@Martin72's flattop window function is still the broken (original) one, the repaired one (albeit on a DHO1000, hence a different sampling rate) is shown in the screenshot.

To me, looking at (original) Rigol FFT windows, it looks like Flattop and Rectangular windows look pretty much the same.

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

So -- is the assumption that the Rigol uses the full duration of the record, to get to the indicated small frequency step -- but reduces that dataset by undersampling (using only every n.th data point) or some similar scheme?

Argh, I have to check, not that I made a mistake.
Thank you!
