Rohde & Schwarz FSU43 High Dynamic Range Spectrum Analyzer 43 GHz with 1 Hz RBW and +25 dBm TOI
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 characterizing Ku- and Ka-band devices.
Its 1 Hz - 50 MHz RBW suite and wide +25 dBm TOI provide 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 maintain stringent EVM/ACLR limits.
Fresh calibration, current firmware and ready-to-ship inventory enable immediate deployment with significant capital savings compared to new microwave analyzers—without compromising measurement precision, remote-control automation or long-term serviceability.
