要約(英語): The paper concerns calibration of generators for simulation of the Human-Metal Electrostatic Discharge (ESD) according to the IEC 61000-4-2 standard. It is shown that analysis of the ESD pulse in the frequency domain can be an indication if omitting the frequency considerations in calibration of ESD guns is acceptable. The calibration setup consists of a target (current converter), attenuator, coaxial cable and a wideband, single shot oscilloscope. It is much easier to use only a low frequency model of such a measurement path setup than consider a high frequency model. If, however, a high frequency treatment is indispensable, then a frequency dependent transfer impedance of the measurement path and approximation of the oscilloscope frequency response with an infinite impulse response discrete time filter are adequate tools. Comparison of power spectral densities (PSD) of theoretical pulses, measured pulses as well as the measurement path noise gives a good criterion for specifying minimal bandwidth of a setup required for reliable calibration of a given ESD gun. This paper is a resume of previous papers of the authors, in which these issues were presented in details.
