Data Communication Equipment Test System Research

With the development of modern communications equipment and changes of communication mode, how to get information rapid and effective has become a key factor in the decision of victory, most of information transmission is mainly dependent on data communications equipment. Various stages of development, production, storage and maintenance, data communications equipment should be tested, test function, efficiency, automation and accuracy of the system will directly determine the overall performance of equipment, therefore, the data communication equipment test system has become the focus of national research and development topics.Currently, the developed countries such as U.S. and NATO already have a maturity data communications test equipment or system, and has been repeatedly used actual combat. Data communications equipment in China are growing rapidly, but the testing methods are relatively backward, research of the data communication equipment test system is still have many gaps.Research objectives is how to design and implementation data communication equipment test system, describes the history, present situation, characteristics, problems and trends of the correlative equipment and systems in domestic and foreign , focuses on the testing technology in test information identify, virtual instruments, LXI bus, radio frequency hybrid network, fighting physical simulation generation and test data processing.According to the demand for data communication equipment testing, describes the system design and implementation by the advanced technology, make the system in function with test a variety of communications equipment in a variety of communication links in the system on data and voice transmission, network, identify, positioning, using area, compatibility, analysis, processing and evaluation capabilities; In performance with fast, efficient, stable, automation and intelligence capabilities. Finally, all the main function of the test system was prove correct by the method of verification platform.Data communication equipment test system can be easily applied to a variety of models of data communication equipment for testing and evaluation performance, can also be applied to other electronic equipment performance testing, this solves the problem on large scale, high cost, low efficiency, low precision of the test system, achieve an automatic, efficient, reliable and precise objectives.
