示波器使用的计算机模拟

Computer Simulation of the Usage of Oscilloscope

本文介绍了用计算机程序模拟示波器使用的方法。软件提供了正弦波、方波和锯齿波等三种可选择波形,具有聚焦、亮度、波形上下位移、波形左右位移、扫描频率和输入电压范围等模拟功能,在计算机屏幕的左端显示出示波器面板和波形,并在右端显示出功能菜单。使用者通过选择菜单就能完成所有功能的操作练习。

The usage of oscilloscope is simulated by computer program.Three optional wave forms,i.e. sine wave,square wave,and sawtooth wave can be offered by computer software.The functions of simulation include focusing,luminence,vertical displacement of wave form,horizontal displacement of waveform,scanning frequency,and range of input voltage.The Panel and the waveform of oscilloscope will be on the left of computer display,while the menu of functions will be on the right.By choosing the menu,all the functions can be practised by the users.
