Great. That makes it easier to use the standard PWM servo outputs as found on an Arduino development board for the requested capability. The tester I have been working on uses an Arduino Uno for both PWM signal generation and monitoring, along with a few other functions. But I needed to do a lot of extra work to build an interface board for it. If there is no need to have the power pin disconnected, it opens up the possibility of using a development version of the board (with and LCD shield) for the tester. This reduces the amount of custom wiring needed to get to a useful configuration. You would still need to wire a power switch, a few buttons, and one or two potentiometers, but I think it would be a relatively easy tester for most teams to build. As I said, I have a prototype version working, and I will try to provide more information and code after I test it and clean it up a bit more.
