This could expand the measurement and control functions and application areas of the virtual instrument. The core idea of the virtual instrument is “Software is the instrument”! It means using the powerful computer resources to reduce system cost and enhance the system functionality and flexibility with high limit of the technical software that has been achieved with the hardware. This article deals with the design of dual channel virtua oscilloscope.The instrument was developed based on graph language named LabVIEW,and it can perform various tasks such as acquiring data,displaying waveform ,storing data,measuring playback,printing data,and online transmission. The experimental results show that the instrument enjoys such advantages as steady performance,precise measurement,expanded functions and friendly interface .So people at various levels may use it. Oscilloscope is a kind of general instrument which has been used in scientific research and engineering design. To be compared with traditional oscilloscopes, this research design of the virtual oscilloscope mainly has the following advantages : 1) Functionality and performance indicators can be extended. 2) Operation panel is clear and simple for beginners to grasp. 3) It also has a strong network of communications capabilities. Furthermore it has many functions such as data acquisition, data presentation, data storage, data playback, transmiting data networks and so on .
