Hi Richard,

This quote above bears directly to one of my observations. You define
by negatives, and that is a shoddy technical discussion worthy of the
creationist argument.

Tell us what it IS instead. A simple complex number is all that is
asked, derived from actual measurement. I've done this numerous
times, and not simply for milliwatt signal generators and have
returned these readings to the client with certificates of
traceability to Primary Standards Labs.

Barring any explicit answer that yields this complex number; then that
answer is simply conjecture and illusion that is commonplace in this
discussion. Draping it with programs and formula doesn't give
substance to the shape of that dream.
