Siglent SDG6000X series 200-500 MHz AWG's
Detlev:
Then I'm probably not quite right with my approach of looking at the fundamental wave of the square-wave signal and its 3rd harmonic separately.
Do you also have decimal values of the simulation?
Unfortunately I don't have a way to simulate this

GNU Octave?
Detlev:
Your simulation matches my measurements perfectly. Thanks for the simulation. :-+
Then the SDG6022X calculates correctly.
I didn't know GNU Octave until now. Let's see if I can figure it out. I haven't been in this area yet.

I extended the measurement to the 11th harmonic and the values match your simulation almost perfectly :)
I lowered the carrier frequency to 1MHz because the setup is a little less noisy and you can see low values better. The screenshot is attached.
The SDG6022X shows its sunny side :)
It's great to see that the simulation goes so well with the measurement :)
Now it would be interesting to see comparative values to other AWGs.
I wish you a nice day

Almost too good to be true!
