Offered pre-owned, the FSW43 combines fundamental-mixing coverage from 2 Hz to 43.5 GHz with optional 2 GHz—and even 8.3 GHz—instantaneous capture, letting engineers characterise 5G FR2, wide-band radar and satellite links without external harmonic mixers.

A sub–136 dBc/Hz phase-noise floor and a –169 dBm noise level expose spurious tones that endanger tight EVM or ACLR budgets, while 30 dB pre-amplifier and 800 MHz real-time keys extend sensitivity and dynamic-spectrum monitoring.

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.
