[SENSe<Ch>:]CORRection:DATA 'SCORR1' | ... | 'SCORR12' | 'G11' | ... 'G22' |
'H11' | ... | H22'
[Deprecated command]
Writes or reads system error correction data for a specific channel <Ch> and calibration method
([SENSe<Ch>:]CORRection:COLLect:METHod). The analyzer test ports 1 or 2 are implicitly specified
with the correction terms. 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])
The sweep must be stopped to transfer calibration data; see program example for
[SENSe<Ch>:]CORRection:COLLect:SAVE:DEFault.
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).
Use the generalized command [SENSe<Ch>:]CORRection:COLLect:CDATa to transfer calibration
data for arbitrary analyzer ports.
Channel number of the calibrated channel. If unspecified the numeric suffix is set to
1.
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.
The error terms consist of dimensionless complex numbers. The parameters must be
transferred in full length and have the following meaning:
'SCORR1' – Directivity at port 1
'SCORR2' – Source match at port 1
'SCORR3' – Reflection tracking at port 1
'SCORR4' – Reserved for future extensions
'SCORR5' – Load match at port 2
'SCORR6' – Forward transmission tracking between port 1 and port 2
'SCORR7' – Directivity at port 2
'SCORR8' – Source match at port 2
'SCORR9' – Reflection tracking at port 2
'SCORR10' – Reserved for future extensions
'SCORR11' – Load match at port 1
'SCORR12' – Reverse transmission tracking between port 2 and port 1
'G11' ... 'G22' – G matrix elements
'H11' ... 'H22' – H matrix elements
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
reference 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:
