OSA/OCA 177

Managing WDM Test Results

When the acquisition is taken (see Starting a Measurement on page 153 for

details on how to perform a test), the active trace will be displayed in the

tab with information along the following axis values:

 X axis: wavelength in nm or frequency in THz.

 Y axis: optical power expressed in dBm, as measured in the optical

resolution bandwidth (RBW) of the OSA/OCA. This reference RBW is

shown at the bottom of the graph.

If the current active trace was previously saved, the application will display

the file name of the current trace in the status bar.

The graph will display peak indicators for all the channels found by the

application with a red vertical line over the peaks to indicate the peak

position.

A blue horizontal bar ( ) will be displayed on the top of a channel if it

does not overlap with another channel. If the channel overlaps with

another channel, the horizontal bar will be yellow ( ).
