I am using the Analog Discovery 2, and the latest version of WaveForms, 3.7.5, on Mac OS 10.13.3.
I find that triggering the Scope on Channel 1 or Channel 2 works fine, but trying to trigger on either Wavegen channel does not give me any triggers. The same is true when trying to trigger off a pattern. The interface seems quite intuitive, but I must be missing something because I cannot get the wave form generator and the scope to synchronize, unless I trigger normally on one of the scope channels. Is there some documentation on how to do this?
