CWG versus Ring wave
Lightning
Figure: 1.0.2-1
The ring wave appears at the terminals of equipment (equipment ports) as a consequence of switching in
power and control lines, as well as a consequence of lightning. The single event type and the decaying
oscillatory waveform are the most significant parameters of this test.
