 VB Syntax

data = calSet.getErrorTerm (setNumber, term, rcv, src)

Variable

(Type) - Description

data

(Variant) Two-dimensional safe array to store the returned data. Memory for the returned Variant is allocated by the VNA and must be released by client.

Note: See also getErrorTermComplex on the ICalData2 interface to avoid using the variant data type.

calSet

A 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 As NaErrorTerm2). Choose from:

0 - naET_Directivity           (rcv = src)

1 - naET_SourceMatch     ( rcv = src)

2 - naET_ReflectionTracking   ( rcv = src )

3 - naET_TransmissionTracking  (rcv ¹ src)

4 - naET_LoadMatch  ( rcv ¹ src)

5 - naET_Isolation  (rcv ¹ src)

rcv

(Long) - Receiver Port

src

(Long) - Source Port

Return Type

Variant

Default

Not Applicable

Examples

Dim varError As Variant
varError = CalSet.getErrorTerm(0,naET_TransmissionTracking,2,1)
