Rohde & Schwarz FSV7 10Hz to 10GHz Signal and Spectrum Analyzer

The Rohde & Schwarz FSV7 is a signal and spectrum analyzer engineered for demanding RF measurement tasks in development, production, and service environments. Operating from 10 Hz to 7 GHz (DC-coupled), it delivers excellent RF performance with 0.01 Hz frequency resolution and marker resolution of 1 Hz. The analyzer supports analysis bandwidths up to 40 MHz (standard), with optional expansion to 160 MHz via the R&S®FSV-B160 module.

Level measurement uncertainty remains tight at 0.4 dB across the full 7 GHz range.
