Instead of using the external reference input, any thoughts on actually
disciplining the internal OCXO to bypass the problem?
The end result would be no different than using ext-ref.
Right now I think the best approach to "smear" the error out, is
to run ext-ref from a frequency which is well-known, but not
synchronous with the input signals, for instance from a synth like
the 3336 or a carefully mis-tuned GPSDO
Would work if integer cycles is covered over the measurement time such
that samples is taken spread over the 100 ns reference cycle.
The EFC pin on the OCXO in the 5370 is grounded in a way that makes it
quite hard to unground.
Kapton tape into the connector, a wire soldered to EFC on the 10811?
