Description
Product Overview
Keysight positions the U2021XA as an USB peak and average power sensors for RF and microwave power measurement. It is part of the U2000 and U2020 X-Series USB Power Sensors. Model-specific evidence confirms frequency range: 50 MHz to 18 GHz, peak/gated power range: −30 to +20 dBm, average mode power range: −45 to +20 dBm (upper frequency limit depends on model/option), video bandwidth: 30 MHz, and sampling rate: 80 MSa/s, supporting engineering work such as wireless device characterization and calibration and production testing. Exact options, interfaces, accessories, calibration scope, and regional availability depend on the ordered configuration and should be confirmed before purchase.
