摘要

EN 55032定义了辐射发射测试的开放区域试验场(OATS)。燕麦有两种替代方案，半消声室(SAC)或全消声室(FAR)。标准规定的辐射发射试验的SAC限值和FAR限值不同。本文采用比较噪声发射极(CNE)法对SAC限值和FAR限值的一致性进行了评价。所有的测试都在同一个腔室中进行。铁氧体改性应用于SAC，以便作为FAR执行测试。因此，可以影响测试结果的变量数量保持在最小水平。测量在30 MHz至1 GHz的频率范围内进行。CNE的测量有两种方式，即天线固定在1.55米，在1米到4米之间移动。之后，比较了余量水平，并分析了标准中SAC和FAR的限量水平的一致性。

Experimental Analysis of Radiated Emission Limits Regarding Test Facilities According to EN 55032

EN 55032 defines an open area test site (OATS) for radiated emission testing. There are two alternatives to OATS, which are semi anechoic chamber (SAC) or full anechoic room (FAR). SAC and FAR limit values for radiated emission test are different according to the standard. In this article, the consistency of the SAC and FAR limits are assessed by using comparison noise emitter (CNE). All tests are performed in the same chamber. Ferrite modification is applied to SAC in order to perform tests as a FAR. Thus, the number of variables which can affect the test results is kept at the minimum level. Measurements are performed in the frequency range of 30 MHz to 1 GHz. Measurements for CNE were made in two ways that are the antenna being constant at 1.55 meters and moving between 1 meter and 4 meters. Thereafter, margin levels were compared and the consistency of limit levels for SAC and FAR at the standard was analyzed.
