Types
Device-specific, command or query.
Example:
*RST; SENSe1:CORRection:BCFReq:STATe?
Query the default state of "Cal and Corr at Base Freq". The response is 0.
[SENSe<Ch>:]CORRection:CDATa 'DIRECTIVITY' | 'SRCMATCH' | 'REFLTRACK' |
'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]).
The sweep must be stopped to transfer calibration data; see program example for
[SENSe<Ch>:]CORRection:COLLect:SAVE:SELected: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).
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 are 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>
'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>)
G and H Matrices
The 7-term calibration types named Txx (e.g. TOM, TRM, TRL, TNA) are based on a
