Rohde and Schwartz unveiled an array of new transmitters at NAB. The R&S Nx8300 UHF transmitter is an air cooled medium-power transmitter, whose digital output power is up to 1.8 in a single rack. The cooling concept offers six possibilities of air intake and greatly reduces energy by 15 percent. The transmitter supports ATSC standards as well as MediaFLO and A-VSB. A-VSB is the leading proposed standard for mobile broadcast TV. 

“A-VSB is a signal frequency network that will be significant in building a mobile broadcast network,” says Jack Cowper, Rhode and Schwartz President and COO. Rohde and Schwartz is part of the A-VSB Initiative includes members Samsung, MobiTV, Nokia Siemens Networks, and SES Americom. There are live demonstrations of the platform in the A-VSB booth at NAB (Booth 1539).’

Rohde and Schwartz announced a new medium power outdoor transmitter. The R&S NV8303VO has an output power of 900W and also has a cooling system. Its compact enclosure makes it a perfect transmitter for Mobile TV. “There is a migration to smaller transmitters,” says Cowper. The outdoor transmitter is available in June 2008. Rohde and Schwartz have a new array of transposers. The R&S XLx8000 transposer makes it possible to fill gaps or expand transmission areas.

Rohde and Schwartz also unveiled their new TV analyzer for MPEG-2.   The GUI of the R&S ETL TV analyzer makes it easy to use and several features speed up the operation. Users do not have to enter frequency or channel bandwidth for each measurement.
