Setting Up EDFA Analysis Parameters
This section presents the various analysis settings for the application,
particularly the channel list and settings. You can set the channel list,
channel parameters, manage favorite configurations and perform user
calibration.
Note: When you change the analysis setup parameters, the new settings are
active as soon as you confirm your choice. The current trace is re-analyzed,
and the analysis setup parameters will be applied to the global results and
channel results for the following acquisitions.
You can either set each parameter individually, or use parameters from the
current trace and import them.
