Seems debatable whether it's worth worrying about details like this when the EFC signal is just going to go straight into a 20K-100K resistor in the OCXO, isn't it? I just use a simple resistor network to drop the bipolar DC EFC control voltage from my 11729C to the level needed by the 10811A in my 8662A, and I have no problem making measurements at the 10811A's specified noise floor, at least from 100 Hz and beyond. I suppose 1/f and popcorn noise is still a concern, but surely that's dominated by the relatively-large resistance between the EFC control loop and the varactor.
