Ok. I tried to understand how this circuit works. While I can see
how a small and precise frequency offset can be produced, I do not
see how a small phase offset with fixed frequency can be produced.
At least not at the 100fs resolution level they are claiming in
the manual. Would someone be so kind and explain the working
of the circuit?

What is a diophantine setup?
It is upon moral qualities that a society is ultimately founded. All
the prosperity and technological sophistication in the world is of no
use without that foundation.
