DSOs are downright sluggish and boring, I have one for the single shot capture business even though my analogue storage scope has always done that well enough for my uses.
One can question what these cheaper DSOs are really capturing in AD land at certain bandwidths..
Noobies should consider getting a
WORKING analogue scope NOW, get familiar with all the knobs, and see INSTANTLY what's happening on the screen when you probe or hook something up.
If you do buy one, get it locally,
PICK IT UP YOURSELF,
and get it home like you would a newborn baby
(whether it's yours or suspect foul play )
