| From a product’s development to its application, the Electromagnetic Compatibili-ty(EMC) test is always an effective way to have a good command of its EMC condition.In addition, the results of EMC tests give a sufficient support for the EMC rectificationand prediction. However, the problem can be divided into two sides with respect toEMC system test: on one hand, due to the limitation of equipment’s volume, the EMCtest cannot be conducted in the anechoic chamber, at the same time, the standard EMCtest cannot satisfy the requirement of real time too, so the EMC site test should beadopted instead; on the other hand, for the improvement of accuracy and efficiency intest, the automatic test is seriously needed. So the EMC automatic site test becomes aneffective way to solve the problems of the system test.Research on the automation in EMC site test is the target in this paper. Therequirements and characteristics of EMC site test are studied at first. Based on that, thetest equipment setup parameters are optimized. Then, on account of the former methodson environment elimination, the existing model of environment elimination is modifiedand a method is proposed, which means to solve the problem on the elimination ofbroad band signal in the environment. After that, the feasibility of the method is studiedand verified by actual examples. In addition, the technology and application in EMCautomatic test is analyzed. With the combination of automatic test technology andenvironment elimination techniques, the EMC automatic site test system is built.Besides, based on the theory of software development, the software is designed for theautomatic test system finally. |
