Figure 5-33: Define Calibration dialog (MultiCal, Inline Calibration System)
Ports
Selects the test ports to be calibrated.
It is possible to select any combination of two or more test ports. If you are only inter-
ested in a single port
p
, perform a two-port SMARTerCal for a port pair including
p
(as
Power Port).
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.
Remote command:
The port parameters in many calibration commands define ports to be calibrated.
Cal Unit
Displays the connected calibration units. The R&S
ZNB/ZNBT auto-detects all calibra-
tion units which are connected to one of its USB ports. If several cal units are connec-
ted, one of them must be selected for calibration (active cal unit). A warning is dis-
played if the current sweep range of the network analyzer exceeds the characterized
frequency range of the calibration unit.
