The pre-owned Rohde & Schwarz FSUP26 unites a low-noise phase-noise tester and high-dynamic-range spectrum analyzer in one 4 kg enclosure. Fundamental mixing provides direct coverage from 20 Hz to 26.5 GHz, while an internal PLL and optional cross-correlation engine drive phase-noise floors below –177 dBc/Hz—ideal for crystal, PLL and DRO characterisation. Built-in low-noise DC supply and tuning ports accelerate VCO and synthesiser evaluation, and selectable 10 Hz – 10 MHz RBWs plus preselection filters ensure CISPR-grade spur analysis.

Delivered fully tested, freshly calibrated and firmware-current, this second-hand FSUP26 offers immediate availability and substantial cost savings versus new signal-source analyzers without sacrificing the precision, reliability or LAN/GPIB automation expected of Rohde & Schwarz instruments.

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.
