基于虚拟仪器技术的电子测量仪器平台开发

摘要

Using LabVIEW graphical development environment and data acquisition card,a kind of electronic measuring instruments platform was developed based on computer. The composition of the virtual instrument platform was described,and seven kinds of common equipments were designed including the signal source,oscilloscope,electronic counter,voltage meter,etc. The e-lectronic measuring instruments platform were tested on the actual circuit. The experiment results indicate that the platform can replace conventional electronic measuring instruments,which provides a low-cost solution for electronic engineers to design and develop electronic products.%利用LabVIEW图形化开发环境和数据采集卡,开发了基于计算机的电子测量仪器平台.介绍了虚拟仪器平台的组成,完成了信号源、示波器、电子计数器、电压表等7种常见仪器的设计,并且使用虚拟仪器平台对实际电路进行了测试.结果表明,该仪器平台可以替代实际电子测量仪器,为电子工程师的工程设计和产品研发提供了低成本的解决方案.
