标准摘要
[中文适用范围]： 当车辆电气/电子系统浸入广播电台和电视广播电台、雷达和通信站点、移动发射机、蜂窝电话等源产生的电磁场中时，可能会受到影响。混响方法用于评估电子设备的抗扰度。频率范围为 500 MHz 至 2.0 GHz，并可扩展至 200 MHz 至 10 GHz，具体取决于腔室尺寸和结构。该标准修订版中添加了基于当前已知环境威胁的 HIRF（高强度辐射场）测试级别的可选脉冲调制测试。本文件介绍了 Mode Stire（连续搅拌）混响测试方法，该方法多年来已成功用作设计和生产阶段开发工具。 SAE J1113-28 文件中介绍了模型调谐（步进调谐器）混响测试方法。本文件为组件设计和测试工程师提供了在设计阶段早期以及试验和生产阶段评估电子设备对辐射电磁场的抗扰度所需的测试程序和性能要求。在开发阶段早期确保电磁兼容性将最大限度地减少项目后期成本高昂的变更，并防止在整车级测试期间过度的组件级强化。混响测试方法具有双重功能。该方法的主要功能是提供与电波暗室和移动发射机站点中的车辆级辐射抗扰度测试相关的台架测试程序。该方法可用于评估同一器件的不同设计的相对性能。 [外文原描述]： Vehicle electrical/electronic systems may be affected when immersed in an electromagnetic field generated by sources such as radio and TV broadcast stations, radar and communication sites, mobile transmitters, cellular phones, etc. The reverberation method is used to evaluate the immunity of electronic devices in the frequency range of 500 MHz to 2.0 GHz, with possible extensions to 200 MHz and 10 GHz, depending upon chamber size and construction. Optional pulse modulation testing at HIRF (High Intensity Radiated Fields) test levels, based upon currently known environmental threats, has been added to this revision of the standard. This document addresses the Mode Stir (Continuous Stirring) Reverberation testing method which has been successfully utilized as a design and production stage development tool for many years. The Mode Tuned (Stepped Tuner) Reverberation testing method is covered in the SAE J1113-28 document.Cross Reference:
