Columbia, MD (August 20, 2007)–Rohde & Schwarz has added new functions to its R&S SFU, the universal broadcast test system that generates test signals in accordance with important global digital TV standards. The additions include video and audio baseband generators for PAL, SECAM, NTSC, and the R&S ATV-video video test signal library.
Supplementary test methods in the automotive field are also now possible with the DAB, DRM and, soon, ISDB-Tsb options.
The R&S SFU is the leading test transmitter in analog TV, since real-time coders are now offered for the internationally used analog standards B/G, D/K, I, M/N, and L. The new internal video and audio baseband generator for PAL, SECAM, NTSC, together with the analog R&S ATV-video video test signal library, is used to provide signals. Thus, an additional external video signal source is usually not needed. External video and audio generators can also be connected.
Additional test methods with DAB and DRM test signals are now possible in the automotive field, making R&S SFU a universal source for the development of audio receivers in mobile receivers. The R&S SFU-K353 option, which incorporates a comprehensive test signal library, is now available for digital shortwave transmission DRM (digital radio mondiale). An enhancement will soon be available with the ISDB-Tsb standard.
The R&S SFU TV test platform is used for developing and testing new digital transmission methods in TV. It provides high-precision standard signals, permits signal modifications up to the system limit, and can insert defined errors. The R&S SFU can be upgraded to accommodate emerging standards at any time.
The unit combines a test transmitter, a signal generator/recorder for MPEG-2 transport streams, a fading simulator with up to 40 paths, a broadband digital AWGN noise source, plus an ARB generator in a single platform.
