works known from balanced port de-/embedding, however, each transformation net-
work is assigned to an arbitrary pair of (single-ended) physical ports.
A simple circuit which can be modeled using port pair (de-)embedding is a circuit (e.g.
a resistance) between two ports of a DUT. To obtain the circuit in the following figure,
select port pair 1,2 and the Serial Ls, Shunt L transformation network with all inductan-
ces set to zero (L1 = L2 = L3 = 0 H) and R1 = R2 = 0 Ω.
To model a general (de-)embedding network for ports 1 and 2, select port pair 1,2 and
a 4-Port Touchstone file.
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

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).
