Managing OCA Test Results

The graph will also display a dotted line across the full spectral width
corresponding to the peak detection level indicator. This line indicates the
minimum power level (dBm) from where a peak can be considered as a
valid signal.

A peak detection level cursor is available in the graph when the Results tab
is selected. The cursor is positioned along the Y-axis in accordance with
the channel plan default peak detection level analysis parameter.

You can move the cursor to modify the peak detection level for the current
measurement. Each time the cursor is moved, the trace is fully analyzed
again using the currently selected channel plan.

Note: If you select another tab than Results, the cursor disappears, but you can

still see the peak detection level indicator line.
