Rhode and Schwarz FSVA3004 Spectrum Analyzer

The Rohde & Schwarz FSVA3004 is a spectrum analyzer delivering signal characterization across 10 Hz to 4 GHz (standard) with optional extension to 2 Hz. Purpose-built for research, development, and production environments, it combines rapid measurement speed with extensive analysis capability. The instrument supports analysis bandwidths up to 1 GHz, with standard RBW options from 1 Hz to 10 MHz.

Extended bandwidth configurations via the R&S®FSV3-B8E option provide 20 MHz, 28 MHz, and 40 MHz RBWs.
