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.
