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
