The Rohde & Schwarz FSVA3004 is a signal and spectrum analyzer spanning 10 Hz to 4 GHz, engineered for wireless communications, component testing, and aerospace and defense applications. It delivers a standard analysis bandwidth of 28 MHz, expandable to 400 MHz, with resolution bandwidth tunable from 1 Hz to 10 MHz. The instrument combines a displayed average noise level of –153 dBm (typical) with third-order intercept performance of 20 dBm, enabling detection of weak signals and characterization of highly nonlinear devices. SSB phase noise reaches –120 dBc/Hz at 10 kHz offset with a 1 GHz carrier, improving to –127 dBc/Hz with the B710 option. Sweep time accuracy of ±0.1% (span = 0 Hz) and ±3% (span ≥ 10 Hz) supports both production and laboratory workflows. A multi-touch interface, high measurement speed, and marker resolution of 1 Hz enable rapid signal diagnostics.
