摘　　要：根据IEC61000-4-2的要求,研制了2种不同结构形式的静电放电电流波形校准装置,对SchaffnerNSG438和KeyTek MZ-15/EC型静电放电枪的电流波形进行了校准测试.经在不同电压等级和电压极性下的多次测试发现:其中一种校准装置测得的静电放电电流波形与出厂结果相吻合,即该校准装置的设计是成功的.通过试验对比和定量分析发现,校准装置的分布参数对静电放电电流波形的上升沿有显著影响.对于静电放电电流波形校准装置,仅满足标准规定的电压驻波比指标是不够的,必须对分布参数的影响予以高度重视.Two electrostatic discharge （ESD） current sensing targets with different structures are developed in accordance with IEC 61000-4-2 specification. Current waveforms generated by Schaffner NSG438 and KeyTek MZ-15/EC ESD simulators are verified with the developed targets. It is shown that the waveform parameters achieved by one of the targets are consistent with the data provided by the manufacturer, which confirms the success of the design of this target. The ESD current results achieved through different targets are compared and analyzed. It is proved that the rise part of the current waveform is strongly affected by the distributed parameters of target. It is not sufficient to only meet the VSWR （ voltage standing wave ratio） specification for the ESD current sensing target.
