The main purpose of the default correction data set is to provide a dummy calibration
which you can partly replace with your own, external correction data. You may have
acquired the external data in a previous session or even on another instrument. If you
want to use the external correction data on the analyzer, simply generate the default
data set corresponding to your port configuration and calibration type and overwrite the
default data. For details refer to the program example below.
Tip:
Suffix:
<Ch>
.
Channel number of the calibrated channel.
Example:
CORR:COLL:METH:DEF 'Test',RSHort,1
Select a one-port normalization at port 1 with a short standard
as calibration type.
CORR:COLL:SAVE:SEL:DEF
Calculate a dummy system error correction for the normalization
at port 1. The dummy system error correction provides the
reflection tracking error term 'REFLTRACK'.
CORR:CDAT? 'REFLTRACK',1,0
Query the dummy system error correction term. The response is
a 1 (written as
1,0
for the real and imaginary part) for each
sweep point (no attenuation and no phase shift between the
analyzer and the calibration plane).
INIT:CONT OFF; :INIT; *WAI
Stop the sweep to ensure correct transfer of calibration data.
CORR:CDAT 'REFLTRACK',1,0,<ASCII_data>
Replace the dummy system error correction term with your own
correction data, transferred in ASCII format.
INIT:CONT ON
Restart the sweep in continuous mode.

Manual operation:
See
[SENSe<Ch>:]CORRection:COLLect:SAVE:SELected[:DUMMy]
Calculates the system error correction data from the acquired measurement results
(
[SENSe<Ch>:]CORRection:COLLect[:ACQuire]:SELected
), stores it and
applies it to the calibrated channel(s). To avoid incompatibilities, older system error cor-
rection data is deleted unless it has been transferred into a cal pool (
<Ch>, '<file_name>'
).
Suffix:
<Ch>
.
One of the calibrated channels
If
[SENSe:]CORRection:COLLect:CHANnels:ALL
is ON
this suffix can be omitted
