[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
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.
<TestPort1>
Test port numbers. For an n-port automatic calibration, n arbi-
trary (not necessarily consecutive) port numbers must be speci-
fied.
<CalUnitPort1> Port numbers of the cal unit. For an n-port automatic calibration,
n arbitrary (not necessarily consecutive) port numbers must be
specified. It is possible to combine arbitrary (not necessarily
matching) pairs of analyzer and cal unit ports.
<TestPort2>
Example:
CORR:COLL:AUTO:PORT '', 1, 2, 2, 4, 4, 1
Perform an automatic 3-port calibration at the analyzer ports 1,
2, and 4 using the calibration unit's default calibration kit file and
ports 2, 4, and 1 of the cal unit.
Usage: Setting only
