摘要
建立的电磁兼容试验设备标准装置——静电放电发生器校准装置,具有-3dB信号带宽为1GHz,采样速率为5GSp/s,且对静电电压高达±8kV,电流高达±30A的放电电流波形具有频谱及脉冲波形保真度。该装置能对静电放电发生器及类似设备进行校准或校验(复杂脉冲波形复现与量值溯源)。其校准不确定度为4.6%(k=2)。该装置采用专用精密电流传感器(放电靶)将放电电流波形转换(采样)为低电平电压波形,经恰当衰减后直接进入1GHz带宽的数字存储示波器进行显示和测量,还可对测量结果和波形进行存储和彩色打印。
Recently, a calibration equipment for the electromagnetic compatibility （EMC）testing system-the electrostatic discharge generator calibration equipment has successfully established by the National Institute of Measurement and Testing Technology（NIMTT）. The -3dB signal bandwidth for the equipment is 1GHz. The sample acquisition rate is 5GSp/s. The electrostatic voltages that can be calibrated is high up to ±8kV. The current to be calibrated is ±30A. It is a research tool for the evaluation of impulse waveform on electrostatic discharge generator or correlative products. The uncertainty of calibration is 4.6%（k=2）. The discharge current waveforms of the equipment pass through the appropriate current transducer are converted to a low level voltage. The attenuated voltage is fed directly to digital memory oscilloscope which bandwidth is 1GHz for display and measurement. In additional, the measured results can be printed.
