Broadband Cable Analysis Measuring System MSK 33 /

MVG

A few functions such as „Clear display,“ „Printout the spectrum“ (prt

123)and switch-over functions can be remotely controlled via the MVG 10. Refer to the operating manual MVG 10!

Upstream measurement

The MVG 10 (1) wobbulates in free frequency ranges in the return path.

The MSK 33 (1) receives the signals in the MVG 10 tracking mode. The graphic of the MSK 33 (1) is given to the MVG 10 via a SCART cable in RGB (60 Hz) and transmitted to the MSK 33 (2) on a free downstream channel (attention two-sided band modulation!).

With the aid of the print command „Prt 999“ on the MVG 10 (1), the spectrum can be printed out on the head station from the MSK 33 (1). The command „Clear“ clears the spectrum representation on the MSK 33 (1).

Downstream measurement

Preparation

First, the signal generator with external RGB modulation must be stored on the memory posi- tion „0“ of the MVG 10 (2) and the channel sweeper with the desired channel sweep ranges must be stored on the memory position „1.“

With the command „Fkt A 1“ from the MVG 10 (1), the MVG 10 (2) s switched over via the MSK 33 (1) from the signal generator mode to the downstream sweep generator mode.

The MVG 10 (2) wobbulates the forward path in free frequency ranges.

The MSK33 (2) receives the signals in MVG 10 tracking mode.

With the command „Fkt A 0“ from the MVG 10 (1), the MVG 10 (2) can be reset into the signal generator mode. This occurs via the switching voltage of the SCART line.

Uscart = 12 V produces Recall no. 1 on MVG 10. Uscart = 0 V produces Recall Nr. 0 on MVG 10
