Defining Traces

Agilent 86038B Photonic Dispersion and Loss Analyzer, Second Edition
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 DGDtrace for Port 1.
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 1 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 1 and DGD as the
measurement type.
7 Press Close to save the trace definitions.
For each trace you can specify any active port's measurement
traces and one of nine measurement types.
• GD (Group Delay)
• CD (Chromatic Dispersion)
• DGD (Differential Group Delay)
• PDL (Polarization Dependant Loss)
• Gain/Loss
• PCD (Polarization Dependent CD)
• Depol. Rate (Depolarization)
• 2nd Order PMD
• Optical Phase
Select Active Trace
From the Navigation area, press Next Trace until the desired
graph and trace tab are highlighted (that is, shown in white).
Toggling Between Graph Views
From the Navigation area, press Change View until all four
graphs are shown on the display.
