Selecting the Displayed Wavelength
Selecting the Displayed Wavelength
There are two ways of displaying a trace in the OTDR test application.

You can switch from one wavelength to another. All wavelengths
appear on the graph but the current trace is displayed in black. You can
view all the trace files you have opened including main and reference
traces.
The table below shows the possible colors.

You can also hide traces and display the current trace only.
To display traces in turn:
Tap
or to switch between the main and reference traces.
To display only the current or all wavelengths:
Tap .
Note: In the Events and Summary tabs, the information displayed will behave
accordingly.
Note: Hiding a trace has no impact on the pass/fail status or the result values.
