The Agilent/Keysight 84801A is a coaxial power sensor engineered for precise RF and microwave power measurements from 10 MHz to 18 GHz. This thermocouple or diode-based sensor delivers measurement capability across a -70 to +20 dBm power range and integrates directly with Keysight power meters via Type-N connector. Calibration factor data stored in the sensor’s EEPROM auto-downloads to eliminate manual entry errors. Low SWR design minimizes mismatch uncertainty. Dual-range power architecture provides enhanced sensitivity to signal fluctuations.
