Suffix:
<Ch>
.
Channel number of the calibrated channel.
Example:
CORR:COLL:METH REFL1
Select a one-port normalization at port 1 as calibration type.
CORR:COLL OPEN1
Measure an open standard connected to port 1 and store the
measurement results of this standard.
CORR:COLL:SAVE
Calculate the system error correction data and apply it to the
active channel.
Usage:
Event
[SENSe<Ch>:]CORRection:DATA
<ErrorTerm>, <Parameter>...
Writes or reads system error correction data for a specific channel
<Ch>
and calibra-
tion 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 (
)
The sweep must be stopped to transfer calibration data; see program example for
[SENSe<Ch>:]CORRection:COLLect:SAVE: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:
to transfer
calibration data for arbitrary analyzer ports. The analyzer provides a default calibration
corresponding to a test setup which does not introduce any systematic errors; see
[SENSe<Ch>:]CORRection:COLLect:SAVE:DEFault
.
G and H matrices
The 7-term calibration types named Txx (e.g. TOM, TSM, 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:
