Download file is the same but HDO1K/4K but firmware files are different, it's enough to browse the GEL file container to see that.

I said this for those users who expressed doubt that the previous firmware was not for HDO1K.
Probable you are calling firmware the FPGA app files.
We know whats inside the gel file - https://www.eevblog.com/forum/testgear/hacking-the-hdo1khdo4k-rigol-12-bit-scope/msg4572985/#msg4572985

FPGA bins are part of firmware set, I made this clarification beacuse reading "the firmware is the same for both lines" could be misleading.
skander36:
There is one firmware file that can be applied to both 4k and 1K models.
dreamcat4:
a program like binwalk (or other similar firmware unpacker tools) should let you see what is the outline structure of those firmware regions. to examine better the regions and layout

Today I didn't have much time, but I could play a bit with the FFT function.
I was a bit surprised how little you can adjust/select.
There are no FFT modes like the Siglent(Normal/Peak/Average).
Also you can't set a number of points, overall the FFT features are very meager on the Rigol.
I then had a 1khz sine wave fed in with the SDG2122X, 50 ohms, 775mVpp.
I noticed two things, next to the fundamental there seems to be a small disturbance that makes the peak look a bit grinded.
Then the next thing, the change from hanning to flattop.
You can't adjust anything, so take it as it is, just how the displayed looks, that is quite different from my siglent scope. :o
That the function is displayed in a window is first of all a fine thing.
But the shifting to hit the point where the representation on the screen changes, is a bit fiddly, there is then the selection in the menu at the siglent a bit more practical, but that's just my impression.
But there is again a point, I would also want to have with my siglent:
The vertical scaling is on the right side, which I find only logical, that the fundamental is to be located either rather left or in the middle.
You can read it better when it is on the right. :-+
But that is only a question of software (hello, siglent.. ;) ).
Edit: Damn, pics are shuffled..again.
