Agilent/Keysight U2057XA

The Keysight U2057XA is a USB-connected average power sensor delivering high-speed, wide dynamic range measurements across 10 MHz to 67 GHz. Built for R&D, manufacturing, and field service environments, it combines real-time measurement capability - up to 50,000 readings/second - with zero dead time for continuous pulse characterization. The sensor maintains full dynamic range accuracy across modulated signals including GSM, EDGE, WCDMA, WLAN, LTE, and DME, eliminating the need for manual attenuation switching during measurements.
