646User Manual 1173.9163.02 ─ 62

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.

Remote command:

MMEMory:LOAD:VNETworks<Ch>:BALanced:DEEMbedding<LogPt>

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 Chap-

ter 4.6.2.9, "Fixture modeling and deembedding", on page 217) and to use its results

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 Fixture modeling dialog that

guides you through the fixture modeling.

Use the "Info" button to get additional information about the selected tool.

Note: Define at least two Balanced panel before running the modeling tool.

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 Chapter 5.13.1.6, "Ground Loop panel", on page 612).

If multiple port groups (DUTs) are configured and Ground Loop per Port Group is

enabled, use the dock widget to select the port group whose ground loop network shall

be configured.
