Design of automatic testing system with GPIB interface

The purpose of the system designing is creating an automatic testing system for a receiving component based on the idea of virtual instrument.The main designing method is Visual C object-oriented designing and GPIB bus technology.This paper introduces the peculiarity of GPIB bus at first,and then evaluates the hardware composing and function of the automatic testing system.After that,the paper also introduces the method and idea of the software designing in detail,including the ways for generating test reports.The system can monitor the test process in real-time,collect the test data,do the integrated analysis and disposal of the lab data,and generate the test report and so on.The automatic testing system based on the idea of virtual instrument can enhance the efficiency,precision and automation of the test.And it has flexible architecture and good expansibility.So it can be well used in industry.
