Explanation

The following configuration is used to measure the input optical spectrum. 

 

 

 

Multi-channel light source

 

AQ6373

 

MUX

 

Optical amplifier

 

Measure the input optical spectrum and write the waveform to the active trace.

Setting Analysis Parameters

The OSNR (WDM) analysis function parameters may be broadly divided into the 
following three configurations. 
Parameter settings may be changed as desired according to the details of the particular 
analysis. 

•  Parameters related to channel detection (CHANNEL DETECTION SETTING)
•  Parameters related to noise level measurement (INTERPOLATION SETTING)
•   Parameters related to analysis results display method (DISPLAY SETTING)

These are explained below. See appendix 4, “OSNR (WDM) analysis Function” for a 
description of the parameters.
