Managing WDM Test Results
The noise level for a channel is indicated by a dotted line under the
selected peak. The width of the noise level indicator is set according to the
current Noise for OSNR setting. The width of the noise level indicator
depends on the noise associated with the OSNR setting (from the largest to
the narrowest): IEC, InB, InB nf and fit.
A dotted line across the full spectral width corresponds 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 application's peak detection level global analysis parameter.
