Rohde & Schwarz R&S FSU3 3.6 GHz High Dynamic Range Spectrum Analyzer RF Second Hand Spectrum Analyser

The pre-owned R&S FSU3 delivers laboratory-grade spectrum analysis from 20 Hz to 3.6 GHz without the cost or lead-time of current-generation hardware.

A wide 1 Hz–50 MHz RBW suite and a −128 dBc/Hz phase-noise floor keep ACPR, EVM and spur measurements clean, while the optional low-noise pre-amplifier drives sensitivity below −162 dBm for EMI debugging and low-power IoT work. Standard GPIB/RS-232 plus an upgradeable LAN port support automated sweeps, and fast DSP processing accelerates production throughput. Shipped fully tested, freshly calibrated and firmware-current, each unit offers immediate deployment and substantial capital savings without compromising Rohde & Schwarz precision or long-term serviceability.
