The Signal and Test Definition (STD) standard takes the test requirements of the measured object signal as a starting point and describe the test requirements in a signal manner, which can provide better program portability for the automatic test system. STD standard defines the signal definition and description model, but did not provide a specific method of implementation. In order to solve the storage problem of test signal parameter and test requirement from the technical level, this article analyzes STD standard, designs the signals according to the standard, give out the signal component design scheme of the automatic test system based on STD standard and describes the interaction of signal components with the process of signal excitation. The design of the AC_SIGNAL signal component is taken as an example to validate the design of the signal component. Experimental results show that the design is feasible and can be a reference for the automatic test system.
