Agilent/Keysight ECP-E18A

The Keysight ECP-E18A is a diode power sensor engineered for accurate average power measurements of continuous wave (CW) signals across a wide frequency range. Delivering a 90 dB dynamic range and supported by EEPROM-stored calibration factors, this sensor provides traceable measurements to NIST standards. It connects via Type-N male connector and integrates with multiple Keysight power meter platforms for both manual and remote GPIB control.
