We discussed this area a week or three ago.
You don't need a digital scope to determine if there is a pulse. A digital
scope may help to see the pulse and figure out what it looks like.
With an analog scope, you can either look at the blinking light that tells
you it's triggering, or you can reduce the sweep speed until you can easily
see the (flat) line from the beam each time it triggers.
I can see a 10 microsecond pulse with my old Tek 465. It blinks and I
roughly remember what the picture looks like. If I want to know a detail, I
have to look at the right spot and wait for the next pulse.
These are my opinions. I hate spam.
