Table of results
Event marker when a measurement cannot be made. If an added
event is too close of an existing event, this icon appears on the
trace and on the table for the second event, but no measurement is
made : a manual measurement is necessary to have results for this
event.
End of launch cable: losses and distances are referenced from this
marker.
• The distance from the beginning of the fiber to the event, given in meters
(kfeet or miles).
• The attenuation loss of the event causes, given in dB.
• The event reflectance, if any, in dB (or ORL if an ORL measurement has been
performed).
• The slope value before the event.
• The section length, between the event marker and the previous marker.
• The total loss budget of the trace given in dB.
The Event Result Table is totally interactive and reflects the actual measurements
that you make. Whenever you carry out an operation on the acquired trace the
Event Result Table is immediately updated to show the result of the operation
you made.
When a reflective event is saturated, the maximum value is displayed with a >
sign. This indicates that the real reflectance is greater than the given value (e.g. >-
29.5 dB means that the reflectance could be -18 dB).
When the Results on trace is activated in the TEST SET UP menu, the loss,
reflectance and slope measurements are shown on the trace.
The reflectance of a ghost event is displayed in brackets on the trace.
Notes in table
To each event:
• a note (40 characters max) can be associated.
• an uncertainty indicator concerning the displayed result
They are displayed in the table, below the event line, if they are validated in the
"Test Setup" menu of the "Result", in the Remarks in Table option.
Notes
For each wavelength, a maximum of 16 notes are possible.
For each note 40 characters can be entered. When uncertainties are validated,
only the first 17 characters will be displayed or printed.
Note Each note is associated to an event. So, if this event is erased, the
note will be erased too.
To enter a note:
• in the table, choose the event
• press the <Expert> key
