【摘要】 本文首先分析了电磁场辐射原理,然后介绍了在一般条件下对电子线路板进行电磁辐射预实验的方法,最后将测试结果与标准实验室进行比较,从而证明对电子线路板进行预实验的有效性,为设计人员在设计初期及时解决问题提供了很好的参考。更多还原

【Abstract】 This paper analyse radiates principle of the electromagnetic field in the first, and related to the method of predict test to PCB’s electromagnetic radiation in the common condition. Then compared the result of the test with that of in the standard laboratory ,we can prove the validity of the method of prediction test to PCB’s electromagnetic radiation. It provides good consulting for electronic designers to solve problems on time in the initial designing stage.更多还原
