【Abstract】 This paper presents that the data obtained from measurement system which requires quick sampling rate are sampled by the digital oscilloscope with GPIB interface at first because it has wide sampling frequency-range, high sensitivity, good interference rejection and so on. And at the same time, I/O function of VISA in LabVIEW acts on the digital oscilloscope and controls it to work and transfer the measured data from the oscilloscope to PC to further analyze.更多还原
