Description of functions

With the system ZDS94/VTZ98; ZDS94/VTZ94 it is possible to bypass 1500m and 2800m respectively

over a symmetric twisted pair line, e.g. (A-2Y(L)2Y4x2x0.8).

Thanks to system equalisation of up to 40 dB and 60 dB respectively at 5 MHz, droop, active black-level clamping, low pass filter, synchronous pulse control and Sync-Burst-Regeneration, a proper transmission of images is provided.

On the emission side (ZDS94), a 6 dB/12 dB increase can be adjusted at 5 MHz. Thus a higher signal/noise ratio can be achieved.

The transmission end levels are electrically isolated from the transmission line by transmitters. Thus a high electrical strength is achieved.

19” versions and weather proof versions are available.

The transmitter ZDS94 is a two channel component assembly.
