They  have a VCXO in the loop. It probably does not have much over +/- 50 
Hz of  useful range.
Whilst that would seem reasonable, I seem to be  seeing stability issues 
once the offset exceeds +/- a few  parts in 10^9.
 
Of the three I've adjusted so far, it seems to me that  there's quite 
noticeable jitter on the output frequency until it approaches  to within a few 
parts in 10^10 or 10^11 of 10 MHz.
