General Purpose RF Spectrum Analyzer 3 GHz Used Rohde & Schwarz FSP3

The pre-owned Rohde & Schwarz FSP3 delivers laboratory-grade spectrum analysis across 9 kHz to 3 GHz in a portable form factor. Selectable 10 Hz-to-10 MHz resolution bandwidths and a low –106 dBc/Hz phase-noise floor at 10 kHz offset ensure clean ACPR, EVM and spur measurements for both narrow-band transceivers and broadband modulations.

Activating the optional 20 dB pre-amplifier extends sensitivity to –152 dBm, making the unit ideal for EMI debugging and low-level signal hunting. Supplied freshly calibrated with current firmware and standard GPIB/LAN/USB control, this second-hand analyzer offers immediate deployment and significant capital savings without compromising precision or long-term serviceability.

Industry Background & Resource Sourcing

Over the past two decades, rapid advances in China’s radio-frequency sector have shortened production-line refresh cycles to roughly 3–5 years. Leveraging long-term partnerships with equipment OEMs, research institutes, and calibration labs, TESTRO acquires traceable, well-maintained decommissioned or replacement units. Every instrument undergoes a five-step technical check and third-party calibration before entering stock, ensuring reliable performance data.
