h1. Noise Figure
The Noise Figure has been measured with the FSV spectrum Analyzer.
The optical link output power is measured with an input termination (done with 50 Ohm termination instead of 75 Ohm as not available) at a temperature of 290 K.
Noise Factor :
F = No / kToBG (No : measured output power noise; k : Boltzman constant ; To : ambiant temperature close to 290 K ; B : measurement bandwidth ; G : RF Gain)
Noise Figure :
NF=10*log10(Ftot)
