摘　　要：随着电子产品的工作频率越来越高,1 GHz以上频率的无意噪声发射日益增加。对于希望进入北美地区部分国家市场的电子产品需要获得FCC认证才能进行销售,因此越来越多申请FCC认证的电子产品需要通过1 GHz以上辐射发射测试。相比较CCC和CE认证,FCC认证的1 GHz以上辐射发射测试,在测试频率范围和测试方法有较大不同。这意味着产品即使通过了CCC或CE认证测试,如果不了解FCC的测试方法和相关细节就直接申请FCC认证,都有可能无法通过测试,延误认证周期。从FCC认证标准要求、测试方法和案例等方面进行了解读和分析,以期为申请FCC认证的企业提供一定的指导。As electronic products operate at higher and higher frequencies,unintentional noise emissions at frequencies above 1 GHz is increasing.For electronic products wishing to enter the markets of some countries in North America,they need to obtain FCC certification before they can be sold,so more and more electronic products applying for FCC certification need to pass the radiated emission test above 1 GHz.Compared with the CCC and CE certification,radiated emissions above 1 GHz test of FCC certification has a greater difference in the test frequency range and test method.This means that even if the product passes the CCC or CE certification test,if it applies for FCC certification directly without understanding the test methods and related details of FCC,it may fail to pass the test and delay the certification cycle.The interpretation and analysis is carried out from the FCC certification standard requirements,test methods,cases and other aspects,so as to provide certain guidance for enterprices applying for FCC certification.
