某网络机顶盒有一个HDMI接口、一个网口、若干USB端口，塑料外壳。进行辐射骚扰测试时，该机顶盒的网口传输模式测试超标，需要分析其辐射超标产生的原因，并给出相应的对策。辐射原始测试数据如下：

数据分析：

1、水平部分：250MHz、375MHz、500MHz、625MHz、750MHz、875MHz频点能量比较强，接近测试限制；

2、垂直方向：在30-110MHz有一个窄带接近测试限制。

辐射源头分析：

1、水平方向的超标频点都是网络时钟频率125MHz的倍频点；

2、低频超标部分首先怀疑是电源引起的，在电源上增加磁环，没有改善，但是把网线拔掉后，低频部分改善很多。

结论：把网线拔除后，水平和垂直的频点都能得到很大改善，所以断定不满足测试要求的频点都是由网口设计产生。

处理措施：

1、在TR+/TR- TX+/TX- 增加33PF滤波电容，对策后数据如下：

2、更改网络变压器，两种变压器内部电路对比如下：

原变压器

更改新变压器，两种变压器区别如下：

1)从原理图可以看出:

原变压器的CMC在前面TX:P1-3 RX:P6-8, P2 P7 为中心抽头,TRANSFORMERS 在后面TX:P16-14 RX:P11-9, P15 P10 为中心抽头;

新变压器:TRANSFORMERS 在前面面TX:P1-3 RX:P6-8, P2 P7为中心抽头,CMC 在后面P16-14 RX:P11-9, P15 P10 为中心抽头。

2)从电性评估:

原变压器的TX:P1-3 RX:P6-8 的DCR 参数为1.2 ohms MAX,TX:P16-14 RX:P11-9 的DCR 参数为0.8 ohms MAX;

新变压器的TX:P1-3 RX:P6-8 的DCR 参数为0.8 ohms MAX,TX:P16-14 RX:P11-9 的DCR 参数为1.2 ohms MAX。

3)从材料评估: 新变压器使用了更好的抗干扰材料.(EMI测试可以看出)

3、测试数据如下：

增加对策后网口性能评估，眼图测试如下：

增加对策后眼图测试OK，对产品性能影响不大。

思考与启示

网络端口RJ45作为现在最常用的端口之一，它的辐射超标问题，也是我们经常遇到的，因此掌握它的整改方法的同时一定要在设计之初在器件选型和layout时给予足够的重视，才能避免后续整改浪费大量人力物力！

【经验】以太网为什么要增加隔离变压器？

韬略科技将在本文探讨以太网为什么要增加隔离变压器。以太网设计中隔离变压器在满足功能（差分信号传输）前提下，不仅能对后端电路起到抗扰防护作用，还能抑制共模辐射噪声。因此隔离变压器是以太网口的标配设计。

【经验】电源适配器的辐射发射分析及解决方法

电源适配器是小型便携式电子设备及电子电器的供电电源变换设备，一般由外壳、变压器、电感、电容、控制IC、PCB板等元器件组成，它的工作原理由交流输入转换为直流输出；按连接方式可分为插墙式和桌面式。适配器本质上就是一个开关电源，因此EMC问题也越来越受到大家关注，接下来重点分析辐射干扰产生的原因和处理措施。
