Agilent/Keysight E9321A

The Keysight E9321A is a peak and average power sensor engineered for RF and microwave measurements across wireless communications and radar applications. It operates from 50 MHz to 6 GHz and connects directly to Keysight EPM-P and P-Series power meters via a precision Type-N connector.

The sensor employs a dual-measurement architecture: a fast path for time-gated peak and peak-to-average ratio (PAR) analysis, and a stable path for low-level average power detection. This design accommodates both burst and continuous signal measurement requirements across diverse RF environments.
