I would think this is especially true for non-local frequencies,
such as one received over the air. I'll leave it to you FMT
guys to comment on the magnitude of

I guess it depends on signal to noise ratio. With reciprocal counters, you
only need one period
I was looking at the wrong plot when I mentioned the noise floor of my
5370B in frequency counter mode; blame my temporary mono-vision after
having had some eye surgery!
If you look at http://www.febo.com/time-freq/hardware/5370B/index.html
*properly*, you'll see that the actual noise floor is

While were at it, in the case mentioned above I'm a curious
about their FMT frequency standard -- if it's really accurate
to parts in 10^12, as they imply, over 10 minutes. I could
believe this if it were an Rb or Cs-based

In the current (September) issue of the Microwave Journal there is a
pretty comprehensive article Oscillator Phase Noise: Theory and
Prediction. It may viewed on the Microwave Journal Web site

But watch out for the mistakes in some of the equations - e.g. the right
hand side of eqn 2 is wrong, but eqn 3 is correct, and eqn 9 is wrong.
Don't know if there are any other mistakes, but it's a good article so
far -

Make sure not to get near any of the equipment. Free-running
oscillators are sensitive to vibration or shock. You've probably heard
the story of my best Sulzer oscillator making small phase or jumps
which I eventually
