System description and usage

The MVG 10 Video Sweep Generator is designed to selectively sweep and measure the forward path and return path of television cable installations without interfering with the connected subscribers. The required sweep ranges, channels and signal levels (36…100 dBµV) can be programmed step-by-step. The channels can be set to various standards (e.g. B/G etc.).

Frequency ranges that are in use must be left out so that the subscriber reception is not disrupted.

Make a frequency and signal level plan before performing the measurement!

Before each frequency change, the MVG 10 transmits the next reception frequency to the MSK 33 with a telemetric signal. In ranges that are in use and which may not be sweeped, the MSK 33 can, as an option, continue measurement in the same channel plan at maximum scan speed. The MVG 10 pauses during this period.

The MSK measures the signal levels transmitted and presents them in the spectrum. The measurement can also be printed out with the integrated printer.

Return path measurement

The MVG 10 is also suitable for measuring the return path – terminal outlet to head-end – in the frequency range 4.0 MHz…80MHz.

For this, the MSK 33 must be equipped with the return path option.

The MVG 10 Video Sweep Generator must be modulated with a video signal.

Although measurement can be performed in cables that are in use, the ranges that are in use may not be sweeped. In addition, the MVG 10 signal generator can sweep in several partial ranges i.e. ranges that are in use can be left out by the sweep generator so that TV reception is not interrupted. The MVG 10 sweep generator informs the MSK 33 of the next respective reception frequency over the RF channel.
