It was built to support the Home-link products- and just about 6-mos old.  Is that a OK from JCI to publish a brief overview on haw EXPENSIVE it gets to do full parametric testing traceable to standards vs a "Gold Unit" test?

I am not so sure that I could give that OK. I think most people that develop this kind of equipment for something that has never been done before realize how much time and effort goes into something. Especially if it is a good product.

Thé golden standard is the meter...

It is derived from the circumvence of the earth at Paris:

The meter was designed to 1/10.000 of the distance  from the north-pole to the equator, they went to great lenghts to measure the exact length of this small factor.

The idea is that the earth belongs to us all, and by deriving the meter from the earth it cannot be claimed by a country, political party or religion (in the spirit of the french revolution at that time).

Sometime we gave up on this idea because the circumvence of the earth changes, and measuring it is quite an exercise.
