1MA178: The Y Factor Technique for Noise Figure Measurements
This application note describes in detail the steps required to
make a noise figure measurement on a spectrum analyzer using the “Y
Factor” technique. Background equations are presented for each step of
the calculation. In addition, guidelines are provided to ensure a
repeatable measurement. Measurement uncertainty is then reviewed,
including contributions due to the noise source, analyzer, and the DUT
itself. Finally, a software utility is presented that automates the
noise figure calculation using four measurements from a spectrum
analyzer. The utility checks the measurement guidelines and highlights
potential problem areas. It then calculates the noise figure for the DUT
along with the measurement uncertainty.

Kære Lars.
SvarSletY-Factor var titlen til din tale til Weekendavisens Litteraturpris i 2013.
Trods dette indlæg forstår vi ikke, hvad du mener med Y-Factor og hvorfor talen har fået denne overskrift?
Kan du forklare hvad intentionen/meningen er?
Hilsen de fortvivlede retorikere
