Design of LabVIEW-based Virtual Oscilloscope

With the development of computer technology,traditional instruments have turned to computerized instruments. Virtual instrument technology is the product of the combination of computer system and instrument system nowadays. This paper applies LabVIEW virtual instrument platform to complete the design of the virtual oscilloscope. This design can input signals by multichannel,and has the functions of setting,real-time acquisition,processing,displaying and storage of a variety of control parameters,so as to realize the signal waveform superposition,channel selection,signal parameter measurement and so on.
