●
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
ZNL/ZNLE 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 8.5.5, "Automatic Calibration"
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 9.12.2.4, "Characterize Cal Unit
on page 461. By default, the R&S
ZNL/ZNLE 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

Calibration Type / Source
Selects the calibration type for the selected physical ports. For an overview, refer to
.
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.
