Hi For a lab reference, “clean” is a relative term. Most (as in every one I’ve ever seen) instruments expect a dirty signal on the reference input. They phase lock an internal oscillator to clean it up. Past some (unfortunately variable) offset, the reference signal has no impact on the

Hi Bill, I think it makes perfect sense. But I have no idea how the units' loop stability would be with the 10811. That kind of testing is on the plate. You would preferably set the OCXO to a nominal tuning voltage of 1.5V using the mechanical adjustment, then let the LTE Lite do the rest.
