MEASURAND : Excess noise ratio
NOISE SOURCE : TSA1
REFERENCE PLANE : R140
FREQUENCY : 12.4 GHz

The key comparison reference value xR is calculated as the unweighted mean of the participants results with exclusion of outliers. Its standard uncertainty uR is computed as given in page 112 of the Final Report.

xR = 15.696 dB, uR = 0.005 dB

The degree of equivalence of laboratory i with respect to the key comparison reference value is given by two terms both expressed in dB:
Di = (xi - xR) and its expanded uncertainty Ui (k = 2). The equations for the computation of Ui are given in page 112 of the Final Report.

The degree of equivalence between two laboratories i and j is given by two terms both expressed in dB:
Dij = (Di - Dj) and its expanded uncertainty Uij (k = 2) with Uij = 2(ui2 + uj2)1/2.

Note that the terms Di and Dij are computed with the opposite sign in the Final Report.
