Noise Figure Measurements

What is a noise figure measurement?
Introduction.
In wireless communication systems, the "noise figure (NF)" or the related "noise factor (F)" is a number used to specify the performance of a radio receiver.
The lower the value of noise figure, the better the performance.
What are the units for noise figure?
The noise factor and noise figure are related, with the former being a unitless ratio and the latter being the logarithm of the noise factor, expressed in units of decibels (dB).
What is the formula for the noise figure?
The noise figure depends on these parameters, the circuit topology, and the value of external components.
If you have all this information, noise figure can be calculated. = kT = –174 dBm/Hz, where k is Boltzman's constant and T = 300 Kelvin).
A noise-figure meter is an instrument for measuring the noise figure of an amplifier, mixer, or similar device.
An example instrument is the 1983-era Agilent 8970A. 8970A Noise Figure Meter is a Keysight product numbers that were formerly part of Agilent.

Using a noise figure meter is the most straightforward way to measure noise figure. In most cases it is also the most accurate. An engineer can measure the Autres questions
