| 摘 要： | 针对高功率超宽谱短电磁脉冲(UWB-SP)电场标准装置的可溯源性和不确定度进行了研究,完成了UWB-SP电场标准的溯源和不确定度评定。分析了向脉冲参数标准、S参数标准、长度标准等参量标准溯源的可行性,实现了通过间接量的溯源得到标准装置的不间断溯源链。研究建立了标准装置的电场不确定度评估模型,针对脉冲源输出电压不确定度、脉冲传输不确定度、标准装置机械工艺及装配不确定度等不确定度分量进行了评定,并对各不确定度分量进行了合成,得到了标准电场的合成扩展不确定度为8.4%。

| Abstract: | The traceability and uncertainty of ultra-wideband short pulse(UWB-SP) electric-field standard device was researched in this paper. There is no UWB-SP E-field national primary standard, we got the traceability of E-field from pulse parameters, S parameters and dimension parameters national primary standard. The mathematic model of the E-field was established. We evaluated the uncertainty of the source output, the uncertainty of transmission and the uncertainty of structure dimensions, than we calculated the combined standard uncertainty. Finally, the expanded uncertainty of the E-field produced by the standard device was 8.4%. |
