| Abstract: | A multi-function electronic measuring instrument was researched based on virtual instruments in this paper,and it can complete the same measuring functions as these common instruments do,such as oscilloscope,filter,spectral analysis instrument and ananlyzer for bode plot.The test results indicated that the measuring instrument can correctly filte signal and exactly measure signal frequency spectrum,frequency-response characteristic and waveform.And the measuring instrument can run stabally and has strong reliability,high measuring accuracy,quick response and adjusted performance so as to meet the requirement of measuring signal.With the quick development of virtual instruments,the functions of the multi-function electronic measuring instrument will be improved and it will have a good application prospect. |
