The Keysight U2031A is a USB power sensor cable engineered for accurate average power measurements across RF and microwave frequencies. It delivers true-average power measurement through a dual-sensor diode pair/attenuator/diode pair topology, with an 80 dB dynamic range and measurement speed up to 250 readings/second. The sensor operates calibration-free with internal zeroing capability, eliminating external reference sources. USB 2.0 plug-and-play connectivity transforms PCs, signal sources, spectrum analyzers, or network analyzers into integrated power meter systems.
