具有可互换性的虚拟信号发生器

摘要

对IVI(Interchangeable Virtual Instrument)技术规范的结构、特点及在软件中的应用进行了研究.通过虚拟仪器技术利用LabWindows/CVI工具开发了一套基于IVI驱动的虚拟信号发生器,设计的虚拟信号发生器可以兼容测控通过任何接口介入以及不同品牌的信号发生器,相对于传统仪器具有即插即测、兼容性好、可互换性强等特点.%Traditional oscilloscope is unavailable in remote measurement and control also lacks of interchangeability. Some study was done on IVI (Interchangeable Virtual Instrument) technical structure and the applications on software. This virtual scope program that is based on IVI driver was designed by virtual instrument technology and LabWindows/CVI, which is a tool to develop virtual instrument. The software can implement functions of measurement, debugging, monitoring and so on. Compared with the traditional instrument, virtual instrument has great advantages on remote control and interchangeability.
