Not much about this scope on the Internet, so hope this helps people

Excellent demonstrations and teaching. I learned so much! Thank you!

Thanks, Sometimes I like to try and cover how I approach things, not just do the repair, although I worry how much time it adds.

Nice Scope.

thanks, I picked it up in a job lot. I used to have a fluke 100MHz analog 4ch scope, but I think this might be better. It is amazingly clear even at 120MHz.
If only I had space to keep some of the things like this.
