摘　　要：对于使用适配器供电的电子、电气产品,电快速瞬变脉冲群抗扰度和射频场感应的传导骚扰抗扰度测试的标准没有对适配器输出端线缆的布置方式做出明确规定,主要介绍适配器输出线缆布置方式的变化对注入到受试设备的电磁干扰信号大小的影响,重点对适配器输出线缆的4种典型的捆扎/折叠方式进行了试验验证。For typical electrical and electronic products which are powered through an external power adapter,the setup of adapter output cable are not specified explicitly in related standards about immunity to electrical fast transient(EFT)and immunity to conducted disturbances induced by radio-frequency fields.The influence on electromagnetic disturbance level injected into EUT is mainly introduced for different routing manners of adapter output cable.The verification tests are carried out for four typical routing manners of adapter output cable.
