The HP/Agilent 8482A is a thermocouple-based power sensor engineered for precision RF and microwave power measurement from 100 kHz to 4.2 GHz. Designed for laboratory and production environments, it delivers stable readings across a -30 dBm to +20 dBm dynamic range and supports peak power measurement up to 15 W. The sensor terminates in a Type-N male connector and operates at 50 Ω nominal impedance. Each unit is individually calibrated with NIST-traceable CAL FACTOR data, minimizing mismatch uncertainty and eliminating temperature-related measurement drift.
