swept sine

[Keelen]

I recently purchased a NI PXI 6722 DAC module and I was wondering what would be the most efficient method in order to create a program that would do a sine frequency or amplitude sweep (min value,max value and the time to get there)? I am currently using LabView 8.2.

Any suggestions would be greatly appreciated.

For frequency sweep, take a look at this NI Developer Zone. If you get a popup about a missing Waveform Buffer Generation VI, you should be able to find it under C:\\Program Files\National Instruments\LabVIEW 8.2\Examples\DAQmx\_Utility

For amplitude sweep, you can use any sine generation example and change the amplitude of the generated sine wave periodically until you reach the pre-specified limit.

Hope this helps.
