The Keysight E1416A is a single-channel average power meter housed in a C-size, single-slot VXI module with message-based control for integrated ATE systems. It delivers fast, accurate power measurements across a broad dynamic range using the 8480 family of thermocouple and diode power sensors, plus the 11722A sensor. The instrument achieves ±0.02 dB or ±0.5% absolute accuracy with a 1.00 mW reference (50 MHz oscillator, ±0.7%, NIST-traceable) and operates from 100 kHz to 110 GHz depending on sensor selection.
