L Wang · Research and Exploration in Laboratory · 2010
This paper introduced the design of virtual digital oscilloscope which is based on LabVIEW.It adopts the data acquisition card to get external data,and realizes the display and measurement and other functions through software programming.The virtual oscillograph consists of data acquisition,digital filtering,parameter measurement,frequency spectrum,power spectrum analysis and wave storage modules.It has many advantages,such as saving wave form and measuring result,costing lower and extending function when needed.The experiments showed that this virtual oscilloscope has reliable operation and good performance,correct result.
