--- Quote from: User Manual ---At slower sweep speed, the sample rate is reduced and a dedicated display algorithm is used to minimize the possibility of aliasing.
The displayed waveforms will be more susceptible to aliasing when this function is disabled.

But it's not doing anything visible (except perhaps changing gradation), while mathematical techniques for anti-aliasing have been around for awhile. I think it's a bug (or an unimplemented feature - which they 'forgot' to remove from the manual).
Or if someone could post just ONE 'before/after' example of it actually 'minimizing' aliasing, I would be happy :)

Notice the 100MHz and 200MHz bandwidth options at the bottom of the trial list.

Yes, this has been commented on quite a few times throughout this thread. Haven't you read all [000081] pages? ;D Seriously though, it's known Rigol has put plans in place to sell BW if they think it's worthwhile to do at some point.
And welcome, BTW! First time's always the hardest ;)

Ah. I noticed it was just posted to YouTube four days ago. When I did a search on the thread and forum nothing came up so I posted it.

That's EEVBlog member studio25's video - and the thread where the video is posted (and which is investigating hacking the Rigol) is here. But thanks for posting here - I know it's sometimes impossible to find stuff on EEVBlog - hell, I often can't find posts I made myself. ;D
