D1, D2
The "D1" and "D2" buttons are enabled as long as the selected
subnetworks that are defined via two-port or four-port Touchstone files (
*.s2p
,
*.s4p
).
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 to select and run a third-party fixture modeling tool (see
ter 6.14.5, "Fixture Modeling Dialog"
on page 571) and to use its results for balanced
deembedding.
If the related tool is not available on the instrument, the "Run Model" buttons will be
disabled/grayed out. Use the "Info" button to get additional information about the
selected tool.
For background information, see
Chapter 5.6.2.9, "Fixture Modeling and Deembed-
Note:
before running the modeling tool.
6.14.8
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)
