Analysis GetCorrectedIlTrace
Description This method returns a calculated trace where an offset is
applied to an acquired trace.
Syntax object.GetCorrectedIlTrace (DriftTrace, IlResultTrace) As Variant
Parameters DriftTrace: Required. A Variant value containing a
two-dimensional array representing pairs of X,Y coordinates of
the trace to set. Normally, you should provide the DriftTrace
retrieved through the use of the GetDriftTrace method.
IlResultTrace: Required. A Variant value containing a
two-dimensional array representing pairs of X,Y coordinates of
the trace to set. The IlResultTrace parameter should be a
previously acquired trace coming from acquisitions done on the
DUTs.
Response This method returns a Variant value containing a
two-dimensional array representing pairs of X,Y coordinates of
the trace.
Note This method computes a trace where we apply an offset trace
(DriftTrace) to a resulting IL trace (IlResultTrace).
This method must manipulate both traces to obtain a matching
trace in terms of X,Y coordinates pairs. In some cases,
interpolation must be used to fit the traces.
Note that this method has been designed for IL-type traces only.
Use this method in conjunction with the following method:
GetDriftTrace.
