Overview

Measuring power supply noise with spectrum analyzer:

Calibrate resolution for bandwidth accuracy for the best noise measurement results and optical power measurement results for wideband light sources. 

Smoothing attenuates excessive noise in a measured waveform.

The following types of data are recorded for WDM analysis and peaks.

• WDM analysis: Wavelength, level, SNR (signal-to-noise ratio)
• Peak: Wavelength, level
