Using signal generator function, how do I dial the frequency lower than 1 while keeping the entire waveform, phase and wavelength?

Ok Dennis.  I think those videos are a great place to start.  Thanks for your help!  -J

Hi Dennis,

I tried to follow the tutorial online on how to create an analog output, and my speaker isn't moving at all.  Check out my block diagram.  Any suggestions?

Also, I tried to use the read function as you said, and I think that might work, however its only letting me define the minimum and maximum voltages in the DAQmx task settings.  Is there a way to prescribe the waveform in the task itself?

Thank you so much!

Don't create and kill the task on every iteration of the while loop.  Those functions should be outside the loop.

You are using Waveform, 1 sample.  So you are writing exactly 1 sample and then killing the task.   You should be writing multiple samples.

Hi RavensFan,

Thank you for your help.  That seemed to work nicely!

Do you know how to make a transposed waveform chart or the like so I can view my waveform history and realtime update on the same chart?

Thanks.  And congrats to the Ravens for making it to the super bowl!
