It's not real convenient to do that, because I'm driving the signals through the DB25 connector, not the BNC's.
Meanwhile, I made the code do a "test pattern", which draws a square across the full dynamic range of the DACs. Fiddling with the X/Y gain pots doesn't seem to change the behavior, but changing the X/Y position does - so that's a hint...
So far, I've been running it next to my computer, where I can change the code easily to do experiments. But I guess it's time to move it to the "lab bench", where I can look at stuff with the o-scope.
