Network
The 4-port deembedding/embedding network can either be defined via lumped element
models (in combination with
s2p
Touchstone files) or via an
s4p
Touchstone file (see
Chapter 8.6.2.5, "Port Pair De-/Embedding"
on page 270). For networks (partly)
defined by lumped elements, the lumped element parameters are displayed below the
graphical network list. See
Chapter 8.6.2.4, "Circuit Models for 4-Port Networks"
The symbol selects "no network" and disables de-/embedding for the selected port
set. The "D1" and "D2" networks are defined by imported S-parameter data; see
.
Tip:
●
Drag and drop the network symbols in horizontal or vertical direction to switch to
the next symbol. The lumped elements and S-parameter networks ("D1", "D2") are
numbered from top to bottom.
●
Use the
Conductance in Embedding Networks
switch to change from resistances
in "Capacitor in parallel with resistor" circuit blocks to conductances and vice versa.

D1, D2
The "D1" (and "D2") buttons are enabled as long as the selected deembedding/embed-
ding network is defined using Touchstone files.
When loading a touchstone file, the analyzer by default assumes odd ports left (VNA
side), even ports right (DUT side). However, it is also possible to instruct the analyzer
to assume an "Increasing Port Sequence", i.e. that the low port numbers are on the
VNA side. Furthermore it is possible to "Swap Gates", i.e. to instruct the analyzer to
swap the VNA and DUT side.
