The Rohde & Schwarz FSVR7 is a real-time spectrum analyzer combining signal analysis, spectrum analysis, and real-time monitoring in a single instrument. Operating from 10 Hz to 7 GHz, it delivers gapless spectrum capture with real-time RF bandwidth up to 40 MHz and processes 250,000 spectra per second. The 128 Msamples/s 16-bit A/D converter enables detection and characterization of transient and intermittent signals across demanding measurement scenarios.
