Agilent E4413A diode power sensor. Has a wide dynamic range and is designed for use with the Agilent E4418A/B and Agilent E4419A/B power meters for power measurements on CW signals from 50 MHz to 26.5 GHz. The Agilent E4413A power sensor provides extremely low SWR to minimize the source and sensor mismatch errors. Also, for comprehensive error correction, the calibration factors, linearity and temperature error-correction information are stored in EEPROM. The sensor''s power measurements are traceable to the U.S. National Institute of Standards and Technology (NIST).
