The Keysight U2353A is a USB modular multifunction DAQ offering 16-bit resolution, 16 SE/8 DI analog input channels, 2 analog output channels, 24-bit programmable TTL I/O, and 2 general-purpose counter channels — suitable for data logging, design validation, and physical measurement across a broad range of industries.

Typically includes:
• AC/DC power adapter
• Power cord
• USB extension cable
• L-mount kit
• Quick start guide
• Product reference CD
• Keysight IO Library CD
• Certificate of Calibration
• BenchVue software licence (BV0025B)

The Keysight (formerly Agilent) U2353A is part of the U2300A Series USB Modular Multifunction Data Acquisition family — a high-performance, PC-based DAQ solution designed for design validation, manufacturing, research and development, and data logging across industrial and educational environments. The U2300A Series consists of two families: four basic multifunction DAQ models and three high-density models, all using high-speed USB 2.0 (USBTMC-USB488) for plug-and-play, hot-swappable connectivity.

The U2353A offers true multifunction capability in a compact, paperback-sized module. It can operate as a digital multimeter in polling mode, or as a simple oscilloscope in continuous mode with basic triggering. The burst mode feature simulates simultaneous analog input acquisition for maximum throughput. Analog outputs support predefined or arbitrary waveforms, making the module well suited to closed-loop feedback and stimulus applications. The 24-bit digital I/O channels enable control of switches, relays, and solenoids.

The device functions as a standalone unit or plugs into the U2781A modular instrument chassis, enabling synchronised multi-module measurements with support for up to 384 channels in a chassis configuration. Compatible terminal blocks (U2901A / U2902A) simplify signal connections.
