Abstract: In the study,frequently met is the problem of connection between the computer and the digital devices based on GPIB which are used to complete waveforms and data sample.In this article an example of the connection between the computer and three oscilloscopes TDS 210 is given to introduce the method of set-ting up the GPIB address and using GPIB interface to accomplish the waveforms and data sample on Lab-VIEW,It is shown that this method is successful.
