With the memory function of the computer, computer simulation technology has been widely applied in various fields. The system is mainly used for teaching and the visualized demonstration of the oscilloscope functions will facilitate the teachers teaching. The thesis describes the basic concepts of simulation technology. And with application examples in real life about simulation, it discusses the current development situation and prospects of simulation technology, as well as the purpose and significance of the research in the thesis. The oscilloscope simulation system which based on simulation technology in the thesis is in Visual C + + 6.0 Programming environments. Using MFC and Visual C + + which provide a high degree of visual application development tools, the system can achieve such functions: the drawing of oscilloscope‘s control panel, the loading of bitmap resources, the dynamic displaying of different waveform with single-track and double-track channel respectively, and the achievement of amplitude separation and the variation of time cycle of the wave of double-track. Finally, the thesis concludes for the research, and points out the lack of the system and the content for discussing further.
