HP/Agilent 8481H Power Sensor 10MHz-18GHz

The 8481H thermocouple power sensor is designed for use with the EPM series, EPM-P series, 70100A, E1416A and the 435A/B, 436A, 437A/B, and 438A power meters. It operates from 10 MHz to 18 GHz at levels from -10 to +35 dBm with exceptional accuracy and stability. The 8481H has extremely low SWR and is traceable to the U.S. National Institute of Standards and Technology (NIST). A calibration port is included with the above power meters for calibration with the power sensor. This calibration provides traceability to NIST, and it eliminates the uncertainties due to temperature changes and the variance in making measurements with different meter/sensor combinations.
