Displayed Columns
Opens a dialog to customize the Port Configuration table and display or hide columns.
• (Un)checking Logical Port, Source or Receiver displays (removes) the corresponding sections
in (from) the Port Configuration table.
• (Un)checking one of the second-level boxes displays (removes) the corresponding column in
(from) the Port Configuration table.
The physical port number is always displayed. The logical port information is displayed only if a
balanced port configuration is defined.
Remote control:
No command, display configuration only.
Balanced and Measured Ports
Opens a dialog to select a balanced port configuration and define reference impedances for balanced
ports and to select the measured ports.
Balanced and Measured Ports
Selecting a balanced port configuration means that one or more pairs of physical test ports are
combined to form logical (balanced) ports.
Balance-unbalance conversion is the simulation of one or more balance-unbalance transformers
(baluns) integrated in the measurement circuit in order to convert the DUT ports from an unbalanced
state into a balanced state and virtually separate the differential and common mode signals. The
analyzer measures the unbalanced state but converts the results and calculates mixed mode
parameters, e.g. mixed mode S-parameters. The balanced ports of the DUT are directly connected to
the analyzer ports and no physical transformer is needed.
