The R&S SFU broadcast test system is a multistandard signal generator that is used worldwide. It provides a platform that supports all conventional TV and audio broadcasting standards and is used as a reference signal source. This all-in-one compact solution combines many applications in a single instrument of only four height units. The R&S SFU offers unique features in the RF band and the baseband, in channel simulation and interferer generation, plus a powerful fading simulator and a variety of noise sources. Due to its modular design and flexible option concept, the R&S SFU can be optimally adapted to the requirements of different applications. It is an ideal research and development tool for improving established standards and generating new standard signals.
