The pre-owned Rohde & Schwarz FSU43 delivers laboratory-class spectrum analysis from 20 Hz up to 43 GHz, eliminating the need for external harmonic mixers when characterising Ku- and Ka-band devices .
Its 1 Hz–50 MHz RBW suite and wide +25 dBm TOI give more than 110 dB of usable dynamic range, while a –123 dBc/Hz phase-noise floor and –158 dBm sensitivity expose low-level spurs and keep stringent EVM/ACLR limits intact .
Fresh calibration, current firmware and ready-to-ship stock translate to immediate deployment and significant capital savings over new microwave analyzers—without compromising measurement precision, remote-control automation or long-term serviceability.
