The Rohde & Schwarz SFE100 is a highly compact, single-standard test transmitter and signal generator featuring realtime coding for a comprehensive range of digital and analog broadcasting standards. Occupying only 1 HU, it integrates a baseband signal source (such as a transport stream player or audio/video generator) and an optional arbitrary waveform generator, making it highly versatile and efficient for production test systems and laboratory environments.
