The Agilent/Keysight 8482H is a thermocouple power sensor for RF power measurement from 100 kHz to 4.2 GHz. It delivers high accuracy and stability across a measurement range of -10 dBm to +35 dBm (100 µW to 3 W) with exceptional low SWR that minimizes mismatch-related measurement uncertainty. The sensor features a Type-N male connector and 50 ohm impedance.
