Description of functions

With the system ZDS94W/VTZ98; ZDS94W/VTZ94 it is possible to bypass 1500m and 2800m respectively with a symmetric twisted pair line, e.g. (A-2Y(L)2Y4x2x0.8). 

Due 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 transfer of images is achieved.

Cable attenuation equalisation is provided by Sync-Level-Control.

On the emission side (ZDS94W), 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.

The ZDS94W2 (article number 500471) transmitter is a two-channel component assembly supplied in a weatherproof casing.

The ZDS94W4 (article number 500472) transmitter is a four-channel component assembly supplied in a weatherproof casing.

The ZDS94W (article number 500470) component assembly is a two-channel component assembly for enhancement supplied in the weatherproof casing of ZDS94W2 on ZDS94W4.
