Voltage Ramp Up and Down

[Penny001]

I am very new to labview and trying to generate a ramp signal (ramp up from -3v to +3v for 520 steps and +3v to -3 voltage for another 20 steps). I want this ramp to be in a loop. I have already generate the ramp up and down separately in labview. I just have no idea how to put together into a continuous ramp and adding the loop. Can anyone help? Any suggestion would be appreciated!

For putting the ramps together, you can use build array. Right click for "concatenate inputs". To run through the ramp, wire your array through a for loop, and wire individual voltage to the input you need it. Put a wait time for your time between voltage updates.

Sorry, can't open your VI to see what you have already done but all you need to do is concatenate the arrays together and autoindex them in a while loop. 

Edit: change to for loop...not while loop.
