●
Starting with FW version 2.10, uncalibrated ports were disabled in the related
channel(s). If only one of the physical ports forming a balanced port was calibrated,
the balanced port was dissolved and only the uncalibrated (single-ended) port was
disabled.
In earlier FW versions there was no such port deactivation mechanism.
●
Since FW version 2.40 an uncalibrated port is only disabled if it is not used by a
measurement, i.e. if it is not required by any trace of the related channel.
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.
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.
