Agilent / Keysight U2000A 10 MHz – 18 GHz USB Power Sensor

The Agilent/Keysight U2000A is a USB power sensor that delivers precise RF and microwave power measurements from 10 MHz to 18 GHz. Connected directly to a PC via USB 2.0, it eliminates the need for a separate benchtop power meter and streamlines test system integration. The sensor spans a dynamic range of -60 dBm to +20 dBm with dual measurement paths optimized for low and high power levels, achieving measurement uncertainty of ≤1.9% at room temperature.
