Let's say I have a clock circuit where the lowest frequency is 1Ghz, but the I want to measure the jitter on a 2Ghz signal. This means that the main signal will have two cycles in the PSS simulation, and it seems to me that the noise will be folded into the spectrum up to half the fundamental, meaning 0.5Ghz. In the end, what I want is an accurate jitter measurement on the 2Ghz signal. Is it possible?
