The Keysight U2043XA is a USB average power sensor delivering accurate RF and microwave power measurements across 10 MHz to 18 GHz with a dynamic range of -70 dBm to +26 dBm. This instrument captures 50,000 readings per second and measures average power and time-selective average power from any modulated signal without dead time—every continuous pulse is recorded. Internal zero and automatic calibration reduce measurement uncertainty. The Type-N male connector and USB 2.0 interface enable direct integration into test systems. BenchVue software (included with instruments shipped after June 2019) provides PC-based control, data logging, and measurement visualization without requiring custom programming.
