摘　　要：车载音响系统是整车电器系统的一个子系统,其电磁兼容性会直接影响整车EMC性能。阐述在车载音响系统EMC试验中,通过选择4种不同格式的视频文件播放进行对外辐射试验数据比较,选择其中电磁辐射值最小的播放模式,以便最大限度地减少整车电磁兼容试验的误差。Audio system is part of the vehicle electric system, and the electromagnetic compatibility of which would directly influence the vehicle EMC function, the article demonstrates the a vehicle audio system EMC testing, in which four different formats of video files are played to compare their external radiation data. The playing mode with lowest radiation is chosen to minimize the vehicle EMC testing error.
