Use CALCulate<Ch>:TRANsform:VNETworks:BALanced:
DEEMbedding<LogPt>:TNDefinition or CALCulate<Ch>:TRANsform:
VNETworks:BALanced:EMBedding<LogPt>:TNDefinitionto select the desired
circuit model before loading the data files.
●
The FIMPort model requires a single *.s4p file and hence a single set com-
mand.
●
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
<LogPt> Logical port number
Parameters:
<TouchstoneFile> String parameter to specify the name and directory of the loaded
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
Assigns a 2-port (*.s2p) file to the appropriate port. PMAin cor-
responds to D1, PSECondary to D2 in the circuit model picto-
grams.
For an s4p file, this parameter is ignored. However, 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 de-/embedding 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
