I'm not sure why so many people are against the autoset buttons found on most every digital scope these days.
I started in the late 60's /early 70's using simple scopes made with vacuum tubes, so I am certainly no beginner and know my way around the scopes settings, in other words, I know how to find a trace.
But the autoset in my opinion is just a time saver for me, when I switch from one signal to another that may be two very different signals.
It can make all the same decisions I can make regarding timebase, volts/div, offset, and trigger level, and much faster than me to get a stable image.
So I use it as a starting point, almost always. It's useful.
Perhaps a beginner should hook the autoset button to a high-voltage spark coil under their seat cushion, until they have learned the other settings.
But I'm an old timer, I don't have much life left in me, I can use all the seconds I have been given
