Abstract In the data acquisition system, parallel technology is used frequently to improve the waveform capture rate,and makes use of the three dimensions of signal: amplitude,time and the amplitude distribution in time and the waveforms acquired in short time will be mapped into a picture with wave intensity or color grade.In this process, the waveform intensity adjustment and correction technology ensures that waveform display intensity hardly changes with the number of waveforms captured,and shows as much as possible the details of the waveform captured.The waveform intensity mapping process is analyzed,on this basis,the mathematical model of the waveform intensity adjustment and correction technology is described.With engineering applications, its function is designed in the digital three-dimensional oscilloscope,the waveform intensity is not changed basically and the more details of the waveform is showed.
