Delivering IEC 61000-4-2 current pulses through transmission lines at 100 and 330 ohm system impedances

Device testing using an IEC-compliant hand-held 150 pF/330 Omega discharge gun was compared to a 50 Omega IEC waveform pulser. Cur-rent waveforms were recorded and components tested with both pulsers. To understand effects of different pulse source impedances, the 50 Omega pulser was modified to operate at 100 and 330 Omega delivery impedances.
