Supplied pre-owned and freshly calibrated, the FSUP8 merges a metrology-grade phase-noise tester with a high-dynamic-range spectrum analyzer covering 20 Hz to 8 GHz. Its internal PLL and optional cross-correlation engine push sensitivity to –165 dBc/Hz at 1 MHz offset, making it ideal for OCXO, PLL and DRO characterization, while 1 Hz–50 MHz RBWs and built-in preselection support classic spur hunting and EMI scans. LAN, USB and GPIB automation plus field-installable 20 dB pre-amplifier and LO/IF ports future-proof the platform.

Immediate availability and significant savings over new signal-source analyzers deliver fast, reliable calibration-lab performance without compromising Rohde & Schwarz precision.

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.
