The pre-owned Rohde & Schwarz FSW43 provides laboratory-grade spectrum and vector-signal analysis from 2 Hz to 43.5 GHz without the complexity of external harmonic mixers. Optional 2 GHz--and even 8.3 GHz--instantaneous capture allows one-sweep characterization of 5G FR2, broadband radar and satellite links, while a -136 dBc/Hz phase-noise floor and -156 dBm sensitivity reveal spurs that threaten tight EVM and ACLR budgets. Field-installable 30 dB pre-amplifier, LO/IF break-outs and real-time bandwidth keys future-proof the platform for dynamic-spectrum monitoring.
Units are supplied fully tested, freshly calibrated and firmware-current, delivering immediate deployment and substantial capital savings over new hardware without compromising Rohde & Schwarz precision or automation readiness.
