S2P
Data Format
This format creates component data
files
that describe frequency dependent linear network
parameters for 2 port components These
hles
are assigned a
hlename
with the sulhx “S” and
are only outputted (that is, they cannot be read in by the analyzers).
Up to two
S2P
files
are saved: Sl for channel 1, and
S2
for channel 2.
S2P
files are not stored
for channel 3 or channel 4 because the data would be redundant. Each
S2P
file
contains
alI
four S-parameter data.
An
S2P
hle
is only outputted when the
ail
of following conditions are met:
