Note: If the measurement contains connector loss and splice loss for a merged
event, the loss value status and measurement status is calculated on the
basis of the selected thresholds. If thresholds are applied and the status is
pass, the measurement status is indicated as pass. If thresholds are applied
and the status is fail, the measurement status is indicated as unknown. If
none of the thresholds are applied, the measurement status is indicated as
unknown.
Note: When the span ORL value is preceded by a “<” and the ORL threshold is
smaller than or equal to the value, the global pass/fail status for the
measurement will be unknown or fail.
To view and modify a threshold value for the current
measurement:
1. From the Files or Measurement tab, select the measurement or
measurements as desired.
The current pass/fail threshold statuses are indicated in the list: green
for pass, yellow for warning and red for fail.
2. In the Results window, select the Thresholds tab.
