The pre-owned Agilent 8487A extends average-power measurements from 50 MHz up to 50 GHz, delivering a broad –30 dBm to +20 dBm span with better than ±1 % linearity. Its true-RMS thermocouple element provides accurate readings on any modulation format without range-switch glitches, while the low-SWR 2.4 mm interface keeps mismatch uncertainty tight for millimetre-wave links. Although it predates EEPROM-equipped probes, the 8487A plugs directly into modern Keysight EPM, EPM-P and P-Series meters—as well as legacy 43x/436/437/438 frames—so you can preserve existing test code and accessories. Refurbished sensors ship ISO-17025-calibrated, giving you Keysight-grade accuracy, 50 GHz coverage and long-term serviceability at a fraction of new-sensor 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.
