How to Improve Noise-Figure Measurements and Calibrate High-Power Noise Sources (.PDF Download)

Those who have ever tried to manually measure an amplifier’s noise figure may have found that the numbers aren’t quite what was expected. This is most likely the result of the spectrum analyzer’s noise figure, which adds noise to the measurement. If an interfacing amplifier is needed to boost the device-under-test (DUT) output noise power above that of the spectrum analyzer’s noise floor, then it becomes even more likely that accuracy will suffer.
