Use CALCulate<Ch>:TRANsform:VNETworks:PPAir:DEEMbedding<ListId>:
TNDefinition or CALCulate<Ch>:TRANsform:VNETworks:PPAir:
EMBedding<ListId>:TNDefinition to select the desired circuit model before
loading the data files.
●
For any n-port set, the FIMPort model requires a single *.s<2n>p file and hence
a single set command.
●
For 2-port sets (port pairs), the circuit models STSL | STSC | SLST | SCST
require 2 *.s2p files, that have to be assigned to the appropriate port using two
set commands.
Suffix:
<Ch>
.
Channel number
<ListId> Index of the port set within the channel's overall list of port sets
for deembedding.
Parameters:
<TouchstoneFile> String parameter specifying the name and directory of the loa-
ded Touchstone file.
If no path is specified, the analyzer searches the current direc-
tory, which can be set and queried using MMEMory:
CDIRectory
<Port> PMAin | PSECondary
For port pairs, <Port> assigns a 2-port (*.s2p) file to the appro-
priate port. PMAin corresponds to D1, PSECondary to D2 in the
circuit model pictograms for balanced ports
For an s<2m>p file with m>1, this parameter is ignored. How-
ever, it must be specified unless the <Interchange> parameter is
also omitted.
<Interchange> FPORts | IPORts | SGATes | SINCreasing
Defines how to interpret the (implicit) port numbering of the
Touchstone file in the context of the deembedding network.
FPORts (or omitted)
Standard interpretation: odd port numbers towards VNA, even
port numbers towards DUT
IPORts
For s2p files IPORts means "inverted port sequence": network
port 2 towards VNA, network port 1 towards DUT
For s4p files IPORts means "increasing port sequence": low
port numbers towards VNA, high port numbers towards DUT
SGATes
Swapped gates: even port numbers towards VNA, odd port
numbers towards DUT
SINCreasing
Swapped increasing port sequence: high port numbers towards
VNA, low port numbers towards DUT
