The Rohde & Schwarz FSVR13 is a real-time spectrum analyzer spanning 10 Hz to 13.6 GHz, combining traditional signal analysis with advanced real-time capture and examination of transient and intermittent signals. The instrument delivers 250,000 spectra per second with gapless time-domain spectrum display, enabling engineers to detect and characterize every event across RF development, troubleshooting, and compliance workflows.
