Rohde & Schwarz added new VHF high-power transmitters family to its product line

Rohde & Schwarz has added new family of VHF high-power transmitters to its product line. The R&S Nx8500 family covers analog, digital and mobile TV and digital audio broadcasting. It can be used worldwide and upgraded for future standards such as DVB-T2.

The liquid-cooled transmitter family is designed for high transmit power in the VHF band III as is typically required for basic coverage in broadcasting networks. Besides analog television, the R&S Nx8500 transmitter family supports the DVB-T, ATSC, ISDB-T/ISDB-TB and DTMB digital TV standards. It is already prepared for the DVB-T successor standard, DVB-T2. In addition, the transmitters cover the T-DMB, DVB-H, MediaFLO and ATSC Mobile DTV mobile TV standards. For digital audio broadcasting with DAB(+), which is also part of the portfolio, the transmitters achieve an outstanding signal quality with a modulation error rate (MER) of up to 33 dB. R&S Nx8500 transmitters provide an output power up to 20 kW for analog TV and 7.8 kW for COFDM standards. The output power for ATSC is 11.5 kW and for DAB up to 8.0 kW.

Since the signal processing of the transmitters is software-based, network operators can respond to expansions of existing standards and integrate them into existing networks. Because the transmitters can be switched from analog to digital operation, network operators will find that the R&S Nx8500 transmitters are a safe investment.
