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:
³
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 51).
³
reanalyze a trace acquired with a previous version of the software.
³
re-create the events table if it was modified.
³
perform a Pass/Fail test, if enabled (for more information, see Setting
Pass/Fail Thresholds on page 53).
When you reanalyze a trace acquired in Template mode:
³
Events copied from the reference trace (identified by “*”) will be lost.
³
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 153.
