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.

VI技术在GPIB接口DSO测量系统中的应用

数字存储示波器(DSO)具有应用广泛、采样频率高、测量精度高等特点，是信号采集和处理中常用的测试仪器。在多路信号测量中，多路信号的同步比较、采集、存储和绘图等方面存在问题。为了解决这些问题，分析了三种具有GPIB接口的LeCroy dso的特点，并利用虚拟仪器(VI)技术构建了dso测量系统。重点讨论了测量系统的软件设计和用户界面设计。该系统已用于某位置伺服系统的测试，结果表明该软件设计理念合理，运行灵活。测量精度和可靠性均满足设计技术指标要求。
