The pre-owned R&S FSH20 combines a 9 kHz-to-20 GHz fundamental-mixing front end with 1 Hz-to-5 MHz resolution bandwidth filters, delivering laboratory-class measurements in a robust 3 kg handheld package. With the optional 20 dB pre-amplifier it reaches a –161 dBm noise floor, allowing on-site spur hunting and EMI diagnostics, while a typical +10 dBm TOI preserves dynamic range for high-power devices.

Built-in tracking-generator and VSWR-bridge options add scalar network and cable-fault capability, and USB/LAN connectivity streamlines remote logging or automated sweeps. Fully tested, freshly calibrated units ship from stock, offering immediate deployment and substantial cost savings versus new field analyzers without compromising Rohde & Schwarz precision or 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.
