Comparison - Sept 2010
of the Noise Temperature of the LNAs for the Radioatronomy depend mainly
on the uncertainty of the instruments used to perform the measurement;
namely the Noise Source.
Even the most accurate Noise Source found on the market is often considered
not enough accurate for the radioastronomical purposes.
Once the Noise Sources has been calibrated with the most accurate metrological
standards, the only way to further improve the accuracy is a comparison.
Here you find the result of a comparison program of Noise Sources, performed
by trusted laboratories, around the Europe.
