John,
it might easily happen ;)
Even the HP 434A that was introduced 50 years ago appears to be still in
use by some power nuts:

How accurately do you NEED to measure power? Is this the start of a new
Group... Power Nuts?
The 432A / 478A / 8477A and a good DMM is waaay good enough for ANY real
engineering use.

======================
and... I forgot to mention the Rohde & Schwarz NRS that goes from DC to
15 GHz.
The maximum accuracy method (advanced substitution method - using a
standard cell) described in the manual is probably what you're looking
for.
Btw. mine has all three available heads for 50, 60 and 75 ohms. I've
been close to selling it until I discovered what a marvelous instrument
it is.

We all have our various highly accurate frequency and perhaps time
references. Is there a relatively simple and inexpensive method of
making an accurate RF power level reference? If so, then what do we
calibrate it with, not already having such an accurate reference?
One possibility that comes to mind is an HP 436A power meter. These
are abundant and usually have no sensor probes (which are expensive).
They also have a built in 50MHz, 0dBm reference. However, without more
fancy test equipment, I have no way to calibrate the reference, or
even verify that it is accurate.
