In order to meet the need for the automation of data acquisition, increase the efficiency of the digital oscilloscope and give full play to its advantage, an automatic data acquisition system has been, therefore, established. Through the connection with the interface of GPIB and the manipulation of several oscilloscopes by a single personal computer ,the collection and process of the signals ,and hence the result of them can be saved in database .This system was developed on the basis of LabVIEW Language. The outcome of the experiment indicates that this system can rapidly exactly capture the targeted signals and analyze the data of previous experiments according to the needs, which, to a large extent, provide the staff with great convenience. The system based on this method is simple, economical and practical, which has a significant value in use.
