Automated Test Equipment

Automatic test equipment (ATE) is any automated device that is used to quickly test printed circuit boards, integrated circuits, or any other related electronic components or modules. Nowadays, ATE devices are essentially always controlled by computers although in the past, custom-designed controllers or even relay controls were used.An ATE system can be as simple as a digital multi-meter (DMM) whose operating mode and measurements are controlled and analyzed by a computer, or as complex as a system containing dozens of complex test instruments capable of automatically testing and diagnosing faults in complex electronic systems.
