Safety notes Safety notes Validity of handbook This handbook is valid for MVG 10, order no.: 208 320. The following notes are important for operating the MVG 10 and should be observed under all circumstances. General safety notes The MVG 10 was developed and produced in compliance with the relevant harmonised guidelines, standards and additional technical specifications. The product is state-of-the-art and ensures the maximum level of safety.
Safety notes Safety notes Always observe the VDE safety regulations. Observe the maximum permissible signal feed-in level. Neither DC voltage nor low-frequency AC voltage may be applied to the RF port. Only use fuses with the same cut-out characteristics. The unit is live even when not connected. The unit may only be operated with all shielding covers fitted and when closed to prevent electromagnetic interference. Only use suitable shielded cable.
System description and usage 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.).

System description and usage The spectrum at the head-end can be printed out from the MSK 33 (1) using the print command "Prt 999" on the MVG 10 (1). The command "Clear" clears the spectrum presentation on the MSK 33 (1). Downstream measurement: The MVG 10 (2) is switched from signal generator mode to downstream sweep generator mode via the MSK 33 (1) using the command "Fkt A 1" on the MVG 10 (1). The MVG 10 (2) sweeps the forward path in the free frequency ranges.

Noise generator Noise generator The noise generator is used for measuring cable installations or sections of cable installations that are not yet occupied with programming. It generates a broadband noise to evaluate the frequency response in the range from 4 MHz to 1 GHz. The bandwidth can be set to 1 MHz or 7/8 MHz.
Signal generator Signal generator The signal generator is needed to transmit test signals and the screen view from the MSK 33 during "Comfortable Up/Downstream measurement" (see system description). In addition to an internal test picture of coloured bars it has an external modulation input (CVBS/RGB + sound) and is double-sideband modulated. The channels/frequencies and levels can be selected freely.

Sweep generator Sweep generator The sweep generator is used to sweep in 10 preset frequency ranges (measuring profiles). The profiles can be programmed to free ranges depending on the channel allocation in the cable network, so that measurement is possible without interrupting or interfering with programmes. The frequencies and levels can be selected freely. Only use the sweep generator on free channels so that programmes and services in the cable network are not interrupted.
