R&S ZNB/ZNBT
When loading a touchstone file, the analyzer by default assumes odd ports left (VNA
side), even ports right (DUT side). However, it is also possible to instruct the analyzer
to assume an "Increasing Port Sequence", i.e. that the low port numbers are on the
VNA side. Furthermore it is possible to "Swap Gates", i.e. to instruct the analyzer to
swap the VNA and DUT side.
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.

Fixture Tool
The "Fixture Tool" section is only available for deembedding 4-port data networks.
Its controls allow you to select and run a third-party fixture modeling tool (see
ter 4.6.2.9, "Fixture modeling and
for single-ended deembedding.
If the selected fixture modeling tool is not installed on the instrument, the "Run Tool"
button is disabled/grayed out. Otherwise it opens the
guides you through the fixture modeling.
Use the "Info" button to get additional information about the selected tool.
Note: Define at least two
5.13.8 Ground Loop tab
Allows you to specify a 1-port ground loop deembedding/embedding network.
Such a network is either defined
●
via its S-parameter stored in a one-port Touchstone file (*.s1p) or
●
by selecting a predefined lumped element model (Shunt L or Shunt C) and specify-
ing the available parameters (resistance/inductance or resistance/capacitance)
Use the complementary dock widget to activate or deactivate ground loop dembedding
and embedding (see
If multiple port groups (DUTs)
enabled, use the dock widget to select the port group whose ground loop network shall
be configured.
