Title:
WAVEFORM DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP3702845
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a waveform display device by which a measured waveform can be synchronized with a reference waveform so as to be overlapped and displayed by adding a point to start its comparison with the reference waveform regarding measured waveform data, and by which the efficiency of the confirmation operation of data deviated from the reference waveform is enhanced.
SOLUTION: The waveform display device is provided with a function to decide whether the measured waveform is within a preset decision range. In the display device, the starting point of the comparison of the reference waveform indicating the decision region with the measured waveform is stored, a point of time when the measured waveform is deviated from the reference waveform is used as a starting point, the measured waveform is displayed, the starting point of the comparison is used as the mark, and the reference waveform is synchronized with the measured waveform so as to be displayed.
