The Agilent/Keysight U2001A is a USB-connected RF power sensor that delivers direct measurements from 10 MHz to 6 GHz without requiring external power supplies or separate instrumentation. Operating across an 80 dB dynamic range with power levels from −60 dBm to +20 dBm, the U2001A integrates dual-range measurement paths optimized for both low and high power regimes. The sensor connects via USB 2.0 to a PC or laptop and is controlled through Keysight software platforms such as Power Panel and BenchVue, enabling real-time data acquisition and automated analysis.
