Abstract :
The assessment of uncertainties of two-port noise parameter measurement relies on modelling of sources of errors and an investigation of propagation of the errors through a measurement system. This approach is based on a simplified additive error model and small-change sensitivity analysis. The evaluated uncertainties agree with those observed in experiments. This method may be implemented in automatic noise measurement systems for online uncertainty assessment and for optimization of the design of an experiment
