Simultaneous Analog Output

[EricAtOSU]

We are trying to generate two sine waves of different frequencies.  We found a program that generates one wave but would like to modify it to generate two.  We are using a PCI DAQ 6024E with two Analog Outputs.  We're not very experienced with LabView and need some help.  We've tried copying and pasting the existing code into a sequence structure and can generate the two waveforms one at a time, but not simultaneously.  Our project will not work unless we can generate the waveforms simultaneously.  Can anyone give us some direction?  We've read over Learn 10 Functions in NI-DAQmx and looked at some example programs, but like I said we are very new to LabView.  Attached is the original program we have been trying to modify.  Any help is greatly appreciated!

First of all, I would definetely recommend using the DAQmx driver with your 6024E card rather than the Traditional DAQ driver. The 6024E is supported under both drivers, however, the DAQmx driver is much easier to use and configure (especially if you are new to this stuff).

Here are some good examples of performing multiple analog outputs simultaneously:
