[time-nuts] FE-5680A adjustments

Dear time-nuts: 

I have several FEI FE-5680A rubidium oscillators running and am looking for 
any alignment information that might be available. 

I can successfully communicate with them via the serial port and can control 
the DDS to change output frequency.  However, there are several pots and 
many test points on these units.  Just wondering if an FE5680A guru would 
mind sharing some information? 

Also, is there any kind of EFC voltage control for the C-field (to use one 
as the oscillator in a GPSDO)? 

Thanks in advance for any help.
