Trace Display and Events Table Description

The application shows the analysis results both on a graph and in a table.
The events, that are detailed in the events table (see Event Pane on
page 131), are mark
ed by numbers along the displayed trace.

Some items in the trace display are always visible, while others will appear
only if you choose to display them. The contents of the graph area changes
according to the selected pane.

The light green rectangle on the Y-axis (relative powers) indicates the
proper injection level range for the defined test pulse. If the current
injection level is outside the appropriate range, the application will display
a warning message if you selected the first connector check feature (see
Enabling or Disabling the First Connector Check on page 54).
