Output continuous 5V and Stimulation signal at same time

[Emily_aeroeng]

Hello,

I am trying to output a constant 5V signal to power a test bench, and output a stimulation signal (create small magnetic field, etc) at the same time.  I am trying to use DAQassistant with multiple channels for output, but I can't attach one data set to AO0, and the other data set to AO1. Please advise; my code so far is attached.

Thank you!

Many DAQ cards provide a constant +5V output.  Which DAQ equipment are you using, and does it have such an output?  If so, use that instead.  It will handle higher current than an analog output.  The analog output lines are not designed to power anything, they are purely for signaling.

It does, and it never occurred to me to just check it; I thought it had to be commanded out. Thank you!!
