Trace Measurement and Processing of Existing Traces
Note: After a certain period of time, the trace displays on the GUI. The trace in the figure
below is a trace during measurement, which will be refreshed for every certain period of time
to.demonstrate.the.whole.process.in.realtime..But.at.the.end.of.measurement.the.trace.will.be.
complete,.as.shown.in.Figure.4-4.
Manual Trace Measurement
To achieve optimal measurement results, set the parameters manually.
1. Set the range. Refer to "Range Configuration" in Section 3.
2.. Press.Run/Stop.to.start.the.measurement..The.process.is.the.same.as.with.auto.measurement.

Live Traffic Warning

If the 920XC is connected to a fiber with live traffic, the warning of "Traffic Signal Detected!"
will.be.displayed.after.Run/Stop is activated. Disconnect the fiber under test and quit the
measurement. To avoid damage to the 920XC, ensure that live traffic is removed from the test
fiber before reconnecting to the 920XC.
Reasons for Trace Measurement Failures
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 fiber.
• Low SNR: Use a wider pulse or increase average time and try again.
• Incorrect parameter configuration: Check the parameter configuration and try again.
