Are you telling all the rest of us that may have inferior equipment
that we shouldn't even try to measure things?

No. In fact, playing with a scope and a pulse generator is quite
educational.

And we aren't all dumb enough not to understand what gives us
resolution.

Trying to measure the thickness of a single sheet of paper with a ruler
graduated in eighth's of an inch is analogous. About all you can say
with certainty is that the paper is much thinner than 1/8 inch.

My last post gave a nominal value for the reflection coefficient of coax
with a migrated center conductor like N1PR postulated. At 2 GHz, the
2-inch section will be about 0.4 wavelength. Will you get detectible
reflections? Yes.

Well not exactly, IF, one were to take a "Stack" of said paper, that was
exactly 1/8 of an Inch thick, then count the number of sheets, and
divide the 1/8 inch by the number of sheets, One could get a VERY close
approximation of the thickness of a single sheet...... Duh...
