The pre-owned R&S FSW85 delivers fundamental-mixing spectrum and signal analysis from 2 Hz to 85 GHz, eliminating external harmonic-mixer complexity for mm-wave applications. Optional analysis paths provide up to 2 GHz instantaneous capture—and up to 8.3 GHz with the B8001 upgrade—while an ultra-low phase-noise floor of roughly −140 dBc/Hz at 10 kHz offset preserves EVM and ACLR accuracy. A displayed average noise level of −156 dBm (or −169 dBm with the B24 preamplifier) reveals faint spurs, and real-time processing up to 800 MHz accelerates dynamic-spectrum monitoring. Supplied fully tested, freshly calibrated and firmware-current, this second-hand unit ships immediately, offering substantial CAPEX relief without compromising Rohde & Schwarz reliability or automation interfaces.
