Just wanted to say i'm enjoying this discussion. Until recently i did not have any scope and have often been frustrated with what i can and can't do with my multimeter. Some of you might say i still don't have one, because this is what i got (DANIU DSO188 <https://www.banggood.com/DSO188-Pocket-Digital-Ultra-small-Oscilloscope-1M-Bandwidth-5M-Sample-Rate-Handheld-Oscilloscope-Kit-p-1315186.html>) :) I was buying something else and it was so cheap i just added it on. It is small, self-contained, and battery powered, and has already helped me out a few times even though i have absolutely no idea what i'm doing with a scope.
Will come back to this thread when i'm ready for something better.
