MFJ Antennae analysers? VNWA?

These questions are raised by the possibility of resurrecting a project
with
a former colleague from uni 43 years ago, now that we are both retired,
although it will be dismissed cynically as vapourware by some nasty
individual,
to produce a speccy covering up to 10GHz together with tracking genny
but based aroind COTS components that feature more and more
in domestic white goods.
There are two aspects of vector analysis under consideratiom; the first,
as for antennae measurement is to assess the amplitude and phase of
reflected
power from various circuits, which is where the interest in the VNWA arises,
but the second is the analysis of complex modulation, particularly
where there are constellations.
I can not think of any antenna that modulates signals.
