【摘要】 从计量角度阐述电磁兼容辐射骚扰测试标准的可比对性和经济性,依照可比对性原则,分析CISPR22:2008关于1GHz频段以上辐射骚扰测试对于场地布置中存在的受试设备离地高度、地面所铺设的吸波材料的高度,以及辐射发射限值适用条件等一些有争议的问题,认为只要场地满足了S-VSWR的测试要求,则地面铺设的吸波材料的高度等并不需要做出统一规定;相比之下,更重要的是要确保接收天线的主瓣能够覆盖EUT,并且详细记录测试现场条件。更多还原

【Abstract】 There are some disputes in China on the height of EUT, the height of the absorber on the ground and on the limits for the EMI test above 1 GHz per CISPR 22:2008. From the point of metrology on EMI test (comparability and reasonable costs), a detail analysis for these disputes are provided on the test site setup for EMI test above 1 GHz. The key is to make sure the EUT is in the main lobe area of receiving antenna, and it is not necessary to setup compulsory requirements on the height of absorber on the ground and on the height of desk to hold desktop EUT.更多还原
