摘要
以某型号军用便携式终端在GJB 151A-1997《军用设备和分系统电磁发射和敏感度要求》的RE101和RE102测试中暴露出的超标现象为例,针对不同结构方式下的超标,分别采取了嵌套式多级屏蔽和整体屏蔽的整改措施。整改后,产品的测试结果符合标准要求。
To take a certain type of military portable terminal as an example, the problems of exceeding the limits of RE101 and RE102 test items in GJB 151A-1997 are put forward. Aiming at the problems with different structures, the measures of nested multistage shielding and integrated shielding are taken. After rectification, the test results can meet the requirements.
