[SENSe<Ch>:]CORRection...
This subsystem controls system error correction and recording of correction data.
[SENSe<Ch>:]CORRection:CDATa 'DIRECTIVITY' | 'SRCMATCH' | 'REFLTRACK'
| 'ISOLATION' | 'LOADMATCH' | 'TRANSTRACK' | 'G11' | ... 'G22' | 'H11' | ... | 'H22',
<port1_no>, <port2_no>
Writes or reads system error correction data for a specific channel <Ch>, calibration method
([SENSe<Ch>:]CORRection:COLLect:METHod:DEFine), and port combination <Port1_no>,
<Port2_no>. The setting command can be used to transfer user-defined correction data 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])
For an overview of calibration methods and error terms refer to section Calibration Types.
<Ch> Channel number of the calibrated channel. If unspecified the numeric
suffix is set to 1.
Error term
parameters String parameters describing the different error terms, depending on the
current calibration method; see table below. Each term contains one
complex value (real and imaginary part) for each sweep point.
Range [def.
unit]
The error terms consist of dimensionless complex numbers. The
parameters must be transferred in full length and have the following
meaning:
'DIRECTIVITY' – Directivity at port <port1_no>
'SRCMATCH' – Source match at port <port1_no>
'REFLTRACK' – Reflection tracking at port <port1_no>
'ISOLATION' – Isolation between port <port1_no> and <port2_no>
'LOADMATCH' – Load match at <port2_no>
'TRANSTRACK' – Transmission tracking between port <port1_no> and
<port2_no>
'G11' ... 'G22' – G matrix elements, referenced to <port1_no>
(irrespective of the values of <port1_no> and <port2_no>)
'H11' ... 'H22' – H matrix elements, referenced to <port2_no> (irrespective
of the values of <port1_no> and <port2_no>)
*RST value –
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
.
<port1_no> Source port number. If the error term is not related to the source port, a
dummy number can be used; e.g.
CORR:CDAT 'TRANSTRACK', 0,1
<port2_no> 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
SCPI,
Command
Types Device-specific, command or query
After a system error correction in one of the sweep types Power,
Time, or CW Mode, the query returns two sets of correction data,
corresponding to the fixed CW frequency and the CW frequency
plus 1 Hz (minus 1 Hz if the CW frequency is equal to the
maximum frequency of the analyzer).
