Novatech DDS transition to manual strangeness #37
Description
Original report (archived issue) by David Meyer (Bitbucket: dihm, GitHub: dihm).
We’ve been working on some triggering issues with our 409B-AC devices (packaged versions of the DDS9m) and I’ve observed inconsistent behavior when transitioning to manual. Depending on the trigger mode used (async vs. sync) the buffered outputs would blank between shots.
I was able to fix it by placing an “M 0” command in transition to manual. I ended up calling the guy at Novatech and he confirmed that the phase alignment commands “M a/n” do not replace the function of “M 0” when going from table mode to single tone mode, so the change made with the double clutch that removed “M 0” from both transitions seems to be the rub.
I propose changing the phase alignment commands in the transition functions back to “M 0” and making the default phase alignment keyword point to continuous.
