Agilent / Keysight U2002H 50 MHz – 24 GHz USB Power Sensor

The Keysight U2002H is a USB power sensor that delivers accurate RF power measurements from 50 MHz to 24 GHz without requiring a separate benchtop meter. It operates across a -50 dBm to +30 dBm dynamic range using dual low and high power paths, capturing up to 250 readings per second for real-time signal analysis. The sensor connects directly to a PC via USB 2.0, enabling immediate power display and control through BenchVue software or third-party programming environments. Internal zeroing eliminates external calibration overhead and reduces measurement time, while internal and external triggering—including burst envelope detection—support both continuous and pulsed signal characterization. Trace display functionality aids gate placement and trigger threshold optimization for envelope analysis applications.
