Research And Verification Of Electromagnetic Environment Test System

The electromagnetic environment is defined as the sum of all electromagnetic environment in a given place, which is defined as the sum of the electromagnetic phenomena in a specific area in the International Electrical Commission (IEC50 (161)-1990.This article mainly from the basic function of the electromagnetic environment test, from its test significance, system components and testing process problems and solutions, etc..The purpose and significance of electromagnetic environment testing is:1, it can help users to set up a unit before the use of the expected frequency can achieve the desired effect, to prevent the blind caused unnecessary losses; 2, it can be used as an important basis for radio management department. This paper briefly introduces the components of the electromagnetic environment testing system, especially the testing method and the calculation and analysis. After induction problems encountered during testing, try a variety of solutions, through continued exploration, summed up the different test methods of electromagnetic environment test on different frequency bands, and the antenna, spectrum analyzer, low noise amplifier and other equipment replacement collocation respectively after test, summed up a few suggestions:1, microwave the accuracy of testing requirements, using the parabolic antenna with Bell antenna effect is good; 2, although the spectrum analyzer has basically reached full frequency test, but different spectrum still have their own characteristics, there are some advantages of test frequency; 3, the low noise amplifier and attenuation although not all tests are available, but still need to carry the protection test is the first test equipment.Through the summary and analysis of the test to achieve the optimal effect of the device collocation, I hope that the existing test theory can be added, in the work to achieve the ideal test results directly.
