Thanks alot

I think you need to figure this out for yourself. I gave you all necessary information.

If you can't, maybe programming and signal processing is not for you.

What "case"?

You are still not making any sense.

Your reference signal has 12 points, so your generated signal should also contain 12 points (not 13!), otherwise you are throwing away part of the data. If you change the frequency or samples/second, you are no longer matching the reference signal, but measuring some poorly matched number of cycles.

If you simply want to generate a signal that has a different phase at each iteration, change the express VI to again reset the signal with each call, but now simply wire a new phase based on a multiple of the iteration count. See how far you get.

Check out Polar to Complex in the Mathematics toolbox, it should do the same.
