Managing Channels
Testing DWDM systems involves characterizing multiple signals in a link.
The application allows you to define channels using a channel editor or
quickly generate them from the current data. You can also rapidly create a
list of equally spaced channels. Once a channel list is created, you can
modify it as needed. You can edit the analysis parameters for one channel
or multiple channels.
While creating the channel list, some channels may overlap. When the
channel widths are specified in nm, two channels are considered to be
overlapping when more than 1.2 GHz (approximately) of frequency range
is common between the two channels.
To add a channel list:
1. From the Main Menu, press Analysis Setup.
