The R&S ZNA's current implementation of the fixture modeling tool support assumes
symmetrical lead-ins and lead-outs.
4.6.2.10 Combining Several de-/embedding networks
The R&S ZNA allows you to select a combination of networks to be numerically added/
removed at different layers
●
2-port networks at single ended physical ports
●
4-port networks at pairs of single ended physical ports
●
4-port networks at balanced logical ports
●
1-port ground loop networks
●
2-port differential match embedding networks at balanced logical ports
The different steps for deembedding and embedding are carried out in the following
order:
