In case the port number conventions of the loaded two-port Touchstone file differ from
network analyzer conventions (port 1 on the left, i.e. on the analyzer side; port 2 on the
right, i.e. on the DUT side), it is possible to "Swap Gates". The analyzer will inter-
change the port numbers (e.g. S
12
--> S
21
) when loading the file.
Note: The loaded file is stored in the active recall set. 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 2-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 242) 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.
Remote command:
CALCulate:FMODel:DEASsistant:TOOL
5.14.5 Fixture modeling dialog
Allows you to model a test fixture using the selected fixture modeling tool and to deem-
bed selected ports using the generated touchstone files.
