静电放电模拟器校验装置研究

Research of ESD Generator Verification System

静电放电模拟器校验装置,根据IEC 61000-4-2标准设计。其电流靶通过同轴电缆与示波器相连,电缆两端则与BNC头连接,负责将ESD电流转换成电压信号供示波器测量。示波器带有软盘驱动器,能将数据以EXCEL格式或位图形式存入软盘,供微机打印波形和校验报告。该装置能自动采集静电放电电流波形。通过对该系统的不确定度分析,证实系统完全符合要求。

According to IEC1000-4-2 electrostatic measurement standard, design an ESD generator verification system. Its current targets connect with oscillograph via coaxial-cable. The two ends of cable connect with BNC pin and transform ESD current into voltage signal. The oscillograph has disk driver and stores the data in disc by EXCEL form or bitmap form for printing wave and verification reports. The system could automatically display the ESD current wave. Though evaluating its uncertainty, the system is absolutely accordant with the standard.
