摘要
系统以Agilent3458A八位半数字万用表及160 B低热电势电子扫描开关通过USB/GPIB总线串联后与计算机相连,利用电子扫描开关的通道切换功能及.NET的VISA32接口类构建实现对多种设备的数据采集。根据数据采集结果,通过软件对数据进行详细的数据分析及统计。系统利用Agilent3458A与电子扫描开关的功能特点结合多通道自动数据采集系统进行自动采集的设计思想,达到高可靠性、高稳定性的数据自动采集目的,最后通过实际应用展示了测试结果。
The system connects with the computer by cascading the Agilent3458A eight semi-digital muhimeter and 160B Low EMF electronic scanning switch through USB/GPIB bus, using the channel switching function of electronic scanning switch and the VISA32 interface class construction of NET to realize the data acquisition to a variety of devices. According to the result of data acquisition, detailed data analysis and statistics are worked out by the software. The system uses the Agilent3458A and functions of electronic scanning switch, combining the design features of muhichannel automatic data acquisition system, to achieve high reliability and high stability of the automatic data acquisition. Finally, the testing results are presented through the practical application.
