Research of ESD Generator Verification SystemZHENG Hui-zhi, WU Zhan-cheng, ZHANG Zi-kun Institute of Electrostatic ＆ Electromagnetic Protection, Ordnance Engineering College, Shijiazhuang 050003, ChinaAbstract: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.[著者文摘]
