R&S ZNB/ZNBT
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 the calibrated ports.
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.

Characterization
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

For an inline calibration system, each connected inline calibration unit has its own set
of characterizations:
Tip: If the characterization wizard is password-protected, the "Characterization" button
is unavailable. Use this functionality to prevent inadvertent activation of inappropriate
characterizations. See
