The pre-owned Agilent N8487A extends average-power measurements from 50 MHz to 50 GHz, letting a single sensor cover Ku- through V-band radios, mixers and waveguide components. Its wide –35 dBm to +20 dBm span and < 1 % linearity reveal true gain, compression and flatness without range-switch glitches, and the thermocouple architecture delivers genuine RMS readings on any modulation format. EEPROM-stored cal factors eliminate manual entry, so pairing with modern EPM, P-series or N191x meters yields instant, low-uncertainty results.
Refurbished probes ship ISO-17025-calibrated, trimming capital cost and lead-time yet preserving Keysight accuracy, firmware support and rugged 2.4 mm connectivity for long-term serviceability.
