A Current Measurement Procedure for the ESD Generators according to the EN 61000-4-2

This paper presents a measurement technique for the Electrostatic Discharge (ESD) generators, which are constructed according to the EN 61000-4-2. Using a measurement system according to the European Standard 61000-4-2, the current that a ESD generator produces is measured for different voltage levels. The waveform of the current is recorded using an oscilloscope at 2.5 GHz and the current values at 30 ns and 60 ns are calculated. Automating this procedure the ESD generator is checked if it is in the actual limits that the European Standard defines. This procedure is a useful tool to recognise whether an ESD generator needs calibration or not.
