Noise Correction Spectrum (Trace Data)
is the measured noise correction trace that will be applied when Noise Correction (Power Spectrum measurements) or IQ Noise Correction (non-Power Spectrum measurements) is turned on.
This spectrum represents the noise present in the analyzer for the current setup (measurement span/center, RF Radio Frequency: A generic term for radio-based technologies, operating between the Low Frequency range (30k Hz) and the Extra High Frequency range (300 GHz). Path, Preselector, etc.). This noise includes only noise that is uncorrelated to the signal.
Some hardware may only be able to highly attenuate the input instead of terminate. You can view the Noise Correction Spectrum to check whether any signal appears present in the measured noise spectrum. If so, you may need to use a lower signal power.
Noise correction may affect measurement speed. See Noise Correction or IQ Noise Correction for more information.
