Abstract
In view of the fact that equipments are deficient in engineering colleges′experimental teaching,the development of virtual instrument on virtual platform is introduced.With LabVIEW software and data acquisition card PCI-6024E,a virtual digital storage oscilloscope is designed and implemented.This oscilloscope provides the functionalities of waveform display,I/O,storage,print and digital display of measurement parameters.The actual application result shows that the accuracy and stability of the virtual oscilloscope meet the requirement.With more software enhancement,the virtual oscilloscope achieves multi-purpose and can be used as spectrum analyzer,multimeter,frequency meter and so on.
