provided, the reference plane shift is applied to the specified calibration only.
An error is raised if no system error correction is defined for channel <Ch> (using
[SENSe<Ch>:]CORRection:COLLect:METHod:DEFine). If the parameter <cal_name> is provided an
error is raised if a calibration with that name is not defined for channel <Ch>.
This command can not be used to shift the reference plane of existing NIST Multiline TRL calibration.
It rather stores the value to be used the next time such a calibration is applied using
[SENSe<Ch>:]CORRection:COLLect:SAVE:SELected. If the optional <cal_name> parameter is
provided, the referenced calibration must have been created prior to executing the command (either
through [SENSe<Ch>:]CORRection:COLLect:METHod:DEFine or MMEMory:LOAD:CORRection).
For an applied NIST Multiline TRL calibration (i.e. after
[SENSe<Ch>:]CORRection:COLLect:SAVE:SELected has been called) the reference plane shift can
be queried using the remote control command [SENSe<Ch>:]CORRection:DATA:PARameter<Cal>?
RPSHift.

Query syntax: [SENSe<Ch>:]CORRection:COLLect:RPSHift?
[<cal_name>]. Returns the reference plane shift to be used for a calibration. If the
optional <cal_name> parameter is missing the reference plane shift for the first NIST
Multiline TRL calibration of channel <Ch> is returned. If the optional parameter is
provided the reference plane shift to be used for the specified calibration is returned.
Example:
SENSe:CORRection:COLLect:METHod:DEFine 'Cal 1',NMTRl,3,4
Defines a NIST Multiline TRL calibration named 'Cal 1' at ports 3 and 4
SENSe:CORRection:COLLect:RPSHift 0.0014,'Cal 1'
Specifies a reference plane shift of 1.4 mm towards the DUT for 'Cal 1'
SENSe:CORRection:COLLect:RPSHift? 'Cal 1'
Returns the reference plane shift to be used for the calibration 'Cal 1' (1.4 mm)
[SENSe<Ch>:]CORRection:COLLect:SAVE
[Deprecated command]
Calculates the system error correction data from the acquired one or two-port measurement results
([SENSe<Ch>:]CORRection:COLLect[:ACQuire]), stores them and applies them to the calibrated
channel <Ch>. To avoid incompatibilities, older system error correction data is deleted unless it has been
transferred into a cal pool (MMEMory:STORe:CORRection <Ch>, '<file_name>').
This command is the ZVR-compatible equivalent of
[SENSe<Ch>:]CORRection:COLLect:SAVE:SELected. It must be used in combination with the ZVR-
compatible commands for calibration method and standard selection; see example below.
