Re: [Avid-L2] OT: Chop mode on Tek Scopes

If I remember rightly it was to do with the timebase, you switched between
chop and alt depending on how fast the trace was. I think chop was for
slower rates and then you went to alt when you could see gaps in the trace.
I suppose it had to do with the persistence of the image. And I'll stop now
before we get into some diversion about projector shutters and persistence
of vision and show myself up as a bit of an old fart.
