PWM Testing Equipment

[Jim Wilks]

One item of electrical testing we seem to be at a real disadvantage with is our ability to test PWM signals.

I've been there all too often blindly swapping PWM cables and motor controllers in order to get to the bottom of a problem that all too often is not electrical.

I've seen postings here on how to build your own Arduino based PWM generator, but building DIY test equipment is not the route I'd like to go.

What I'm really looking for is a test box that:

1) can accept any PWM signal and display what it is receiving
2) generate a PWM signal based on some "hand control" input

Does anyone have any idea if such a thing exists and if so, where to get it?
