Abstract :
IVI Specification is a technology framework promoted by IVI foundation (a consortium of vendors, integrators, and users), whose purpose is to advance instrument interchangeability and enhance software interoperability. IVI defines two distinct driver architectures: IVI-C and IVI-COM. IVI-COM is an interface specification of instruments drivers for Common Object Model (COM) applications. It is independent of programming languages and widely used. But it also has defects, such as: complex architecture, difficult to develop and expand, limited development environments. LabWindows/CVPM is a popular ANSI-C programming environment owned by National Instruments Incorporate. It is easy to learn and simple to develop test programs and drivers. But C is not an object-oriented language, so it is difficult to create complicated IVI-COM components. This paper promotes a light-weight COM-Based instrument interchangeable framework; it removes the defects of IVI-COM and realizes distributed measurements. An implementing approach of the components in CVIis also discussed.
