedout via the built-in printer.Measuring principleMVG10 MSK33Report FRQa+1FRQa FRQaTransmittingrange RecordingReport FRQyFRQx FRQxTransmitting-free fastrange sweepReport FRQzFRQy FRQyTransmittingrange RecordingReport FRQaFRQz FRQzCATV systemupstreamordownstreamMVG10MSK33
