Transmitters for Use in ATSC-M/H Mobile/Handheld DTV
Mon, 11/10/2008 - 11:23am
Rohde & Schwarz introduces ATSC-M/H technology in its DTV transmitter product lines. The SX800 is a fully frequency agile exciter that is already used in the latest ATSC and NTSC air-cooled and liquid-cooled proprietary transmitter systems, as well as in transmitters from other manufacturers. It is also available as part of an exciter retrofit package to replace the exciter in existing transmitters of any manufacturer. All R&S DTV transmitters that use the SX800 exciter are ready to be switched to ATSC-M/H without hardware changes. At the same time, a multiplexer will be introduced that supports ATSC-M/H to complement the transmitter and exciter products. This will allow broadcasters to move to ATSC-M/H operation.
