Yes they are 4-5 kHz off when free running. Locked they are right on frequency.
They don't spec the phase noise when locked. I hope it is decent. The phase noise when unlocked is pretty good. I can only measure the phase noise indirectly by driving my Perseus clock with this and comparing phase noise measurements when using the internal clock. I may wind up using the internal clock when measuring phase noise and this when measuring Allan Deviation. Thanks for the suggestions.
