●
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
True Differential Mode
Activates/deactivates True Differential Mode
This checkbox is only visible if True differential mode option R&S ZNA-K61 is available.
It is enabled, if at least one balanced port is configured, whose physical ports are fed
by independent sources (see Chapter 4.7.19, "Internal 3rd and 4th source for 4-port
R&S ZNA", on page 273). In case the balanced port is made up of frequency converter
ports, Power Control must be active for both of them.
Use the "Source Cohrence..." button to open the Source Coherence dialog dialog,
which allows you to configure the TruDi-specific sweep types.
Remote command:
SOURce<Ch>:TDIF[:STATe]
Source Coherence...
Opens the dialog of the same name, which allows you to configure and enable source
coherence and to configure the true differential mode sweep types "Phase Imbalance"
and "Amplitude Imbalance".
See Chapter 5.13.3.2, "Source Coherence dialog", on page 648.
User Config tab
The "User Config" tab of the "Balanced Ports" dialog defines a new balanced port con-
figuration.
