Title:
WAVEFORM DISPLAY DEVICE AND ITS WAVEFORM DISPLAY METHOD
Document Type and Number:
Japanese Patent JP3934224
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the signal waveform display method of a waveform display device capable of observing the signal waveforms related to the latest measurement and those related to the former measurement simultaneously on a display part.
SOLUTION: The waveform display method of a waveform display device is structured so that the signal waveforms of those signals to be displayed are displayed on a display part based on the waveform data stored in a data storage means while the wavefom data on the signals to be displayed which is generated by a sampling in a time period for unit measurement ranging from the time of input of a measurement start signal to the time of input of a measurement end signal or by a specified time collapsed is stored in the data storing means. The waveform data generated by a plurality of consecutive unit measurements is stored in the data storing means by a ring system and, based on the waveform data stored in the data storing means, the signal wavefoms W1, W2, and W3 of those signals to be displayed related to a plurality of consecutive unit measurements are displayed in time series on the display part.
