The measurements were made with an upgraded 5061A (Datum tube and
10811-60109).

I have used it to measure my GPS clock at 2.0E-12 at t=100s before, so it's
actually inside the 5071A limit there.  I don't know where its floor really
is but it appears to be much better than spec (as are most 5071As,
presumably).
