Agilent/Keysight E9325A

The Agilent/Keysight E9325A is a peak and average power sensor engineered for precision power measurements across RF and microwave frequencies from 50 MHz to 18 GHz. This instrument delivers dual measurement modes—Normal Mode for peak, average, and time-gated analysis of modulated signals, and Average Only Mode optimized for low-level signal characterization. The sensor achieves measurement speeds up to 1000 corrected readings per second via GPIB in Fast mode, with settling times as low as 0.08 seconds in average-only configuration.
