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 9.5.1, "Calibra-
tion types", on page 249.
Suffix:
<Ch>
.
Channel number of the calibrated channel.
Parameters:
<ErrorTerm> String parameters describing the different error terms, depend-
ing on the current calibration method; see table below. Each
term contains one complex value (real and imaginary part) for
each sweep point. The parameters must be transferred in full
length. The following strings are allowed:
'DIRECTIVITY'
Directivity at source port <SourcePort>
'SRCMATCH'
Source match at source port <SourcePort>
'REFLTRACK'
Reflection tracking at source port <SourcePort>
'LOADMATCH'
Load match at load port <LoadPort>
'TRANSTRACK'
Transmission tracking between source port <SourcePort> and
load port <LoadPort>.
Range:
The error terms are dimensionless complex num-
bers.
*RST: n/a
<SourcePort> Source port number
<LoadPort> Load port number. If the error term is not related to the load port,
a dummy number can be used; e.g. CORR:CDAT
'REFLTRACK', 1, 0
<CorrectionData> Correction data set (one complex number per sweep point) to be
transferred to the analyzer either in ASCII or block data format,
depending on the current FORMat[:DATA] setting. The correc-
tion data set is assigned to the specified channel, error term,
source and load port.
This parameter must not be used for queries.
Example: See [SENSe<Ch>:]CORRection:COLLect:SAVE:
SELected:DEFault.
The different calibration types of the analyzer provide the following error terms:
