Design And Realization Of Virtual Digital Oscillograph Based On LabVIEW

Because of electronics technique and computer technique developing so fast and their application in electronic measurement and instrument realm , the new test theories,new test method,new test realm and new instrument structure appear continuously.The function of electronics measuring instrument has changed thoroughly.In advanced test and control system, we hope that the equipments can not only carry on a test alone, but they can correspond with each other, thus constitute the test system, even test network system and carry out the information share, through contrasting, synthesizing and auto analyzing numerously signal to get accurate judgment.This is the request that the electronics profession puts forward to the test equipment, the traditional test instrument is subjected to very big restriction in this aspect. Because of the above-mentioned reasons, and with the fast development of the electronics technique and computer technical and and the price descending continuously, the traditional electronics technique design conception has been changed, which make partial function originally finished by hardware can be carried out by the software now. For example, the instrument's front-panel and the digital filter. Hardware function finished by software.But not a few function almost can't be realized by hardware, for example the complicated signal analysis, data statistics, and 3D picture etc., can be carried out easily by computer.Under the market requirement and related technique support, test and control instrument —Virtual Instrument(VI)...
