Agilent/Keysight E1416A

The Agilent/Keysight E1416A is a single-slot, C-size VXI message-based power meter module engineered for accurate average power measurements across RF and microwave frequencies. This single-channel instrument integrates directly into VXI-based test systems and accepts Agilent 8480 series thermocouple and diode power sensors, plus the 11722A sensor, enabling flexible power measurement from 100 kHz to 110 GHz.
