Hi mark_gin
I would start by looking at the context help for the Simulate Signal. The top part deals with the signal you are trying to simulate. The bottom part deals with the timing or sampling information. It sounds like you want the sampling information to change. Lets say you are simulating a real world signal of 100 Hz. Two cycles lasts 20 milliseconds. We know that we must sample at at least 200 Hz to reconstruct the signal. So our samples per second (Hz) could be 1000 Hz. 20 samples at 1000 Hz lasts 20 milliseconds. So if we sample at 1000 Hz for 20 samples we will have 2 cycles of our 100 Hz signal.
I hope that helps.
