Ultra Wideband Spectrum Analyzer 43 GHz Rohde & Schwarz R&S FSW43

Covering 2 Hz to 43.5 GHz, the pre-owned R&S FSW43 combines fundamental-mixing architecture with optional 2 GHz instantaneous capture to characterise 5G FR2, radar and satellite links without external mixers. A typical –136 dBc/Hz phase-noise floor and –156 dBm sensitivity unveil low-level spurs and preserve stringent EVM/ACLR margins, while real-time bandwidth keys up to 800 MHz speed spectrum-monitoring tasks. Supplied fully tested, freshly calibrated and loaded with current firmware, each unit ships from stock—delivering top-tier Rohde & Schwarz accuracy, automation via LAN/GPIB and significant capital savings compared with new hardware.
