Noise Parameter Uncertainties from Monte Carlo Simulations
James P. Randa, Wojciech Wiatr
We present results for uncertainties in noise-parameter measurements, obtained using a Monte Carlo simulation of the measurements. Sets of data were generated to simulate measurements on a low-noise amplifier, with given uncertainties in the underlying measurements, including the standard noise temperature (hot or cold), the ambient temperature, the reflection coefficients of the terminations, the scattering parameters of the amplifier, the power measurements, and variations in the connections. Each set of simulated measurement results was analyzed to determine the uncertainty in each noise parameter. Results are presented for the noise parameter uncertainties for different values of the underlying measurement uncertainties.
