The wave forms of electric and magnetic fields radiated by short gap discharges are measured to analyze electrostatic discharge (ESD) events in the near-field zone with the monopole antennas, the loop antenna and the 5.5GHz bandwidth waveform digitizer. The antenna outputs are corrected by the measured characteristics of the antennas. The relations between the measured electric field and the discharge currents are discussed.
