Professional Head-End Station Systems of the PSU series

These professional head-end station systems ensure optimum supply of network clusters with highly differing infrastructures. The remote control feature for this head-end stations ensures maximum convenience.
With the PRCU 8 intelligent remote control unit, all parameters can be set remotely with a connectable analogue or GSM modem, which also operates with a prepaid card. This allows extremely convenient reprogramming. With the professional cassettes, the output carriers can be switched on and off to activate redundant cassettes for service.
The special monitoring cassette PSCU 6000 also offers a further possibility of monitoring the entire head-end. Here, the entire frequency range from 47 MHz to 862 MHz is scanned continuously. This also allows signals to be monitored which cannot be converted in a PSU system. The level or synchronising pulse is monitored for analogue TV and radio stations. The bit error rate is evaluated for the digital channels.
If service is required, a fault message is transmitted automatically either via SMS and/or facsimile.
Moreover, an information channel can be fed into the wideband network over the PSCU 6000 monitoring cassette. All channel information, including RDS names for the radio stations are displayed to TV viewers with this feature. The names of radio stations without RDS information can be edited.
A specially developed modulator allows an S/N ratio (weighted) of 60 dB to be achieved with the professional system.
This increases the cascading capability of the line amplifier in the wideband network.
