The pre-owned Keysight N9000A CXA brings affordable spectrum and vector-signal analysis from 10 Hz up to 26.5 GHz to R&D benches and production lines. A 140 MHz optional capture path allows single-sweep EVM, ACPR and spur checks on LTE, Wi-Fi 6E and radar signals, while a –106 dBc/Hz phase-noise floor and –165 dBm displayed noise level expose emissions that threaten regulatory-limit margins. Touch-friendly front panel, SCPI automation over LAN/GPIB and field-installable measurement apps streamline debug and calibration tasks.

Supplied fully tested, freshly calibrated and firmware-current, each unit offers immediate deployment and substantial CAPEX savings versus new hardware—without compromising Keysight accuracy 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.
