摘要
对比了IEC CISPR 25:2021(第五版)和IEC CISPR 25:2016(第四版)的主要变化,主要阐述了车载天线接收到的骚扰、零部件传导发射以及零部件辐射发射测试的技术差异,变化较大的是移动业务的限值部分。目前通信方面迅速发展,各种通信设备普遍使用,第五版根据移动业务的实际情况进行了相应的更改及增项处理。测试设备如天线、接收机、前置放大器等有了进一步的要求,软件模板增加了测试频段、更新了限值变化。可为相关研究人员及应用厂商提供参考。
This paper compares the main changes of IEC CISPR 25:2021(Fifth Edition)and IEC CISPR 25:2016(Fourth Edition),mainly expounding the technical differences of the disturbance,conducted emission of components and radiated emission test of components received by vehicle antennas.Test equipment such as antennas,receivers,preamplifiers,etc.,have further requirements,and software templates have added test bands and updated limit changes.It provides a reference for relevant researchers and application vendors.
