Note: Calibration and port de-/activation.
The analyzer fimware automatically activates/deactivates ports during/after a (success-
ful) calibration:
●
Calibrated ports that were previously disabled, are automatically enabled as single-
ended logical ports.
●
An uncalibrated port that is not used by a measurement (i.e. the port is not required
by any trace of the related channel) is disabled.
Common Port ← Cal. Settings
For unidirectional 2-port calibrations such as "Trans Norm", the "Common Port" repre-
sents the source port.
For full n-port automatic calibrations with 3 or more ports, it defines the port that must
appear in each port assignment, and that are as the "center" of all Through measure-
ments.
In the latter case, the combo-box is only available if "Use Reduced Number of
Through" on page 667 is activated in the "Calibration" tab of the "System Config" dia-
log.
Remote command:
[SENSe<Ch>:]CORRection:COLLect:AUTO:CPORt
Power Meter ← Cal. Settings
Shows a list of all power meters that have been properly configured and are available
for the scalar source power calibration of a single source port. The last configured
power meter is selected by default. See
"Configured Devices" on page 690.
Remote command:
[SENSe:]CORRection:COLLect:PMETer:ID
Cal Kit <i> ← Cal. Settings
For each physical port covered by the selected calibration definition, you can select a
cal kit or cal unit. The drop-down list contains the kits for the selected connector type
and the connected calibration units.
The assignment of a calibration kit or unit to a connector type must be the same for all
physical ports covered by the calibration definition. If a calibration kit is changed, the
R&S
ZNA automatically assigns the new kit to all ports with the same connector type.
Use Import Cal Kit... to add new kits to the list.
Remote command:
[SENSe:]CORRection:CKIT:SELect
Characterization ← Cal. Settings
Displays all characterizations that are stored in the active cal unit. The "Factory" char-
acterization is available for all calibration units; it ensures an accurate calibration for all
standard applications. To account for modifications of the cal unit such as the connec-
tion of additional adapters, you can generate modified sets of characterization data
using the cal unit characterization wizard. See
Chapter 6.11.2.3, "Characterize Cal Unit
Dialog" , on page 482. By default, the R&S ZNA uses the last generated cal unit char-
acterization.
