Agilent/Keysight ECP-18A

The Agilent/Keysight ECP-18A is a diode power sensor for measuring average power in continuous wave (CW) signals across RF and microwave frequencies. Engineered for engineers, system integrators, and laboratories, it delivers accurate power characterization with a 90 dB dynamic range and excellent SWR performance to minimize mismatch uncertainty.

Technical Specifications

• Frequency Range: 10 MHz to 18 GHz


• Power Range: −70 dBm to +20 dBm


• Dynamic Range: 90 dB


• Connector: Type-N (m)


• Measurement Type: Average power (CW signals)


• Measurement Speed: Up to 400 readings per second (with E4416A power meter)

Key Features

• EEPROM-stored calibration factors with linearity and temperature compensation data for error correction


• Low SWR design reduces source and sensor mismatch errors


• NIST-traceable calibration and traceability


• Fast GPIB measurement capability

Typical Applications

• RF and microwave signal power characterization


• CW signal measurement and validation


• Laboratory and production power verification


• System integration and test environments
