I am running LabVIEW 2015, and am using a cDAQ 9178 and an NI 9263 AO module. I am trying to generate two voltage signals: two square pulses on two separate channels of the AO to trigger two different pieces of equipment in a precisely timed way.
The problem is, I am having some inconsistencies in the voltage I am telling LabVIEW to generate and what I am measuring on my oscilloscope. I am using two "Simulate Signal" blocks to generate a 2V pulse and a 3V pulse, but measured on the oscilloscope I am getting ~20 volts and ~30 volts, respectively. When I try changing the amplitude of the pulses, I very reliably measure voltages on the oscilloscope about 10x higher than what I am telling the DAQ to do.
The code I am using is attached, as well as screen shots. Hopefully I am just making a silly mistake. Any help is appreciated.
