Description of functions

With the ZDS94/VTZ05D system, 1500 m can be bypassed by symmetric twisted pair lines, 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 transmission of images is achieved.

Cable attenuation equalisation is provided by Sync-Level-Control. The picture amplitude is not controlled. It should only be controlled by the camera.

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

19” versions and weather proof versions are available.
