摘要
测试一直是静电与电磁防护研究的瓶颈.针对ESD辐射场测试问题,提出了能量有效带宽和动态范围有效带宽的概念,并根据IEC61000-4-2标准规定的ESD电流波形,采用数值方法估算了ESD辐射场的带宽以及上升时间对带宽的影响.在此基础上成功研制了带宽为3.5Hz^1GHz(±1.5dB),动态范围60dB,测试灵敏度可调的ESD辐射场测试系统,并实际测试了IEC61000-4-2标准规定的水平和垂直耦合电场.
Test and measurement has been a bottleneck in researching electrostatic and electromagnetic protection. Aiming at test and measurement of the radiated field by ESD, it is proposed to express the bandwidth of ESD radiated field by effective bandwidths according to energy and dynamic range,and the effective bandwidths of the radiated field by ESD and the effect on bandwidths from rising time have been estimated numerically according to the ESD current waveform stipulated in the IEC61000-4-2. In terms of these analyses, a test ＆ measurement system of the radiated field by ESD has been developed successfully. Its measurement bandwidth is 3.5Hz - 1GHz （within ±1.5db） ,the measurable dynamic range is more than 60dB, and the sensitivity is adjustable.And mere,the horizontal and vertical coupling E-field stipulated in the IEC61000-4-2 were measured by the test ＆ measurement system.
