R&S ZNB/ZNBT
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.
Select Predefined Port
Allows you to select from a set of predefined logical port configurations.
The available configurations depend on the number of analyzer ports.
Remote command:
SOURce<Ch>:LPORt<LogPt>
SOURce<Ch>:LPORt<LogPt>:CLEar
Logical Port Config tab
The "Logical Port Config" tab of the "Balanced Ports" dialog allows you to configure
logical ports (balanced or unbalanced) and to disable unused physical ports in the
active channel.
This tab is only visible if more than 4 ports are available (on the VNA and/or connected
switch matrices).
Define Physical to Logical Port Relation
Allows you to define balanced, single-ended, and unused ports and provides functions
for (re)numbering the resulting logical ports.
In principle, it is possible to combine any pair of two physical analyzer ports into a bal-
anced port. With n test ports a maximum of n/2 (n even) or (n – 1)/2 (n odd) logical
ports is supported.
