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. 73's Richard Clark, KB7QHC |
