Abstract :
We report results of a recent international comparison of thermal noise-power measurements, performed under the auspices of CIPM/CCE. The noise temperatures of two solid-state sources with GPC-7 connectors were measured at 2, 4, and 12 GHz. All results agreed within the expanded uncertainties. The comparison was performed in accordance with the guidelines recently adopted by the CCE.
