that is most likelly a TXCO, what is in the user's manual about warm up 
time? if they have a special precise reference -- like for spectrum 
analyzer or frequency counter that would have at least one magnitude 
better stability and would have OXCO,a good OXCO like the Milliren 260 
series or the double oven oscillators   from Morion [St Petersburg, 
Russia] ones --if they are always heated and have good power supply-- 
could have 3  x 10^-10 stability
