发明名称 Method for analyzing a circuit board waveform for faults
摘要 A new method for analyzing an electrical waveform of the type portrayed on a graph includes the steps of selecting a waveform to be analyzed, establishing the boundary of a window-like area and generating a signal if the waveform is in a predetermined position with respect to the area. For example, a signal such as a failure signal is generated if the waveform is to be out of the area but, in fact, is in the area. The method also includes features for determining certain parameters, e.g., rise time, period and the like, for the waveform. The steps include selecting first and second points on the waveform and determining the time lapsed between points. Details regarding the structure of a new waveform analyzer are also disclosed.
