I experimented with the SING sync mode and can’t get it to work. If I attach the probe to the internal pulse generator I can get it to trigger and I get one new screen everytime I press the R/S button, so far so good. Now I detach the probe, press R/S for it to be ready to trigger on a new pulse and then attach the probe and it does not trigger. It just continues to update the screen like in NONE mode. Shouldn’t it trigg and freeze directly when I attach the probe now?
