Test terminal machine with waveform detection function and waveform detection method

A test terminal machine with waveform detection function includes a first storage, a second storage, a processor and a waveform generating module. The processor receives a waveform output command indicating a waveform time data of each cycle of a desired waveform output and a corresponding waveform action data, and a specific waveform output command indicating a waveform capture time range. The processor stores the waveform time data and the waveform action data into the first storage, and generates an actual waveform output accordingly. The processor captures an actual waveform time data of the actual waveform output in the waveform capture time range, and stores it in the first storage, and captures an actual waveform action data of the actual waveform output, and stores it in the first storage or the second storage device. The waveform generating module forms a specific actual waveform output according to the actual waveform time data and the actual waveform action data.
