GetErrorTermComplex Method   Superseded

Description

This command is replaced with Get ErrorTermComplexByString

Returns error term data from the Cal Set. The data is in complex pairs.

Note: This method exists on a non-default interface. If you cannot access this method, use the GetErrorTerm Method on ICal Set.

 VB Syntax

iCalData2.GetErrorTermComplex setNumber, term, rcv, src, numPts, real(), imag()

Variable

(Type) - Description

iCalData2

An ICalData2 pointer to the Cal Set object

setNumber

(Long) There can be more than one set of error terms in a Cal Set.

  • setNumber 0 contains the original set of error terms for a Cal Set.

  • setNumbers > 0 contain Interpolated error terms. Interpolated error terms are generated when interpolation is required and destroyed when no longer used. Learn about Interpolation.

  • To determine the setNumber in use by a channel, see GetCalSetUsageInfo

term

(enum NAErrorTerm2) - The error term to be retrieved. Choose from:

0 - naET_Directivity

1 - naET_SourceMatch

2 - naET_ReflectionTracking

3 - naET_TransmissionTracking

4 - naET_LoadMatch

5 - naET_Isolation

rcv

(Long) - Receiver Port

src

(Long) - Source Port

numPts

(Long) An In/Out parameter.

On the way in, you specify the max number of values being requested.

On the way out, the PNA returns number of values actually returned.

real()

(single) - array to accept the real part of the error-term. One-dimensional for the number of data points.

imag()

(single) - array to accept the imaginary part of the error-term. One-dimensional for the number of data points.

Return Type

Single

Default

Not Applicable

Examples

dim numpts as long
numpts = ActiveChannel.NumberOfPoints
ReDim r(numpts)  ' real part
ReDim i(numpts)  ' imaginary part
Dim CalSet as CalSet
set CalSet = pna.GetCalManager.GetCal SetByGUID( txtGUID )
Dim eData As ICalData2
Set eData = CalSet
eData.getErrorTermComplex 0, naET_LoadMatch, 1, 2, numpts, r(0),i (0)
