4.2 GHz High Power Thermocouple Power Sensor Agilent 8482B

The pre-owned Agilent 8482B lets you measure average RF power from 100 kHz up to 4.2 GHz at levels as high as +44 dBm, so a single probe can characterise kilowatt radar drivers, high-power amplifiers and broadband EMI sources. Its true-RMS thermocouple element and low-SWR Type-N body deliver < ±1 % linearity without range-switch glitches, while built-in attenuation protects the sensor up to 25 W. Although EEPROM-free, it plugs straight into modern EPM, EPM-P and P-Series meters, as well as legacy 43x frames, preserving existing test code and accessories. Refurbished units ship ISO-17025-calibrated, giving you Keysight-grade accuracy, 25 W headroom 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.
