Hi Techiess,
those values DON'T reflect any pulse width value - they are just arbitrary values used for setting properties of the DAQmx channel!
In a sub-vi of your "pulse width.vi" you find a property node where this ring is connected to. Switch on the context help and you will get some explanations for this property...
Those values are defined somewhere and the DAQmx driver expects them to switch between rising or falling edge detection.
Best regards,
GerdW
