Defining Traces

The Define Trace function assigns a measurement on a specified port to a
specific trace on the graph. Up to two measurement traces can be
assigned to each of the four graphs.
The following example will show you how to assign the CD trace and the
DGD trace for Port 2.
1 From the Navigation area, press Change View until all four graphs are shown on
the display.
2 From the Navigation area, press Next Trace until the desired graph and trace tab
are highlighted (that is, shown in white).
3 From the Display area, press Define Trace.
4 In the Define Trace setup panel, select Port 2 and CD as the Measurement type.
5 From the Navigation area, press Next Trace to highlight the second trace tab on
the graph.
6 In the Define Trace setup panel, select Port 2 and DGD as the measurement type.
7 Press Close to save the trace definitions.
For each trace you can specify either Port 1 or Port 2 measurement traces
and one of five measurement types.
GD (Group Delay)
CD (Chromatic Dispersion)
DGD (Differential Group Delay)
PDL (Polarization Dependant Loss)
Gain Loss
Select Active Trace
