Logical Port
Logical analyzer port, as defined in the "Balanced Ports" configuration. The transfor-
mation networks are defined such that the physical analyzer test ports are connected
to the left of the circuit; the DUT ports are on the right side. You can define independ-
ent embedding networks for all balanced ports.
Remote command:
The <LogPt> numeric suffix in the embedding/deembedding commands identifies the
logical port; see e.g.
EMBedding<LogPt>[:STATe].
Network
The graphical list contains the available 2-port networks for Differential Match embed-
ding:
●
The
the selected balanced port.
●
The "2-Port Data" network is defined by means of imported S-parameter data; see
Select File...
●
The "Shunt L, Shunt C" network is defined by lumped elements whose parameters
are displayed below the graphical list.
Tip: Drag and drop the network symbols in horizontal or vertical direction to switch to
the next symbol.

Select File...
"Select File..." is enabled as long as the "2-Port Data" network is selected. This net-
work is defined by its S-parameters stored in a two-port Touchstone file (*.s2p). No
additional parameters are required.
Note: The loaded file is stored in the active recall set. Persisted recall sets contain the
full (de-)embedding data so that they can be transferred to other instruments.
