If the "Fixture Simulator" is disabled for the related channel (see "Fixture Simulator"
on page 600), this tab is inactive, i.e. all controls except the "Overview" button are
grayed out.
Overview
See "Overview" on page 662.
Type
Switches between "Deembedding" and "Embedding" network definition.
Port Set
Port sets, defined in the complementary Port Sets panel dock widget panel. The trans-
formation networks are defined such that the physical analyzer test ports are connec-
ted to the left of the circuit; the DUT ports are on the right side. You can define inde-
pendent transformation networks for all port sets.
The port set number, i.e. the number at the beginning of each "Port Set" item, corre-
sponds to the position of the port set in the
Port Sets panel .
Remote command:
The port set number corresponds to the
<ListId>
numeric suffix in the port set de-/
embedding commands; see e.g.
CALCulate<Ch>:TRANsform:VNETworks:PPAir:
DEEMbedding<ListId>[:STATe]
.
All Deembedding Activated
Deactivates or activates all deembeddings (single-ended, balanced, port set, ground
loop) for the active channel, if any.
This control is only visible if Type = "Deembedding".
Network
Depending on the size m of the selected port set, the graphical list contains all availa-
ble 2 m -port deembedding/embedding networks.
Note: For port pairs (m=2) the deembedding/embedding network can be defined either
via lumped element models (in combination with
s2p
Touchstone files) or via a
s4p
Touchstone file (see Chapter 4.6.2.5, "Port pair de-/embedding" , on page 211). For
m≥3, there are no predefined lumped element models available; the deembedding/
embedding network has to be defined via an s<2m>p Touchstone file.
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
D1,
D2 .
For 4-port networks that are (partly) defined by lumped elements, the lumped element
parameters are displayed below the graphical network list. See
Chapter 4.6.2.4, "Cir-
cuit models for 4-port networks" , on page 210.
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.
