| Abstract: | A virtual signal oscilloscope based on Lab-VIEW is aeslgned in the paper. It includes collecting waveform through single and double channel and measuring the parameters of the input signal voltage, fre- quency, period and so on. Additionally, spectrum analysis can be carried out by the FFT window; the waveform can be measured on displays after simple operation and the fax of it can be printed. The simula- tion results illustrate that the basic functions of traditional oscilloscope can be realized by the virtual oscil- loscope successfully. It has certain practical applicability and manufacturability. |
