High Dynamic Range Spectrum Analyzer 43 GHz Rohde & Schwarz FSU43

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.

• Laboratory-Verified Performance: Every unit ships with an ISO/IEC 17025 calibration certificate bearing the TESTRO Certified seal, so you know the specifications are not just claimed—they're proven.
• Total Transparency: High-resolution teardown photos and a live video test session let you inspect seals, modules, and real-time performance metrics before you pay.
