The whole point of an FFT is to find those, so...  :-//

In the images posted so far the peaks were much more visible on one of the two 'scopes.

Finding peaks is important in FFTs so I thought I'd mention it, that's all.

I didn't expect the Spanish Inquisition.

Cmon,

I was polite and factual. And explained something.

And peaks are easily visible on both, and better on Siglent because you can better control the process.
And I gave a solution to Rigol to make it better..
My post was completely bona fide..

They started posting some fixes. Good. Hope for the best.

In the few days I have the rigol here I can say (from my point of view, of course) that the GUI is another level, especially when you compare it to "older" models like the MSO5000.
Directly, there is no contest, this point goes to the new HDO (or DHO, whatever).
And I like it more than siglent“s GUI, partly.
Hope I can do further playings in the later afternoon..
BTW, anyone got a clue why the flattop window looks so drastically different on the rigol ?

Fungus:
Pet peeve: Can we please say "UI" instead of "GUI"?  :)

On that FFT setting menu I don't see any mention of either of number of points or number of bins or bin width. It seems it "automagically" decides on those and they are very important as to how it will look.
But it does look weird...
