Measurements do not necessarily require all of the physical and logical ports of the network analyzer.
To save measurement time, it is recommended to define the ports that are actually used in the current
test setup
(Define Measured Ports) . Unused ports will not be considered for the calculation of mixed
mode, Z- and Y-parameters.
In the four tabs of the Balanced and Measured Ports dialog it is possible to
•
Select one of the predefined balanced port configurations (Predefined Configs).
•
Define a logical port based on two physical ports and independent reference impedances for
the calculation of common mode and differential mode parameters
(Def. Balanced Port) .
•
Dissolve a single logical port so that the two involved ports are again used as physical ports
(Dissolve Bal. Port) .
•
Select the ports that can be used for the measurement (Define Measured Ports).
Predefined Configs
The Predefined Configs tab of the Balanced and Measured Ports dialog provides the most commonly
used balanced port configurations for the analyzer.
