Agilent/Keysight U2061XA

The Agilent/Keysight U2061XA is a USB-powered average power sensor delivering precise power measurements across RF and microwave frequencies from 10 MHz to 18 GHz. Direct USB 2.0 connection to a host PC enables immediate data acquisition and analysis without external power supplies. Measurement range spans -60 dBm to +20 dBm with ±0.5 dB typical accuracy, making it suitable for component characterization, wireless infrastructure monitoring, and radar system verification.

The sensor accepts multiple trigger modes - internal, external, or bus-based - and supports measurement functions including average power, peak power, and crest factor across modulated signal types such as GSM, WCDMA, LTE, Wi-Fi, and Bluetooth.
