The pre-owned Agilent N8485A extends average-power measurements from 10 MHz up to 26.5 GHz in a single, rugged thermocouple sensor. A wide –35 dBm to +20 dBm span and better than ±1 % linearity reveal true gain, compression and flatness without range-switch glitches, while the RMS architecture delivers accurate results on any modulation format. Its built-in EEPROM stores calibration data that downloads automatically to modern Keysight power meters, cutting setup time and uncertainty budgets.

Refurbished units ship ISO-17025-calibrated and firmware-verified, giving you Keysight-grade accuracy and long-term serviceability at a fraction of new-sensor cost.
