DAQmx linear ramping AO voltage

[rprince2]

Hi, 

I am trying to create a linear AO voltage using the DAQmx functions to control xy galvo mirrors. How can I create a linear ramping voltage where I have control over slope and amplitude of the votage ramp? 

Thanks

I would use the Ramp Pattern function.  Then just write the values to the Analog Output.

Thanks for the reply! 

I have tried using this function and it does work, however, is there a way to control the amount of samples that it uses? I would like a smoother ramping function than it seems i can get with this.

It is a polymorphic VI.  You can choose to have it create the ramp based on the number of samples in the ramp or by a delta.
