I am new to time-nuts, and have just successfully phase locked a Jupiter GPS 10kc signal to a 10 mhz vcxo. There is jitter in the 10kc Jupiter output, as expected. How can the characteristics of the 10 mhz vxco signal be measured or analysed? A 10 mhz signal from a tcxo shows a clean sync with the locked 10 mhz signal, however there is low frequency 'jitter' between the two signals. The 10 mhz signal gains and looses over about a 40 nsec range on a random 20 to 40 second cycle.
What is the root cause of this low frequency oscillation? Is it the result of the phase lock 'searching'? Or is it inherent in the 10mhz tcxo output?
