摘　　要：X86平板电脑是军用移动信息系统的重要组成部分,具有性能高、兼容性强等优点,电磁兼容性是设备的关键指标;为满足X86平板电脑在环境恶劣的野战条件下的使用需求,需要对其进行针对性的电磁兼容性设计;通过分析X86平板电脑电磁干扰源,提出电磁兼容设计方法,包括屏蔽、滤波和PCB板设计等,重点是显示屏蔽和通信滤波设计;经试验分析,采取以上措施的X86平板电脑的电磁兼容性设计,能够满足国军标相关电磁兼容性要求。The X86 Tablet PC that has the advantage of high performance and good compability is an important part of the mobile infor- mation system in military, and EMC has become a key indicator of the equipment. To meet the demand of users under field conditions, the X86 tablet PC need to be targeted on electromagnetic compability design. By analyzing the sources of electromagnetic interference of X86 tablet PC, the article targets to make a proposal on the electromagnetic compatibility solutions, including shield, smoothing, PCB design, etc. Fix the attention on shield of display window and smoothing design of the communication interface. Results of experiments show that the design of X86 tablet PC adopting the methods above is able to meet the requirement for GJB.
