Hello,
What programing environment are you using? If you are using LabVIEW, go to the NI Example finder (Help >> Find Examples). Once the NI Example Finder opens, go to Hardware Input and Output >> DAQmx >> Analog Generation >> Voltage. You will find all of the analog output examples in this folder.
If you are using another programming environment, the examples are usually located in the following folder:
C:\Program Files\National Instruments\NI-DAQ\Examples (DAQmx ANSI C, VisualC, VB)
or
C:\Program Files\National Instruments\MeasurementStudioVS2003\DotNET\Examples\DAQmx ( for .NET)
Hope this helps,
LA
