| Abstract: | Use LabVIEW image programming software and data collection card LabJackU12 to construct a virtual oscillograph, which is based on digital storage and comprised a computer. The virtual instrument consists of electronic signal, data collection module and computer programming software. Its palette includes control component and indicator, its frame image consists of control end, node, linkage and indicator end. The virtual instrument realizes running through dispersed Fourier conversion, cycle signal virtual value calculation, two same frequency signal phasic difference calculation and frequency measuration. |
