The De-Embedding Dialog - Teledyne T3SP Series Operator's Manual

Figure 11: Decomposition of overall system into subcomponents
•
The S-parameters of the fixtures and DUT are internally converted to
T-parameters.
•
The inverses of the fixture T-parameters are multiplied from the left
and right by the overall system T-parameters.
•
The result describes the DUT exclusively and is converted back to S-
parameters.
In summary, it is necessary to provide the software with the S-parameters
(see section 7.2) of the fixtures for the de-embedding task. The S-parameters
can either be made available by the supplier of the fixture or be determined
by the user. The determination of these parameters is far from trivial and
can be done by simulation or by measurement (or a combination of both).
The Seunis software itself can be used to characterize the adapters, please
refer to section 7.3.

7.2 The De-Embedding Dialog

Loading the S-parameters of the fixtures can be done via the De-Embedding
Dialog (see Fig. 12). The dialog can be opened via the tool button
