Dither is only an issue when using a control loop. The difference is that
with dithering you eliminate the D/A portion which doubles the cost from $
15 to $ 30. I personally prefer the analog approach. The same design can
have both options. Part of the program.

Ahh. Not so simple, then. I still don't much like the notion of
dithering, but it may be the only alternative. Or, as has also been
suggested here, add a manual C-field adjustment (but that would not
change the fact that the RS-232 adjustments would still be ~ 7e-13 steps).
Best regards,
Charles
