How is noise figure calculated?

We read the output noise density to be -90dBm/Hz. To get a stable and accurate reading of the noise density, the optimum ratio of RBW (resolution bandwidth) and VBW (video bandwidth) is RBW/VBW = 0.3. Thus we can calculate the NF to be: -90dBm/Hz + 174dBm/Hz – 80dB = 4.0dB.

Next, measure the signal, S, from the middle of the baseline noise vertically to the top of the peak of interest. My measurements are N = 66 and S = 367 (arbitrary units). Most workers calculate S/N just as the ratio of the signal to the noise, so S/N = 367/66 = 5.56 in this example.

The noise figure NF is defined as the noise factor in dB: where SNR i, dB and SNR o, dB are in decibels (dB). These formulae are only valid when the input termination is at standard noise temperature T 0 = 290 K, although in practice small differences in temperature do not significantly affect the values.

How to measure noise figure?

Y Factor method is another popular way to measure Noise Figure. To use the Y factor method, an ENR (Excess Noise Ratio) source is needed. It is the same thing as the noise source we mentioned earlier in the “Noise Figure Meter” section.
