Manual Trace Measurement
To achieve optimal measurement results, set the parameters manually.
1. Set the range. Refer to “Range Conguration” in Section 3.
2. Press Run/Stop to start the measurement. The process is the same as with auto measurement.
Live Trafc Warning
Connect the optical ber directly to the 930XC optic output. No tools are required.If the 930XC is connected to a ber with live
trafc, the warning of “Trafc Signal Detected!” will be displayed after Run/Stop is activated. Disconnect the ber under test and
quit the measurement. To avoid damage to the 930XC, ensure that live trafc is removed from the test ber before reconnecting
to the 930XC.
Reasons for Trace Measurement Failures
Figure 4-5. Live Trafc Warning
If measurement failures occur, the reason may be one of the following:
• Events may be too close to each other: Shorten the pulse width and try again. If failure still occurs, try measuring at
the other end of the optical ber.
• Low SNR: Use a wider pulse or increase average time and try again.
• Incorrect parameter conguration: Check the parameter conguration and try again.
