Define Physical to Logical Port Relation
Allows to defines balanced, single-ended, and unused ports andprovides 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.
●
To define a balanced port, select two physical ports and tap "Balanced".
●
To dissolve balanced ports, select them and tap "Single".
●
To exclude logical ports from the measurement, select them and tap "Unused".
●
To (re-)assign a number to a logical port, select it and enter a new "Logical Port
Number" in the corresponding field
●
To number the logical ports in line with the physical ports, tap "Identity 1-1"
For balanced ports, the lower of the two physical port numbers is selected.
●
To number the logical ports consecutively from top to bottom, tap "Aligned 1,2,3..."
Remote command:
SOURce<Ch>:LPORt<LogPt>
SOURce<Ch>:LPORt<LogPt>:CLEar
User Config Tab
The "User Config" tab of the "Balanced Ports" dialog defines a new balanced port con-
figuration.
If more than 4 test ports are available (on the VNA and/or connected switch matrices)
this tab is replaced by the
tab.
