Bill,
this would be a good question for time-nuts (CCd here).
I don't know what slope your particular oscillator has, but if it is
negative then years ago someone posted schematics on how to invert the slope and
how to offset the EFC voltage and change the range etc using an Opamp..
That should be in the archives. Otherwise such circuits are pretty readily
available in the application notes of TI, LT, National, etc etc.
bye,

I guess my idea of controlling a 10811 with the LTE-Lite is dead as its
EFC has a negative slope. Any ideas?
Regards,
Bill
On the 10811, that OCXO can typically be mechanically tuned to have a 1.5V
nominal EFC set voltage. The LTE-Lite can drive from 0V to 3.0V EFC, so
that should be more than required on a good (well aged and good thermal
stability) 10811. We have not tried driving a 10811 with it yet though, so can't
say for sure. One requirement is that the OCXO has a positive EFC slope.
Bye,

Said,
Patiently waiting for my 10 mhz unit. What are your ideas on using it to
control a 10811 instead of the built in 10 mhz osc? Will there be enough
control voltage for the 10811?
