I suspect that the "typical phase noise of 0.035 degrees" spec is going to
make using it as a phase detector a bit of a challenge. You would have to do
some digging to see if it really does anything that a cheap double balanced
mixer does not do.

This might be off topic, and if so, pls disregard. (I am new to your
group..just listening lately, a little rusty on some of your talents.)
I have an older EG&G Model 5202 Quadrature lock-in amplifier around for
years waiting for a project. (.2 - 50Mhz)
It seems its' phase sensitivity could be used to discipline an oscillator to
a high degree of accuracy using its' DC-output.
Maybe it's not what it was designed for .I'm trying to find a use for it.
