<CorrectionData>...
[SENSe<Ch>:]CORRection:CDATa:PORT<PhyPt> <ErrorTerm>, <SourcePort>,
<LoadPort>, <CorrectionData>...
Writes or reads system error correction data for a specific channel <Ch>, calibration
method ([SENSe<Ch>:]CORRection:COLLect:METHod:DEFine), and port combi-
nation <SourcePort>, <LoadPort>. The setting command can be used to transfer
user-defined correction data <CorrectionData> to the analyzer; the query returns
the current correction data set. ASCII or block data can be transferred, depending on
the selected data transfer format (FORMat[:DATA]).
The sweep must be stopped to transfer calibration data; see program example for
[SENSe<Ch>:]CORRection:COLLect:SAVE:SELected:DEFault.
Note: This command affects the active calibration of channel no. <Ch> or the factory
calibration (if no channel calibration is active). For the factory calibration, the query
form is allowed only (no change of factory calibration data).
Tip: The analyzer provides a default calibration corresponding to a test setup which
does not introduce any systematic errors; see [SENSe<Ch>:]CORRection:
COLLect:SAVE:SELected:DEFault.
For an overview of calibration methods and error terms refer to Chapter 4.5.1, "Calibra-
tion types", on page 163.
G and H matrices
The 7-term calibration types named Txx (e.g. TOM, TRM, TRL, TNA) are based on a
network analyzer with two ports i and j, each equipped with a test receiver and a refer-
ence receiver. The system errors are described in terms of two "error two-ports" P
G
and P
H
:
●
The error two-port P
G
is assigned to port i of the analyzer. Its transmission matrix G
describes how the system errors modify the outgoing and incident waves at port i:
