About Cal Sets

OpenCalSet Method   Superseded

Description

This command is no longer necessary. The CalSet.get... and put... commands that required this command have been replaced,

Open the Cal Set to read/write a particular CalType. Learn more about reading and writing Cal Data using COM.

This method is a prerequisite to several other Cal Set methods.

A Cal Set can contain more than one CalType. This method opens the Cal Set and allows access to a particular set of terms. Subsequent commands like getErrorTerm use this information to access the correct error terms in the Cal Set.  For example:

cset.OpenCalSet (naCalType_TwoPortSOLT,3,2)
cset.PutErrorTerm(naDirectivity, 1, 1, Buffer)

The directivity error term for port 1 could belong to any number of caltypes: Full1Port (S11), Full2Port (12), Full2Port (13) or Full3Port (123). The CalType and port specifiers in OpenCalSet directs the uploaded directivity term to the correct set of error terms.  

To close the Cal Set, see CloseCalSet.
