Input 1, Input 2, Output 1, Output 2
Assign the ports to the input and output of the component according to the data in the
Touchstone file. This information is not directly written in the file. You need background
information how the S-parameters were determined, i.e. which port was input and
which port was output. If in doubt, the response curves help assigning the ports cor-
rectly.

Identical Paths
The setting is relevant if the measurement setup is a 4-port, and the component is a 2-
port. Usually, these components are cables and adapters, which are described by
*.s2p files. If there is a 4-port setup, 2 cables or 2 adapters are used. If there is no
crosstalk in-between, each cable or adapter can be described by a *.s2p file.
If both components are different, each is described by its own *.s2p file. If they are
identical, for example, when a matched-pair cable is used, they can be described by
the same file. In this case, enable "Identical Paths".

S-Parameters, Filetype
Loads the Touchstone file that contains the S-parameters of the component.
If the measurement setup is a 2-port, the filetype is always *.s2p.
If the measurement setup is a 4-port, the selection depends on the component. Fix-
tures and custom blocks are usually 4-ports, and they are described by *.s4p S-
parameter files.
Cables and adapters are usually 2-ports, and they are described by *.s2p S-parame-
ter files. If there is a 4-port setup, 2 cables or 2 adapters are used. You need 2 different
files if the components are different, or only 1 file if they are identical (see also "Identi-
cal Paths" on page 1070).
