Abstract :
It is shown that the common method using two reference noise sources for the measurement of the effective noise temperature of a conventional receiver system can lead to serious errors. These errors arise from attenuation and mismatch effects of the components in the measuring system and the uncertainty to which these effects are known. It is suggested that measurements on (mismatched) low-noise receivers are particularly prone to error.
