信息技术设备 - 抗扰度特性 - 测量的限制和方法

[中文适用范围]： 本 CISPR 出版物适用于 CISPR 22 中定义的信息技术设备 (ITE)。本出版物的目的是制定要求，提供足够水平的内在抗扰性，以便设备在其环境中按预期运行。该出版物定义了其范围内的设备与连续和瞬态传导和辐射骚扰（包括静电放电（ESD））相关的抗扰度测试要求。定义了 ITE 测量程序并指定了针对 0 Hz 至 400 GHz 频率范围内的 ITE 制定的限值。对于特殊的环境条件，可能需要特殊的缓解措施。出于测试和性能评估的考虑，一些测试是在定义的频段或选定的频率上指定的。满足这些频率要求的设备被视为满足 0 Hz 至 400 GHz 整个频率范围内电磁现象的要求。针对每个考虑的端口指定了测试要求。 [外文原描述]： CISPR 24:2010 applies to information technology equipment (ITE) as defined in CISPR 22. The object of this publication is to establish requirements that will provide an adequate level of intrinsic immunity so that the equipment will operate as intended in its environment. The publication defines the immunity test requirements for equipment within its scope in relation to continuous and transient conducted and radiated disturbances, including electrostatic discharges (ESD). Procedures are defined for the measurement of ITE and limits are specified which are developed for ITE within the frequency range from 0 Hz to 400 GHz. For exceptional environmental conditions, special mitigation measures may be required. Owing to testing and performance assessment considerations, some tests are specified in defined frequency bands or at selected frequencies. Equipment which fulfils the requirements at these frequencies is deemed to fulfil the requirements in the entire frequency range from 0 Hz to 400 GHz for electromagnetic phenomena. The test requirements are specified for each port considered. This second edition cancels and replaces the first edition published in 1997, and its Amendments 1(2001) and 2(2002). It is a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - dated references updated; - option of using a 4 % step size for continuous conducted immunity test deleted; - revision of Annex A for telephony equipment including methodology for measuring the demodulation from a speaker/hands free device; - inclusion of new annex related to DSL equipment. The contents of the corrigendum of June 2011 have been included in this copy.
