摘要
Labview是当今最为流行的虚拟仪器开发平台,本文介绍了基于Lab2view的GPIB总线的虚拟仪器及其对软硬件的要求,结合锁相放大器的二次开发实例,系统描述了虚拟仪器开发的一般过程.与原有仪器相比,Labview下的GPIB总线虚拟仪器最突出的优点是不需要额外的数据采集卡就可以完成数据的实时采集,并将实验结果保存起来,便于数据的后续处理,极大地扩展了原有设备的功能.
Labview is the most popular terrace in now virtual instrument development. Introduced the GPIB virtual instrument based on Labview and it's soft-hardware requirement, join together the second development of the DSP lock-in amplifier, described the general process of virtual instrument development. Compare with the original instrument, the most outstanding advantage isn't to need additional data collection card and then can complete the data collection, combining to keep the experiment result, easy to data of follow-up handle, expanded biggest the function of original equipment.
