Didier If you are going to use a PPS divider to divide the oscillator frequency down to 1Hz, you will need to measure the inherent jitter of the divider to ensure that it doesn't degrade the measurement resolution. It may be necessary to resynchronise the divided output using a fast D flipflop to reduce the inherent divider jitter to less than the 20ps resolution of the 5370.
