If you want to simulate a delay in the signal, you have to modify the signal. Your wait does nothing to change the t0 or append data to the front of the waveform. Not sure what exactly you want to do.
I really wante to make a late phase shifter for a pulse compressor. and for this I have to delay several time a pulse, these signals that I obtain, I must submit them to a treatment. the problem is that i don't know how to make a delay for this pulse.
You want to delay a physical output after an acquisition? Then you would do something similar to your code except add the function that writes the pulse. If you use the Delay function, you will use the error in/error out connections to enforce dataflow. To simulate it, add another Square Waveform function. The while loop in your code does nothing so you can eliminate that.
