Research on Automatic Test System of Optoelectronic Equipment Based on PC Bus and GPIB Bus

General Interface Bus (GPIB) is a widely used way to build automatic test system at present. It integrates virtual instrument technology, computer technology and powerful test instruments together. It test speed, powerful function and scalability, so it has test work. The research of automatic test for photoelectric on PC bus and GPIB bus has been carried out as a part of the research project of “automatic test system for automatic detection and maintenance”. The purpose of this research is to develop an automatic testing system for photoelectric equipment based on PC bus, which can be used for automatic testing and maintenance process. The main goal is to develop an automatic test system, which can realize the test and diagnosis functions by using the information provided by the control unit (PC). In addition, it should also have the following characteristics: high-speed data transmission; Flexible configuration.
