摘要
手持导航产品中，电磁干扰对产品性能的影响巨大。该文重点描述PND产品中EMI定位和整改问题的一般分析方法和手段，即通过组合使用通用的电、磁场探头，GPS有源天线，电压探头进行近场扫描，准确定位PND中的干扰源和干扰路径，并举例说明这些方法的应用。
In handheld navigation products, electromagnetic interference increasing affects its performance. This paper describes general analytical methods and means of the EMI positioning and rectification in the PND products, namely through the combination use of a common electric,magnetic field probe, GPS active antenna, voltage probe near-field scanning, accurately position the interference source and path in PND, and gave examples of the application of these methods.
