GetPdCwTrace
Description This method returns the trace associated with the minimum or
the maximum central wavelength values affected by the
polarization state of the signal.
Syntax object.GetPdCwTrace (PdCwTrace) as Variant
Parameters PdCwTrace: Required. A numeric value that corresponds to the
constant associated with the desired trace.
The table below shows the possible values with their
corresponding constants.
Response A Variant value containing a two-dimensional array representing
pairs of X,Y coordinates of the desired trace.
Note This method returns the trace that corresponds to an extreme
trace (representing the minimum central wavelength value or
the maximum central wavelength) that the analysis can find,
based on polarization state variations.
The central wavelength value is obtained from trace analysis.
Constant Value Description
Min 1 Retrieved trace will
correspond to the minimum
central wavelength values.
Max 2 Retrieved trace will
correspond to the maximum
central wavelength values.
