The pre-owned R&S FSW85 delivers laboratory-class spectrum and vector-signal analysis from 2 Hz to 85 GHz, eliminating external harmonic mixers for Ku-, Ka- and V-band workflows.

Optional 2 GHz—and even 8.3 GHz—instantaneous capture plus an 800 MHz real-time engine enable single-sweep characterization of 5G FR2, ultra-wideband radar and satellite links. A –137 dBc/Hz phase-noise floor and –123 dBm DANL at the microwave tip reveal spurs that threaten tight EVM and ACLR margins, while field-installable 30 dB pre-amplifier, LO/IF break-outs and tracking-generator keys future-proof the platform.

Supplied fully tested, freshly calibrated and firmware-current, each unit ships from stock—delivering Rohde & Schwarz precision and LAN/GPIB automation at a fraction of new-instrument cost.
