Hello,
Using the Ramp Pattern.vi, this is very easy to accomplish. All I did was modify the Gen Mult Volt Updates-Int Clk.vi to use the ramp VI. Then I set the ramp to start at 0 and end at 5 with 256 steps. From there, you just specify the AO Sample clock to run at 1 sample per second and to output 256 samples. See the attached VI. Let me know if you have any further questions.
Regards,
Sean C.
