Abstract :
The paper presents the results of a comparison program between PTB and CMS which was started to estimate the performance of an automatic broadband noise power measuring system to be used for precise calibrations of noise sources. Two aspects are discussed, the influences of ambient temperature, and the effective system noise temperature.<>
