Thanks for the info. I am driving it with 38.4 MHz from an 8642A signal
generator, locked to it's 10 MHz OCXO, not perfect but it has aged pretty
well and it is within 0.1 Hz of 10 MHz. The Wenzel datasheet says nothing
about the phase noise when locked. I will adjust the input level to get the
best phase noise. Can you tell me how far off 100 MHz it is when unlocked?
I am trying to determine if mine is typical or partially broken.

Thanks again,
