I'm having an issue using a differential probe and trying to trigger on a minimum pulse width violation. I am setting the trigger to wait on either edge and then detect a pulse width outside of a specific range. Whenever I do this it seems to trigger no matter what the pulse width is. The only thing that does work is setting the trigger to wait on a specific level, high or low, and then it will detect a pulse width outside of that range, but only at that level. I would like it to detect either a high or low pulse outside of this range, but when i set it to trigger on a don't care condition it never triggers. Any help is appreciated.
