A method for evaluation of uncertainties of noise parameter measurement

Schmidt-Szałowski M., Wiatr W.

Journal of Telecommunications and Information Technology

2002

nr 1

34-38

The assessment of uncertainties of a two-port noise parameters measurement, presented in the paper, relies on modeling 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 agrees with those observed in experiments. This method may be implemented in automatic noise measurement systems for on-line uncertainty assessment and for optimization of the design of an experiment.
