Analyzing or Reanalyzing a Trace
Analyzing or Reanalyzing a Trace
Note: This function is available in Advanced mode only.
You can analyze a displayed trace at any time. Analyzing or reanalyzing a
trace will:

produce an events table for a trace, if there was none (for example, the
Automatically Analyze Data after Acquisition feature was not selected;
see Enabling or Disabling Analysis After Acquisition on page 48).

reanalyze a trace acquired with a previous version of the software.

re-create the events table if it was modified.

perform a Pass/Fail test, if enabled (for more information, see Setting
Pass/Fail Thresholds on page 50).
When you reanalyze a trace acquired in Template mode:

Events copied from the reference trace (identified by “*”) will be lost.

The application will assign a number to the events that were identified
by question marks.
If you prefer to focus your analysis on a specific fiber span, see Analyzing
the Fiber on a Specific Fiber Span on page 151.
