6.2.1
S-Params Tab
Selects S-parameters as measured quantities. S-parameters are the basic measured
quantities of a network analyzer. They describe how the DUT modifies a signal that is
transmitted or reflected in forward or reverse direction. S-parameters (and derived
quantities such as Y- and Z-parameters) fully characterize a linear DUT.

S-Parameter (selector)
as a measured quantity for the active trace.
Single-ended (unbalanced) S-parameters are referred to as S<out>< in>, where <out>
and <in> denote the output and input
logical
port numbers, respectively.
If entered manually, <out> and <in> must be expressed using the same number of dig-
its. I.e. for <out>=10 and <in>=9 you can specify S<out>< in> as S1009 or S010009,
but not as S109. For a channel setup with n single-ended ports, n
2
single-ended S-
parameters can be measured.
In presence of balanced ports, standard S-parameters are defined in the form
S<m_out><m_in><out><in>, where output mode <m_out> and input mode <m_in> can
be one of:
●
d (differential, balanced)
●
c (common, balanced)
●
s (single-ended, unbalanced)
It is also possible to display "raw" single-ended S-parameters within the same channel:
after setting the S-Parameter type to "S" any pair of (used)
physical
ports can be
selected.
