Using the Discover Feature
The Discover feature allows you to start a measurement procedure to
automatically build an analysis setup (scan range, channel list, analysis
parameters, etc.) based on the signal being detected on the input port of
the module.
Note: The Discover features is available on the WDM and Drift test modes only.
The procedure starts with a full range single scan (1250 nm to 1650 nm) to
determine signal spectral range. It is followed by a second scan to establish
the analysis parameters by locating the various peaks from the incoming
signal.
When the discover process is successful, the application displays the
results and graph for the detected channels and the newly discovered
analysis parameters are applied automatically to the analysis setup.
Note: If no signal is detected with the first scan, then the graph shows the full
range scan and ends the discover procedure. The application analysis
parameters remain unchanged.
