In general, we do not need to change the source power, since the device works for linear material.

If it is for certain nonlinear applications and you have to chage the power, you can scale the amplitude: the mode source has the default value of the power, which can be obtained through sourcepower(f). Once you get it, you can find the scale required_power/sourcepower, and modify the mode amplitude with the square root of it.  You can verify the result after running a very short time.
