Study Of Certain Models Of Electromagnetic Interference Measurement Methods

EMC is playing a crucial role in the domains of war industry, the request is more strict and didrnitude, special electromagnetic compatibility certificate must be afforded for type weapon, because the result of military affairs campaign is direct influenced by its electromagnetic compatibility. Therefore, the manufacturers all around the world make a great effort to develop excellent test mehod and constituting the whole bag of tricks to estimate the ecectromagnetic compatibility of weapon system.The dissertation describes the background of the subject and the application; expatiates the development of electromagnetic standard; illuminates the configuration and application of electromagnetic test ground; introduces the theory of TS9975 test system of ROHED&SCHWARZ company; mainly interprets the function and the design of electromagnetic interfere test for corporation type production; also the layout, maintrnance and examination analyse of electromagnetic compatibility laboraotry , so that they constitute the authentication center of electromagnetic compatibility. During the project developing, the EMI test uses the advanced EMI test system.Integrating corporation shield room and anechoic chamber environment in existence, we progress preparation measurement for our type product. Using special test software makes the system, enhances agility, dependability and testing precision, and overcomes the disadvantage of the artificial inefficient and unreliable system that based on the separated instruments and low test rate. The EMI test system belongs to great, precious system. It isn't used for a long time, for some impersonal reason. The project putted in practice makes use of the resource in existence to increase asset value. Proper alteration for anechoic chamber increases using rate of the anechoic chamber.In this subject, I took the responsibility of reasoning the project, analyzing the system performance, sdudying test method, mainly studying the test method of the EMI test system. After the method researching, system programming, testing and observing for more than a year, the project has passed expertise appraisal, achieved the demand and gained good performance expected before.
