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.
