So now you are saying these figures represent a typical surge waveform,
as opposed to the worst case waveform you said a long time ago.
Still missing - your source that indicates nanosecond rise times and
100MHz spectrum.
What does the "/" mean in that case, anyway? I never got to ask you that
before. Does it mean "divide 1.2 by 50"?
It is standard notation in the surge field. 1.2 us risetime and 50 us
duration
