LabVIEW在是在计算机上进行数据采集、数据分析处理。实现虚拟示波器的功能主要有从外界采样的模拟信号，转化为相应的数字信号，在计算机上实现波形的显示，并能够进行简单的波形处理，可以显示波形的最大值、最小值、平均值，并能够根据需要放大波形的倍数而放大。(LabVIEW is in the computer for data acquisition, data analysis and processing. The function of the virtual oscillograph mainly consists of analog signals sampled from the outside world, converted to corresponding digital signals, the display of the waveform on the computer, and a simple waveform processing, which can display the maximum value, minimum value and average value of the waveform, and can be magnified according to the multiplier of the need to amplify the waveform.)
