Simple loading
The key View Trace(s) enables simple loading of traces, using the current parameters
of the MTS/T-BERD or OneAdvisor-800. The current trace is then replaced with this new
trace.
Load with configuration
T he key Load Trace + Config will display the traces, recalling the configuration
recorded in the file. Thus the zooms, cursors and parameters present at the time of
acquisition will be used for the display.
This function also enables to recall and set the parameters defined in the screens corre-
sponding respectively to the File and Setup
keys.
It is then possible to perform an acquisition under the same conditions as those of the
trace recalled.
• If the product was equipped with a different module from the current one when
the trace was acquired, certain configuration parameters cannot be updated. A
message warns the user of this.
• If several traces are selected, the configuration used will be that of the first trace.
• If the number of traces added and the number of traces present is greater than 8,
then the last traces added will not all be taken into account.
Loading several traces in overlay
Up to 18 traces in the same application (OTDR) can be displayed simultaneously in
overlay.
To obtain a display of multiple traces, two methods are possible:
• Select all the files to be loaded at the same time and click on Load > View
Trace(s)
• Define a reference trace in a first time, open it, then come back to the explorer to
select the other traces to be added (see
“Reference Trace function” on page 70 ).
The configuration cannot be recalled if the trace was not originally cre-
ated by the equipment.
