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.
