The pre-owned Agilent N5181A MXG delivers crystal-clean CW and flexible analog modulation from 100 kHz to 6 GHz in a single 3-U chassis. Its –123 dBc/Hz phase-noise floor protects mixer and receiver margins, while the electronic step attenuator provides a calibrated +24 dBm to –144 dBm span—wide enough for PA compression, sensitivity and EMC immunity testing without external pads.

Built-in AM, FM, phase and pulse modulation plus list and step sweeps speed device characterisation, and full SCPI/LAN/GPIB control drops straight into automated benches. Refurbished units ship ISO-17025-calibrated with current firmware, trimming capital cost and lead-time yet preserving Keysight-grade reliability and future option paths.

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.
