Device under test (DUT)

A Device Under Test (DUT) is any electronic or mechanical device that is being evaluated or tested to ensure it functions correctly, meets specifications, and performs reliably. It is the specific item currently undergoing testing in laboratories or manufacturing environments. The goal is to verify the device's performance, safety, and quality before it reaches consumers or is integrated into larger systems. The DUT can range from small components like chips to entire machines, and testing helps identify any issues or defects needing correction.
