I have successfully downloaded and executed the sample program shown here:

and see the pulse train generate in my oscilloscope. When measuring the value of a pulse high, the oscilloscope says 5V.
How do I change it to 3?
Looking at the DAQ Create Channel node I don't see any inputs for amplitude, only frequency and duty cycle.
Where is the amplitude of 5volts being set and how can I change it to 3V?
