The Keysight U2352A is a USB modular data acquisition device that delivers 16-bit precision analog measurements and digital control in a compact, portable form factor. Operating over USB 2.0 with USBTMC-USB488 compliance, it functions as a standalone unit or integrates into a U2781A chassis for synchronized multi-module systems. The device combines analog input, digital I/O, and counter channels into a single platform suitable for laboratory benches and field deployments.
