Rohde and Schwarz FSV3004 Signal & Spectrum Analyzer, 4 GHz

The Rohde & Schwarz FSV3004 is a signal and spectrum analyzer engineered for signal analysis, research, development, and production across demanding wireless applications. Operating from 10 Hz to 4 GHz, it delivers comprehensive measurement capabilities with configurable analysis bandwidths up to 200 MHz, resolution bandwidths from 1 Hz to 10 MHz, and 1 Hz marker resolution. The instrument achieves a displayed average noise level of −151 dBm typical at 1 GHz (−165 dBm with optional preamp) and third-order intercept of 18 dBm at 1 GHz, making it suitable for both weak-signal detection and high-dynamic-range measurements.

SSB phase noise reaches −107 dBc at 10 kHz offset (1 GHz carrier), improving to −114 dBc with the R&S®FSV3-B710 option. Sweep times range from 1 µs to 16,000 s depending on span and mode, with accuracy of ±0.1% at zero span and ±3% for swept spans ≥10 Hz. The capacitive multi-touch WXGA display supports intuitive operation, while SCPI recording and event-based actions streamline test automation and signal debugging.
