Testing Fibers in Advanced Mode

Although the application sets the acquisition parameters, you can modify
these values as needed, even while the acquisition is in progress. The
OTDR simply restarts the averaging each time a modification is made.
Note: You can interrupt the acquisition at any time. The application will display
the information acquired to that point.
Once the acquisition is complete or interrupted, the analysis starts for
acquisitions of 5 seconds or more.
After analysis, the trace is displayed and events appear in the events table.
For more information, see Analyzing Traces and Events on page 129.
The application will also display pass/fail messages if you have selected
this feature. For more information, see Enabling or Disabling Analysis After
Acquisition on page 76 and Displaying or Hiding Pass/Fail Messages on
page 114.
