Sounds like the Rigol model(s).
When I used DSOs a couple decades ago they didn't have the band-limiting filter for whatever sample rate it was set at, and it was easy to get bit by aliasing. The kids thesedays don't know how good they have it. We had to walk unfiltered stairsteps to school and back. Upstairs both ways.

People who don't understand sampling sometimes quote DSOs as an example to 'demonstrate' that Shannon was wrong. All they actually do is demonstrate that they don't understand sampling.
Congratulations, a pointless incorrect piece of information just to promote your belief, you should be a politician...😛
We cannot have power bandwidth of Nyquist frequency, safety from aliasing and a ringing-free step response all at the same time. Now i feel rather pity for the engineers, who have to get 20KHz bandwidth with 44 KHz sampling rate.

Bandwidth vs Sample Rate
https://en.wikipedia.org/wiki/Nyquist–Shannon_sampling_theorem
Music is bandwidth limited so has no frequencies outside or greater than 20k, whereas a square-wave with a periodic frequency of say 1MHz could have frequencies into the high MHz's or even the low GHz's dependant on its knee frequency so would need a must faster scope to display a true representation of the wave.

A self-taught musician I know routinely produces rhythms that sound very much like an accidental spill of bowling balls rolling down some steps...
I am, of course, using the word "rhythms" rather loosely.
On reflection, I think this actually supports your case...there's not much music in bowling balls falling down steps!

Music is just the word we use to describe art made from organised sound. Doesn't mean you have to like the organised sound 😉
I think gpauk had a little but, I think you will agree, well deserved dig at these Steps: https://www.youtube.com/watch?v=YMY58D8-B00
From the capital "S", I figured gpauk was referring to some cultural thing (though, mercifully, I had never encountered Steps before).
But I couldn't resist tweaking that sideways into a discussion of the musical potential of staircases...music escalier, perhaps, instead of music concrète? 🙂

Yeah but did you watch at least part of the video?
I'm trying to right global wrongs here as it is simply not fair that some may have escaped this musical affront to humanity. ;-)

I did indeed, until my protective hind-brain reflexes kicked in, and I ran away, screaming in mindless horror at the awfulness I'd just witnessed. 😱
Hours later, I can't entirely put a finger on what makes Steps quite as awful as they are. Perhaps it's that they look and sound like a combination of the very worst elements of Bond (the string quartet), Abba, Olivia Newton John, the Bee Gees, and Celine Dion, all mixed together in an awful amalgam.
Thanks very much for administering vigilante justice. To me.
Perhaps there should be a thread somewhere where we can share links to the worst music we've ever encountered?

Give thanks that you are not of the age and geographic location to have had daughters who were into steps and had the CDs that they then insisted on listening to in the car!
I'm almost recovered from that. I think years of watching the Eurovision song contest steeled me for the ordeal.
