Abstract :
Digital storage oscilloscope (DSO) is, with applied far going, high sampling frequency and measuring accuracy, a common testing instrument in signal acquisition and processing. While many DSOs are used together to measure multi-channels of signals, there exist some problems in synchronous comparing, acquisition, storage and plots of different signals. In order to solve these problems, the features of three LeCroy DSOs with GPIB interface were analyzed and a DSOs measurement system was constructed by Virtual instrument (VI) technology. Software design and user interface of the measurement system were discussed with emphasis. The system had been used in test of some position servo system, whose results indicated that the software took on rational design concept and flexible operation. Beside, measuring accuracy and reliability of the system satisfied the requirements of design technical specifications.
