MMEMory:LOAD:VNETworks<Ch>:PPAir:EMBedding<ListId>
<arg0>[, <Port>,
<Interchange>]
Loads data from the specified Touchstone file (partially or completely) defining a port
pair circuit model for embedding. Select a port pair with a circuit model involving file
import before using the command.
Note
: Since V2.20 of the R&S
ZNB/ZNBT FW this command can also be used to load
an embedding network for port sets with m = 3 or 4 ports from a s<2m>p file.
Suffix:
<Ch>
.
Channel number
<ListId>
List index, denotes the current number of the defined pair of
ports within the list (see
VNETworks:PPAir:EMBedding<ListId>:DEFine
eral port pairs are defined, <ListId> is the number of the first port
pair.
Setting parameters:
<arg0>
String parameter to specify the name and directory of the loaded
Touchstone file. The port pair circuit models STSL | STSC |
SLST | SCST require two 2-port (*.s2p) files, to be assigned to
the different ports PMAin and PSECondary; the FIMPort model
requires a single 4-port (*.s4p) file but no additional port assign-
ment.
If no path is specified the analyzer searches the current direc-
tory, to be queried with
<Port>
PMAin | PSECondary
Port assignment for two 2-port (*.s2p) files:
PMAin
: Port 1
PSECondary
: Port 2
Must be specified for 2-port (*.s2p) files; must be omitted for 4-
port (*.s4p) files.
<Interchange>
FPORts | IPORts
Interchange port numbers of loaded
*.s2p
file:
FPORts
(or omitted): the port numbers are not interchanged
IPORts
: interchange port numbers
Example:
*RST; :CALC:TRAN:VNET:PPA:EMB:DEF 1,2,3,4
Define a port pair configuration with port pairs (1,2) and (3,4).
CALC:TRAN:VNET:PPA:EMB2:TND STSL
Select the
Serial Touchstone .s2p data, shunt L
circuit mode for
the second port pair.
MMEM:LOAD:VNET:PPA:EMB2 'C:
\Rohde-Schwarz\Vna\Traces\Test.s2p', PMA
Load a Touchstone file and assign it to the second port pair.
