I used to measure PLL setting time with extrapolation, which is, measuring the time it needs to settle to 100KHz, then 10KHz, then calculate the time it needs to settle within 1KHz, 100Hz, with the assumption that the frequency error decays exponentially.
I am wondering, if it is really possibible to measure the setlling time accurately to the resolution of 1KHz or 100Hz, with a SSA for example?
