The pre-owned R&S FSW50 couples fundamental-mixing coverage from 2 Hz to 50 GHz with optional 2 GHz—and even 8.3 GHz—instantaneous capture, eliminating external harmonic mixers for 5 G FR2, broadband radar and satellite payload tests.
An ultra-low –137 dBc/Hz phase-noise floor and pre-amp-assisted –164 dBm sensitivity expose spurs that jeopardize tight EVM and ACLR budgets, while high-speed LAN/GPIB control, touchscreen GUI and field-installable tracking-generator and real-time keys accelerate production alignment and EMI debugging.
Delivered fully tested, freshly calibrated and firmware-current, this second-hand unit ships from stock, offering immediate deployment and substantial capital savings without compromising Rohde & Schwarz precision or long-term serviceability.
