Earlier I took the 1khz reference signal as the source and went through all the windows.
Then I did the same with the Siglent SDS1104X-E, but of course I checked the 1khz reference again to see if there were any differences.
Here are the pictures.

I have replicated them on MSO5000, they are absolutely the same as HDO800. It seems that Rigol have no interest regarding FFT, no improvement after all these years.

i recommend you need to work more and have enough sleep to get better view/comparison... cheers.

Did it with 997.5Hz.
Additional with 10ms/div = 6.25MSa/s.

Siglent will follow with 998.97Hz.


voltsandjolts:
Is this the broken Rigol Flat Top or the fixed Flat Top?  ;D

Martin72:
Btw flat top...
Here a  siglent flat top pic with drastically reduced FFT-points.
I find the similarity with rigol's amazing.
