Siglent SDG1032 as bad as rigol DG812?

On the SDG2042X using Pulse waveform instead of Square seems to behave better for this case.  Ran it multiple times and they always come out looking good.

So you have the same issue (wrong pulses) on the SDG2042X ?

I am currently trying to test something. I want to have channel 2 as a trigger, and the other channel to test. I found only "track" to work in this case, but you cant have different loads on those.  :palm:

( Yes it does not matter in my case, but there are likely some cases...)

Could you try something?
- Set up square wave.
- set high 3.3V
- set low 0V
- Invert the signal

Does it then go below 0V?

Yes, on the SDG2042X inverting the output seems to be always relative to 0V, not relative to the Offset voltage setting as specified in the user manual.  So the 3.3V/0V setting gives -3.3V/0V levels when inverted.  It doesn't seem to matter if you use High/Low levels or Amplitude/Offset settings.

Inverting signal means exactly that: inverting it. Meaning multiplying amplitude values with -1 in analog domain.
It is equivalent to scope invert function.
It does not perform digital logic NOT function.
AWG is not logic gate. It can go negative and positive values, by design.
It is a good thing.
