The two port pair (de-)embedding networks in the figure below are based on port pairs
1, 2 and 1, 3 with appropriate sets of 4-port S-parameters.
The R&S ZNB/ZNBT FW handles Port Pair De-/Embedding as a special case of Port
set de-/embedding.

The port set de-/embedding feature allows de-/embedding a linear 2m-port network
connecting m physical VNA ports to m physical DUT ports (m≥2).
