[time-nuts] 5370B frequency counter capability

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 about 3.7x10e-10
in 1 second, roughly an order of magnitude worse than the time interval
noise floor.  I also noticed that I ran that test five years ago... I
should try it again with some of my current equipment.

Sorry about that...
