Paul,
 
there is a large unit-to-unit performance variation on these type of  
products, you may have a very good 10811 OCXO in the HP unit, and a so-so OCXO  
in the Thunderbolt.
 
This is normal, see Tom's measurements of different Z3801 units against  
each other, some are way better than others..
 
Bye,
Said

Recently  I put a 2201 back into service with  a home brew down converter.
I am  a bit surprised that when I use it to measure the Tbolt and then the
HP  3801.
The 3801 comes out always better by a decade actually. Granted what I  am
seeing is way down below a e-12th and in fact what I am reading seems  nuts
to me.
But can a 3801 run that much better then the Tbolt?
I  kind of thought they would both be in the same  region.
Thanks
Regards
