The pre-owned Agilent E4405B ESA-E brings reliable microwave coverage from 9 kHz to 13.2 GHz to production lines and field service in a single 4-U chassis. Standard 1 kHz–5 MHz RBWs—sharpened to 1 Hz with Option 1DR—and a –101 dBc/Hz phase-noise floor resolve closely spaced signals, while the optional pre-amplifier lowers the noise floor to –167 dBm/Hz, exposing faint emissions without an external LNA. SCPI / IVI control, optional tracking generator and measurement personalities, plus LAN / GPIB interfaces simplify automation.

Buying refurbished slashes capital outlay and lead-time; units can ship ISO-17025-calibrated with verified firmware, preserving Agilent accuracy and long-term serviceability at a fraction of new-instrument cost.

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.
