write to two ao lines

Is there a way to simultaneously output 2 waveforms on two different channels ( continuously) of the same card?

I have a PXI6723.  Can I output a 1 khz/3volt waveform on a0 and a1 at the same time?  I tried 2 different vis and I get a task error.

Thanks,

Clint

Sorry.  On a1 I'd like to output a 3vdc signal  ..  Striaght DC no freq.  So an ac signal on a0 and a DC signal on a1.

Hi there,

Yes, you can output different signals simultaneously on different analog channels.  Did you do a forum search?  When I searched "multiple analog outputs", I got something like 160 hits.

Also, given your brief description of what you tried, the error you're receiving is -50103.  Search "50103" for why you're getting this error. 

So there's a lot of information on the forums already about your question.  Rather than reinvent the wheel, I'm going to ask you to first look at the information that is already out there.

You should also look at the examples that ship with LabVIEW.  Under "Help", go to "Example Finder...Hardware Input and Output...DAQmx...Analog Generation" for some code that will point you in the right direction.

Hope that helps!

I always search D Forums before I ask and there is almost always an answer.  This time I found it in a white paper.

Thanks for the help
