摘要
文章介绍EMC电波暗室性能指标中与1～18GHz归一化场地衰减NSA、场地电压驻波比(SVSWR)和场均匀性(FU)三项指标相关的IEC/CISPR/A和IEC/SC77B委员会草案CISPR/A/342/CD、CISPR/A/531/CD和77B/429/CDV,这三项指标的校验和评估方法既适用于全电波暗室也适用于在接地平板上加铺适当数量吸波材料的半电波暗室。
This article gives a review of IEC/CISPR/A and IEC/SC77B Committee drafts, CISPR/A/342/CD, CISPR/A531/CD and 77B/429/CDV, three validation procedures for normalized site attenuation (NSA), site voltage standing wave ratio (SVSWR), fielduniformity (FU) of EMC anechoic chamber. These procedures can be applied in both fully anechoic room and Semi-anechoicChamber with suitable amount of absorbing material on the ground plane.
