E4413A

Keysight Technologies (Agilent HP)Power Sensors

The Keysight (formerly Agilent/HP) E4413A is a CW power sensor designed for highly accurate average power measurements over a frequency range of 50 MHz to 26.5 GHz. It delivers a wide 90 dB dynamic range (-70 dBm to +20 dBm) and features integrated EEPROM to store calibration factors, linearity, and temperature compensation data. It is widely used for RF and microwave test applications requiring NIST-traceable accuracy and compatibility with EPM, EPM-P, and P-series power meters.
