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...
