Abstract :
This paper presents results obtained from a recent measurement comparison exercise of complex scattering coefficients of a microwave step attenuator. The results obtained by the eight participating laboratories are summarised in terms of the between-laboratory reproducibility. Multivariate robust statistical techniques are used to summarise the complex-valued data.
