Thank you so much Ken. One last question, appreciate your patience.

So PSTB only uses the transfer function that corresponds to when the input and output are the same frequency (sideband 0). Is there a particular reason for this? Intuitively, it seems like the logical choice and I don't have anything against it, but I haven't found any literature that says why sideband 0 is used.

PSTB uses the zero sideband because you are interested in loop gain. Loop gain needs the input and output to be the same point at the same frequency.
