Is the Rigol DS1054Z still the best buy for a cheap entry level oscilloscope?
JS:
Auto is ok when trying to capture a steady square-wave, not so much for odd pulses like transmision line reflection or odd one offs events or one in a bunch of other stuff things. In that cases the auto function might (will) not know what do you want to see and what you don't

Interestingly Philips did analogue scopes with auto.

Same as the venerable Tek CROs.

Yes, and I use a calculator these days to do math too. But I understand the concepts behind what the calculator is doing. Pressing the equal button on a calculator, or the Auto button on a scope, doesn't teach you anything. The example from JS about "not so much for odd pulses like transmision line reflection or odd one offs events or one in a bunch of other stuff" is a perfect example of what we're talking about.
I like to actually understand my R&D equipment. But hey, maybe that's just me. Maybe Auto is good enough for design work these days, and I'm just an old fuddy-dud. (Speaking of equal buttons, my calculators don't have them because I use nothing but HP RPN. Two strikes against this old fuddy-dud? :))

Not sure I have ever used the Auto button on my scope.

Yep, the only time I ever use it is with a new model that I've not seen before....like, I wonder how good this works ?
Blindly connecting a scope and pressing AutoSet is demonstrating plainly you have no idea of the signal you expect to see or have no idea how to operate a scope !

I don't think I've ever intentionally used an Auto button. And I hate it when I do accidentially hit the Auto button, because I then have to go back and set everything to what I actually needed. :rant: There's no "undo" button. And Auto's idea of what I want to see is almost always wrong.
