The Keysight U2352A is a 16-channel USB modular multifunction data acquisition device designed for precision analog signal logging, waveform generation, and digital control in laboratory and industrial environments. Operating at up to 250 kSa/s aggregate sampling rate across analog inputs, it delivers 12-bit resolution across four selectable voltage ranges (±10 V, ±5 V, ±1 V, ±0.2 V) with typical ENOB of 10.5 bits and THD ≤ -70 dBc. The unit integrates two 12-bit analog outputs (update rate to 100 kSa/s), eight configurable digital I/O channels (100 kSa/s scan rate), and two counter/timer channels supporting event counting, frequency measurement, period measurement, pulse width measurement, and pulse generation to 250 kSa/s. USB 2.0 Full-Speed connectivity enables direct computer integration with minimal power draw (< 5 W typical from 5 V DC, 500 mA bus supply). BNC connectors interface analog channels; a 37-pin D-sub connector handles digital I/O and counter/timer signals.
