Very nice, thanks! Now we know the exact values the instruments uses and plug these into our calculations.

Yes - whatever it's worth.

Maybe you want to consider my analysis presented in reply #3561 in the following thread:

https://www.eevblog.com/forum/testgear/siglent-sds2000x-plus-coming/msg4318822/#msg4318822

One might come to the conclusion that these factors are all very nice (and different, depending on the source), but rather meaningless in practice - with one major exception...

RBBVNL9:
All true, but I find them useful to reconstruct the RTB FFT method / settings ;-)

RBBVNL9:
In my last video, the Rohde & Schwarz RTB2004 was still holding secrets in terms of how its FFT analysis actually work. In this video, I go into greater detail unravelling them.

Thanks to various people that contributed to this thread with useful suggestions and ideas!

I spent the whole evening (and partly night) watching your videos, reading the thread and your comparison document, that's a huge work, so thank you @RBBVNL9.

Wondering if you plan to continue updating the document or releasing new videos? I also watched your other recent videos on Anritsu hardware (wow, that's high-end gear!), but I was wondering if you were dropping this comparison topic.

Again many thanks.
