Example: Prerequisite:
SYSTem:COMMunicate:RDEVice:AKAL:ADDRess
'MyCalU'
Sets 'MyCalU' as the active calibration unit.
SYSTem:COMMunicate:RDEVice:AKAL:PORTs? 'abc'
Queries the ports of characterization 'abc'; returns something like
'3,N 50 Ohm,MALE,4,N 50 Ohm,MALE'. In particular, ports 1 and
2 are not yet characterized.
SENSe:CORRection:COLLect:AUTO:CKIT:PORTs:ADD
'abc',1,2
Extend characterization 'abc' with test port 1 assigned to port 2 of
the cal unit.
SYSTem:COMMunicate:RDEVice:AKAL:PORTs? 'abc'
Now returns something like '2,N 50 Ohm,MALE,3,N 50
Ohm,MALE,4,N 50 Ohm,MALE'.
Usage: Setting only
[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 connected
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

Suffix:

Channel number of the calibrated channel
Setting parameters:
<Characterization> Name and (possibly) directory 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 denotes a spe-
cific cal kit file stored in the active calibration unit.
–
A VNA cal kit file name
*.calkit
with path denotes a specific
cal kit file stored in an arbitrary directory.
<TestPort1> Test port numbers. For an n-port automatic calibration, n arbitrary
(not necessarily consecutive) port numbers must be specified.
<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>
