The Rohde & Schwarz SFC Compact Modulator is a multi-standard signal source for generating modulated signals across terrestrial, cable, satellite, and audio broadcasting standards. It delivers high-precision modulation with MER greater than 40 dB, supporting both digital and analog TV formats alongside DAB, DAB+, and FM/RDS audio. The instrument operates as a standalone unit with integrated transport stream playback and analog audio/video generation, or integrates into production test systems via ASI input and optional digital I/Q connectivity. Its ½ 19″ rack width and 1 HU height enable efficient rack deployment with minimal thermal footprint.
