Hello Mizar,
There are many examples in LabVIEW that demonstrate how to program the PCI-6052E. If you open NI Example finder and look under Hardware Input & Output >> DAQmx >> Analog Generation >> Voltage, you will find an example called Cont Gen Voltage Wfm-Int Clk.vi. This VI demonstrates how to generate time varying signals in LabVIEW.
If you are just starting to program in LabVIEW with a data acquisition device you might want to look at this online knowledge base found
here.
I hope this help.
