The application background of ATE test platform and the necessity in the test maintenance of the electronic equipment are discussed, and the function, the composition and the working principle of ATE test platform are also described. The composition of the test program set (TPS) and the development and the design on the ATE test platform are introduced. Taking the current output control equipment for example, TPS development and design are discussed. On the basis of analyzing the test requirement of the current output control equipment, the test unit adapter (TUA) and the test program (TP) in TPS development are designed. The application of TPS shows that ATE test platform can test the current output control equipment and diagnose the fault.
