I use mine for looking at Arduino pins. It's great to be able to put out pulses when you're debugging things.
I do the same, but I've rarely needed to check more than 2 channels at once. For digital signals it's usually "something" vs the clock. And if there's any jitter/timing issue, it's "normally"** a problem only if it messes things up in the digital domain, in which case a logic analyzer should help you see quickly that something is off.
** For most cases.
The problem is that those don't have a real time display of the signals. You have to press "record" and then go back and analyze.
(unless you have some software that I don't...)
I just got an Analog Discovery 2 and that does have real time display (16 digital channels, 2 analog). Maybe a 2-channel 'scope would be OK for me now.
.
Fair, but recording is normally a good thing when you are working with signals that change million times a second. Can't see myself debugging fast changing signals in realtime. I'd miss like half a million transitions just by blinking.
Also, thanks for reminding me that I wanted an Analog Discovery board at one point. Now I'll probably spend the rest of the night watching video reviews and trying *not* to start saving for one. Maybe if I start a diet of cheap instant noodles
AND I can get everyone a cheaper Christmas present this year there might be a chance I can get one for myself before the year ends?
