VHF Transmitter Family R&S NM/NW7001
With Transmitter Family R&S NM/NW7001 Rohde & Schwarz has extended the generation of transmitters for medium power based on MOSFET transistors. These air-cooled transmitters are suitable for analog and digital TV (DVB-T or ATSC).
The transmitters consist of the following components:The VHF transmitter family is available for analog TV with powers of 250 W to 2 kW (combined) and for digital TV with powers of 200 W/300 W to 800 W/1200 W. The power amplifiers come as plug ins with a power of 500 W for analog TV or 200 W/300 W for digital TV. This means high flexibility regarding output power and redundancy. Each amplifier module has its own power supply.
The newly developed exciter is an unrivalled innovation since signal processing is digital for analog TV signals too. The difference between the variants for analog TV, DVB-T and ATSC is simply the encoder module. Retrofitting a transmitter from analog to digital TV is thus very simple.
In addition, the exciter is extremely compact which permits the integration of a second exciter and the associated automatic switchover unit in all transmitters. Standby systems like exciter standby, passive standby transmitter, exciter standby with active output stage standby and n+1 standby are available.
Moreover, the VHF Transmitter Family R&S NM/NW7001 offers a variety of options for remote control such as parallel interface, SNMP interface or the linkup via an integrated Web server.
