电磁兼容性（EMC）.第4-3部分:试验和测量技术.辐射、射频、电磁场抗扰度试验

[中文适用范围]： 本部分的IEC 61000适用于电气和电子设备对辐射电磁能量的抗扰度要求。它规定了测试电平和所需的测试程序。本文件的目的是建立评估电气和电子设备在受到辐射射频电磁场作用时的抗扰度的共同参考。IEC 61000本部分中记录的测试方法描述了一种评估设备或系统对不靠近待测设备的射频源产生的射频电磁场抗扰度的一致性方法。测试环境在第6章中进行了规定。注意1：如IEC指南107所述，这是IEC产品委员会使用的基本EMC出版物。正如指南107中所述，IEC产品委员会负责确定是否适用此抗扰度测试标准，如果适用，则负责确定适当的测试电平和性能标准。TC 77及其分委员会准备与产品委员会合作，评估特定抗扰度测试对其产品的价值。注意2：在IEC 61000-4-39中定义了针对靠近待测设备的射频源的抗扰度测试。本文件专门致力于保护免受数字无绳电话和其他射频发射设备的射频发射的影响。注意3：本部分定义了用于评估电磁辐射对有关设备影响的测试方法。电磁辐射的模拟和测量对于定量确定影响而言不够精确。本基本文件中定义的测试方法的主要目的是在各种测试设施中建立测试配置的良好可重复性和测试结果的重复性。本文件是一项独立的测试方法。不可能使用其他测试方法作为声称符合本文件的替代品。 [外文原描述]： IEC 61000-4-3:2020 is applicable to the immunity requirements of electrical and electronic equipment to radiated electromagnetic energy. It establishes test levels and the required test procedures. The object of this document is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to radiated, radio-frequency electromagnetic fields. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of an equipment or system against RF electromagnetic fields from RF sources not in close proximity to the EUT. The test environment is specified in Clause 6. NOTE 1 As described in IEC Guide 107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide 107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and if applied, they are responsible for determining the appropriate test levels and performance criteria. TC 77 and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products. NOTE 2 Immunity testing against RF sources in close proximity to the EUT is defined in IEC 61000-4-39. Particular considerations are devoted to the protection against radio-frequency emissions from digital radiotelephones and other RF emitting devices. NOTE 3 Test methods are defined in this part for evaluating the effect that electromagnetic radiation has on the equipment concerned. The simulation and measurement of electromagnetic radiation is not adequately exact for quantitative determination of effects. The test methods defined in this basic document have the primary objective of establishing an adequate reproducibility of testing configuration and repeatability of test results at various test facilities. This document is an independent test method. It is not possible to use other test methods as substitutes for claiming compliance with this document. This fourth edition cancels and replaces the third edition published in 2006, Amendment 1:2007 and Amendment 2:2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - testing using multiple test signals has been described; - additional information on EUT and cable layout has been added; - the upper frequency limitation has been removed to take account of new services; - the characterization of the field as well as the checking of power amplifier linearity of the immunity chain are specified.
