Description of functions

With the ZDS94/VTZ05W system 2800m can be bypassed by symmetric twisted-pair lines, e.g. (A-2Y(L)2Y4x2x0.8).

The equaliser can also be installed as coaxial cable equaliser (BNC input). The input impedance can be switched to 75 Ω.

Up to seven field lengths of 1800m each can be bypassed (12600m) due to system equalisation up to 60 dB at 5 MHz, droop, active black-level clamping, low pass filter, synchronous pulse control. 

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

Due to separate and active equalising filters only those frequencies which are allocated to the respective adjuster are modified during balancing.

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