I created a Mask, in such a way that if my signal leave the Mask. I will have a Message Error. It's work but I should each time modify the values of Culsters of the function 'Limit Specification" If I change the Signal

You Will find in the attached file the block diagram.

Do you want to do this comparison on the fly or post processing?  You are currently doing a post processing.

 

I'm not understanding exactly what you are looking for.  Are you just looking for when the value changes?

How are you measureing brightness?  A digital signal is On or Off.

 

Duty cycle you can measure simply enough.  There is a VI called Pulse Measurements.vi that will do that for you.
