USB NI-6225 pulse modulation

Solved!
Go to solution

I am trying to modulate the frequency and the amplitude of the pulse coming out of the one of the PFI lines of the board.  Is there a way to change the amplitude of the pulse?

Are you referring to changing the digital logic level of the PFI lines?

The only control you have of amplitude is with an analog output task.
