Managing Spectral Transmittance Test Results

When the acquisition is taken (see Starting a Measurement on page 237 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. This reference RBW is shown
at the bottom of the graph.

If the current trace was previously saved, the graph will display the file
name of the current trace in the title bar.
