摘要
根据高等工科院校实验教学中实验设备紧张的现实,介绍虚拟平台下虚拟仪器的开发,并用LabVIEW软件结合PCI-6024E数据采集卡设计实现了一款虚拟数字存储示波器,该示波器具有波形显示、读写、存储、打印和测量参数数字显示功能。实际使用结果表明,示波器精度和稳定性都能满足使用要求。在此基础上增加软件设计,还可实现频谱分析仪,万用表,频率计等功能,实现仪器的一机多用。
In view of the fact that equipments are deficient in engineering colleges＇experimental teaching, the development of virtual instrument on virtual platform is introduced. With LabVIEW software and data acquisition card PCI - 6024E,a virtual digital storage oscilloscope is designed and implemented. This oscilloscope provides the functionalities of waveform display, I/O,storage,print and digital display of measurement parameters. The actual application result shows that the accuracy and stability of the virtual oscilloscope meet the requirement. With more software enhancement, the virtual oscilloscope achieves multi- purpose and can be used as spectrum analyzer,multimeter, frequency meter and so on.
