5.2.4 Trace Measurement — Reasons of Measurement Failures
If measurement failures occur, reasons may be one of the following:
•
Events may be too close to each other.
Shorten the pulse width, and make another try. If failure still occurs, please try
to measure at the other end of the optic fiber.
•
Low SNR.
Try to use wider pulse or increase average time, and make another try.
•
Incorrect parameter configuration.
Check parameter configuration, and make another try.
