The HP/Agilent 8483A is a thermocouple-based power sensor for average RF and microwave power measurement from 100 kHz to 2 GHz. Operating across a dynamic range of −30 dBm to +20 dBm, this 75-ohm sensor delivers accurate readings suitable for component characterization, system validation, and production testing. The Type-N male connector and compact form factor enable integration into benchtop and automated test systems. A mechanical adapter (HP 1250-0597) permits connection to 50-ohm power meter reference connectors; impedance mismatch correction requires calibration adjustment.
