[Elecraft] [P3] Reference level; scale

[Al Lorona]

The thing that will take most getting used to will be that the P3 calls the 
*bottom* of the scale the "reference level". On a typical spectrum analyzer the 
reference level is usually the *topmost* line.

Additionally, a spectrum analyzer thinks in terms of reference level and a scale 
(in dB per division), whereas the P3's "scale" is the total vertical distance of 
its display, from top to bottom. In my mind, I'm going to be dividing this 
"scale" by the number of divisions so that I can have an idea of the dB/div.

But these are artifacts of years of using HP and Agilent equipment. Time to 
learn a new system, I guess. :^)
