To do this accurately, it is necessary to understand how a number of variables affect the overall measurement uncertainty. For measurements with an analyzer that measures noise figure, the measurement system contributors typically include: the analyzer itself the noise source the characteristics of the device under test (DUT) These factors interact in a complex way, but the overall measurement uncertainty can be modeled. The purpose of our 'Noise Figure Uncertainty Calculator' is to provide the measurement uncertainty associated with a particular DUT based on its characteristics and the specifications of the measurement system. For the model to be accurate in the Y-factor measurement technique case, the DUT must have reasonable reverse isolation, so that mismatch on one port does not drastically affect the impedance seen at the other port. For a more complete analysis refer to the article "Calculate the Uncertainty of NF Measurements", written by Duncan Boyd, Microwaves & RF October 1999, pp.93-102.
