The function of the Find Pulse Width is added to the Logic Cube (LAP-C Series) of Zeroplus Logic Analyzer. It can make a comparison find for the waveform width in the channel. For example, the period of some Clock Waveform is 4.2us (Both the Positive Period and the Negative Period are 2.1us), but the Clock Period Error may happen under certain condition. At that time, the function of the Find Pulse Width can be used to mark the error point, which can improve the efficiency of debugging for engineers.
