阴道分泌物分析仪

一、行业类别：医疗器械

二、电磁兼容标准：YY9706.102

三、产品名称：阴道分泌物分析仪

四、EMC电磁兼容问题要点：

阴道分泌物分析仪在实施电磁兼容测试时，其产品的辐射发射的测试结果不符合标准要求。

五、电磁兼容评估与分析

   辐射发射主要是在50MHz-60MHz、157MHz的频点余量低，100MHz、150MHz、200MHz等50MHz的倍频超出CLASS A限值线6dB左右。

干扰主要来源于电源的交流线与直流线相互串扰、显示的干扰以及PCB板网口VCC3.3电源的干扰以天线的方式空间辐射。

综上所述，本次整改方案将重点从屏幕内部驱动、电源线路、航插接口等进行整改，确保产品满足电磁兼容相关要求。详细整改方案如下：

1、显示排线屏蔽处理

2、将VCC3.3流经网口供电的部分切断，使其网口部分无供电。
