Ted Sowirka posted:I have a different, and possibly more relevant question for you "scope wizards." What does the waveform look like when it reaches the MOTOR? Assuming that you're running a modern, can-motored loco; and further assuming that the electronic E-unit (or Legacy motor driver, or PS3 motor driver) does some "chopping" of it's own, you could end up with a waveform that's nasty, brutish, and short. Or possibly a motor that's starved for power.
Remembering that can motors run on DC, and that our power is rectified (filtered?) with the loco, it would hopefully get a fresh start as a DC-ish signal before being perforated by the e-unit or what have you.
I have a Williams e-unit and an ERR cruise commander unit apart on the bench, I will look at those for you within the next day or two. Don't have any Legacy I am willing to take apart, getting the shell back on is murder.....
