DWDM Passive Component Test System 133
Monitoring Modules in Local Mode
Note: The first time you work with the system, the polarization state appears as
“Unknown State”. Use the Optimize Power button to get the system to
determine a valid polarization state (“Linear Horizontal”). Although it is
possible to optimize power at any time except when a test is running, be
aware that optimizing will result in the deletion of all the references that
were taken previously.
As soon as a valid state is displayed, you can modify it using the up and
down arrows if the one presented does not suit your needs.
³
A display zone that allows you to see the output power of the WRM
channels and of all the power meters, in dBm.
Note: For the WRM, channel 1 (Ch #1) corresponds to the power reference and
channel 4 (Ch #4) to the value read on the ORL detector.
When you are done with the settings, simply click Apply so the
modifications will be taken into account. Click Close to return to the main
window.
