Predefined Config tab
The "Predefined Config" tab of the "Balanced Ports" dialog provides the most com-
monly used logical port configurations of the analyzer.
The port configurations are arranged in the list to the right. The resulting port assign-
ment is shown on the left-hand side of the "Predefined Config" tab.
●
For a single-ended port, the diagram shows a single line between the physical test
port and the logical port.
●
For a balanced port, two physical ports are combined to form a single logical port.
●
For unused ports, the physical port is crossed out; no logical port number is
assigned.
