[Abstract]:With the application of large capacity storage and 3D waveform mapping and display technology in time domain measurement, the ability of digital oscilloscope to capture and observe abnormal signals is greatly improved. However, in the application of the existing storage mapping technology, either the original waveform data is lost after 3D mapping, or the capture rate is low in deep storage. In the application of display technology, the display mode can not be adjusted according to the needs of users, and the display method is single. It is not good for the observation of abnormal signals. In order to solve the above storage mapping problem, this paper synthetically uses the technique of single acquisition and single amplitude mapping and piecewise storage centralized mapping waveform 3D imaging to realize the function of high capture rate and quantitative analysis of waveform under deep storage. In view of the above problems, the waveform brightness adjustment and correction technology is used to realize more visual and effective observation and analysis of the waveform image details. On the basis of the private enterprise cooperation project, this paper transforms the storage mapping and display technology such as segmented storage centralized mapping technology, waveform brightness adjustment and correction technology into practical engineering achievements. At the same time, the project achieves and exceeds the 500MHz analog bandwidth 4GSPS real-time sampling rate, single channel maximum storage depth 256Mpts and 200000 wfms/s waveform capture rate and so on. It lays the foundation for further improving the system performance and improving the system function. In this paper, according to the order described in the following order: 1, the existing two main waveform storage mapping three-dimensional imaging technology are analyzed and theoretical demonstration, three-dimensional waveform display method in-depth analysis and theoretical proof; The whole system scheme of digital 3D oscilloscope in this design is obtained. The waveform storage and mapping system is designed, including the design of large capacity memory. The function design of waveform segmented storage centralized mapping and waveform general storage 3D mapping design, 3D waveform display system design, including the realization of luminance adjustment technology, The realization of parallel mapping vector display and the implementation of 3D window extension. Finally, the debugging and optimization of each functional module of storage mapping and display technology are completed, and the next research plan and prospect are put forward.
