Siglent SDG6000X series 200-500 MHz AWG's

<< < (84/104) > >>

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
Detlev

Almost too good to be true!
