Digital three-dimensional oscilloscope is a kind of digital storage oscilloscope, which not only can capture and display time-amplitude information of the signal, but also can reflect the probability of different events by different levels of brightness or color grading. The prominent feature of digital three-dimensional oscilloscope is that it has a higher waveform capture rate and its core is three-dimensional waveform mapping technique. First of all, the relationship between acquisition process and dead time is described. Random process theory is used to analyze how oscilloscope captures sporadic transient signal. A parallel processing architecture principle is introduced, which adopts three-dimensional waveform mapping technology. And then the mathematical model is described in detail. Then, the waveform mapping function of digital three-dimensional oscilloscope is designed and realized. Finally, test results indicate that the technology of waveform mapping increases the waveform capture rate and enhances the measurement performance.
