Troubleshooting Flowcharts - JDS Uniphase SWS15100 User Manual

Problem
14 While making PDL
measurements, the PDL
shows only noise at all
wavelengths.
15
"Calibration Completed" is
not returned after the "Re-
Calibrate" button is pressed
during performance of
wavelength calibration.

Troubleshooting Flowcharts

The flowcharts in this section (Figure 105 to Figure 111) show the logical steps to use when
troubleshooting the SWS. Ensure that the system is correctly assembled and the procedures
described in the Installation, Testing the SWS Components, and Testing the System
sections of this manual are followed. The SWS Performance Checklist is used to record the
results of the testing, for reporting to the service hotline or the local JDS Uniphase
representative.
The following flowcharts are listed in this section:
•
Testing the systemsee the flowcharts in Figure 105 and Figure 106
•
Testing the SOMsee the flowchart in Figure 107
•
Testing the receiversee the flowcharts in Figure 108 and Figure 109
•
Testing for system noisesee the flowchart in Figure 110
•
Testing for SOM powersee the flowchart in Figure 111

Solution
If the problem persists:
•
Take another reference.
•
Acquire a new trace.
If the problem persists, contact the local JDS Uniphase
representative or the service hotline.
Verify re-calibration:
•
Open the SWS15100.INI file in the C:\Windows or
C:\WinNT directory.
•
Verify that the wavelengths of the two peaks are
entered correctly.
•
Verify that the values of Threshold1 and Threshold2
are low enough to ensure that the peaks can be
found.
•
If the values are not low enough, edit the
SWS15100.INI file.
•
Restart the SWS software.
•
Perform the wavelength calibration again.
If the problem persists, call the local JDS Uniphase
representative or the service hotline.
