Use
[SENSe<Ch>:]CORRection:COLLect:AUTO:CONFigure
to prepare an
automatic calibration with multiple port assignments.
Suffix:
<Ch>
.
Channel number of the calibrated channel
Setting parameters:
<Characterization> Location of the characterization (cal kit file) to be used for the
automatic calibration (string parameter):
–
If an empty string (
' '
) is specified, the factory cal kit file
stored in the active calibration unit is used.
–
A VNA cal kit file name
*.calkit
without path refers to a
specific cal kit file stored in the internal memory of the active cal-
ibration unit.
–
A VNA cal kit file name without path but prefixed with "SD:"
refers to a specific cal kit file stored on the SD card inserted at
the active calibration unit.
–
A VNA cal kit file name
*.calkit
with path refers to a spe-
cific cal kit file stored in an arbitrary directory on the analyzer.
<TestPort>
<TestPort> Test port numbers. For an n-port automatic calibration, n arbi-
trary (not necessarily consecutive) port numbers must be speci-
fied. The analyzer automatically detects the calibration unit ports
connected to each analyzer port.
Example: CORR:COLL:AUTO '', 1, 2, 4
Perform an automatic 3-port calibration at test ports 1, 2, and 4
using the calibration unit's default calibration kit file and arbitrary
test ports of the cal unit.
Usage: Setting only
Manual operation: See "Apply/Cancel" on page 269
[SENSe<Ch>:]CORRection:COLLect:AUTO:PORTs <Characterization>,
<TestPort1>, <CalUnitPort1>, <TestPort2>...
Selects and initiates an automatic calibration at arbitrary analyzer and calibration unit
ports. A progress monitor for the calibration sweeps is displayed.
Tip:
●
This command is necessary if the analyzer fails to detect the cal unit ports connec-
ted to each of its ports (e.g. because of a high attenuation in the test setup). If
auto-detection works you can use the simpler command
[SENSe<Ch>:
]CORRection:COLLect:AUTO
.
●
If several calibration units are connected, use
SYSTem:COMMunicate:RDEVice:
AKAL:ADDRess
to select a unit for the calibration.
Suffix:
<Ch>
.
Channel number of the calibrated channel
