DUt

DUT is an acronym that can refer to several different concepts depending on the context. In engineering and testing, DUT stands for device under test, the item being evaluated.

In electronics, embedded systems, and software testing, the DUT is the object subjected to stimuli and measurements. Test equipment applies signals to the DUT, and results such as voltages, timings, or outputs are recorded to assess functionality, performance, reliability, and compliance with specifications. Test engineers design test cases, fixtures, and harnesses to isolate the DUT from external influences, and documentation captures pass/fail criteria and observed anomalies.

Dalian University of Technology, abbreviated DUT, is a public research university located in Dalian, Liaoning Province, China. It emphasizes engineering and technology programs and conducts research across science, engineering, and management disciplines, with partnerships in industry and international exchange.

Other institutions and organizations also use the acronym DUT. Because DUT has multiple meanings, its intended reference is usually clear from surrounding context.
