摘要
现有电子产品越来越重视电磁兼容性设计。由于设计复杂,多数产品不能一次性通过电磁兼容测试,需要经优化设计后才能通过。针对北斗船载终端按GB/T10250-2007进行电磁兼容性测试时,在156MHz～165MHz频率范围内出现电磁辐射电平超标问题,本文通过对辐射信号产生机理进行分析,确定电磁辐射源和辐射传导路径,并根据不同辐射源采取相对应的整改措施,保证终端的电磁兼容性能。试验结果表明,采取的电磁整改措施很好解决了该终端电磁辐射电平超标问题。
More and more attention is focused on the electromagnetic compatibility design in electronic product design available. Due to the complexity of the design, most products cannot pass the electromagnetic compatibility tests at one time and need more optimization The electromagnetic compatibility tests of the Beidou carrier terminals are carried out according to GB/T10250- 2007, the electromagnetic radiation level exceeds the standard in the frequency range of 156MHz-165MHz. The generation mechanism of the radiation signals is analyzed to determine the electromagnetic radiation sources and radiation paths. The corresponding rectification plans are adopted according to different radiation sources to ensure the electromagnetic compatibility of the terminals The experimental results show that the electromagnetic rectification plans can solve the problem of excessive electromagnetic radiation level.
