Managing Drift 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.

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 ( ).
