Figure 3-6. Noise Figure Measurement
The noise figure is calculated as follows:
NF = ENR – 10 log (Y – 1)
NF (dB):
ENR (dB): ENR of noise source
Noise figure
Y: Y = 10
N
1
(dBm): Spectrum analyzer indication value at SW OFF.
N
2
(dBm): Spectrum analyzer indication value at SW ON.
Remark
This measurement measures DSB. To measure SSB, add 3 dB to NF above.
