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].

Network

Depending on the size m of the selected port set, the graphical list contains all availa-

ble 2m-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 5.6.2.5, "Port Pair De-/Embedding", on page 194). 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 5.6.2.4, "Cir-

cuit Models for 4-Port Networks", on page 193.

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.
