I have carried out settings described in paragraph 5-17.
I have got slightly better waveform, (see attachment) but it hasn't affected rise time.
It hasn't affected dimmed trace at 50ns neither.
So I performed that test, what David suggested me.
I disconnected 19 kV connector.
The scope was turned off at least one hour before.
I was very careful. But not enough.
As I pulled apart connectors, I have dropped that end of cable, which has a naked pin.
As David wrote it earlier, it has a residual charge for sure!
It has produced a very nice blue lightning, with some thundering.
So it certainly had some kV in it.
And now, what happened?
I was worried about, what went south because of lightning.
Because I didn't seen it, where the lightning was striked.
But I was lucky.
Be very-very careful, if you doing this!!!
Well, so this test proved, my feeling about a good PLD was right.
And what shows the screen, without PLD?
I have got a much smaller and dimmer picture.
So PLD doing its job.
