The amount of software in a scope like this would be massive.

Peak to peak noise can greatly depend on the sample rate and waveform update rate. i.e. all thing being equal, a faster update rate scope will appear "noisier".
This is why RMS noise is used for comparison.

Hello,

a misunderstanding has occurred. My submission refers to a table of Rich@RohdeScopesUSA in which he relates the RMS noise to the height of the entire screen, as if the RMS noise were measuring the width of the visible noise.

Are we talking here as beta testers on one unfinished (far eastern provenance) product, or we talking over one serious, expensive, industrial quality instrument?

I was able to reproduce the bug:

My Keysight 3000 literally went up in flames and released the magic smoke on its launch day.
An Extech multimeter blew up in my hands.
Rigol scopes have had too many bugs to count.
The list could go on.
