Agilent/Keysight U2056XA

The Keysight U2056XA is a USB-connected average power sensor for RF power measurement from 10 MHz to 54 GHz. It delivers real-time readings at up to 50,000 measurements per second with zero dead time, ensuring no pulse data loss during transient signal analysis. The sensor spans -70 dBm to +20 dBm across 10 MHz to 50 GHz, and -70 dBm to +15 dBm above 50 GHz to 54 GHz, accommodating both low-level and high-level signals without compromise.

Internal zeroing and automatic calibration streamline setup and reduce measurement uncertainty. Time-selective average power functionality provides full dynamic range across varying signal conditions, making the U2056XA suitable for wireless communications, radar systems, and satellite equipment testing. The 1.85 mm male connector accepts standard RF cables.

Keysight BenchVue software integration enables instrument control and data logging without custom programming, while built-in presets cover common radar and wireless standards: DME, GSM, EDGE, WCDMA, WLAN, and LTE.
