“…The operating temperature of the termination is in the range 650-700 K, with output noise temperatures from about 600 to about 650 K. The PTB radiometers are of the switching (or Dicke) type. For the 2 and 4 GHz measurements a coaxial radiometer [1], [5] is used, and for 12 GHz an R-100 waveguide radiometer [6] is used.…”

We discuss an international comparison of thermal noise-power measurements (GTRF-92-2), which has recently been completed under the auspices of the Consultative Committee for Electricity and Magnetism (CCEM). The noise temperatures of two solid-state sources with GPC-7 connectors were measured at 2, 4, and 12 GHz at the national laboratories in France, Germany, the United Kingdom, and the United States. Good agreement was found among the results from the different laboratories, with all results agreeing within the expanded uncertainties, which ranged from approximately 0.5% to 2.9%. The comparison was performed in accordance with the guidelines recently adopted by the Bureau International des Poids et Mesures (BIPM).

“…The independent uniform distributions are therefore recommended for usage (in the case described above) by the guidelines of the Western European Calibration Cooperation (WECC) [24] and the Comit6 International des Poids et Mesures (CIPM) ( [20,21]; see also [1]). For several measurements with interval uncertainty, similar formulation leads to the conclusion that each error is uniformly distributed, and the corresponding distributions are statistically independent.…”
