手机电磁干扰测试系统研究与实现

Research and Realization of the System of Mobile Electromagnetic Interference Measurement

参照手机测试标准,全面分析了进行手机EMI测试系统设计时需要考虑的因素和应对策略,然后给出了一套自测试系统的设计方案,该方案在满足标准要求的基础上采用虚拟置换法对辐射杂散骚扰测试进行了优化设计,缩短了项测试时间,提高了系统性价比。

All elements and corresponding solutions are analyzed when designing the mobile EMI measuring system according to the measuring standard of mobile in this paper.Then,a proposal of self measuring mobile is provided,in which the virtual replacement method （VRM）is applied to optimize the measurement of radiate harsh.On the basis of meeting the demand of the standard,the method reduces the measuring time and enhances the performance of price rate for the system.
