[GreenKeys] Re: Noise levels

[Don Robert House]

0 dBm is 90 dBrn

0 dBrn is -90 dBm

Since noise is measured over designed circuitry the tests need to be 
made at a proper test level point (TLP).  Hence the term dBrnc0 
(deciBel reference noise corrected to Zero.   Pronounced "DeeBrinKo"
Someday I will have DBRNC0 on my license plates.

Tee hee,

Don
