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.
For background information, see Chapter 5.5.5, "Automatic Calibration", on page 166.
Remote command:
SYSTem:COMMunicate:RDEVice:AKAL:ADDRess:ALL?
SYSTem:COMMunicate:RDEVice:AKAL:ADDRess
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 Chapter 6.11.2.3, "Characterize Cal Unit
Dialog", on page 483. By default, the R&S ZNB/ZNBT uses the last generated cal unit
characterization.
Tip: If the characterization wizard is password-protected, the "Characterization" button
is unavailable. Use this functionality to prevent inadvertent activation of inappropriate
characterizations. See "Authentication" on page 484.
See also Chapter 5.5.5.3, "Characterization of Calibration Units", on page 170.

Calibration Type / Source
Selects the calibration type for the selected physical ports. For an overview, refer to
Table 5-7.
The reflection calibration types can be used for any combination of physical ports:
reflection calibrations are performed for each selected port.
A transmission calibration type requires at least two physical ports. For the unidirec-
tional transmission calibration types ("Trans Norm", "One Path Two Ports"), the direc-
tion ("Source" port) must be specified in addition.
