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
Port assignment for two 2-port (*.s2p) files:
PMAin - Port 1
PSECondary - Port 2
The ports must be specified for the import of 2-port (*.s2p)
files; they must be omitted for 4-port (*.s4p) files.
<Interchange> FPORts | IPORts | SGATes | SINCreasing
FPORts (or omitted)
Standard port sequence (odd port numbers towards VNA, even
port numbers towards DUT)
IPORts
– Two-port networks: inverted port sequence (network port 2
towards VNA, network port 1 towards DUT)
– Four-port networks: increasing port sequence (low port num-
bers 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)
Example:
*RST; SOUR:LPOR1 1,2; LPOR2 3,4
Define a balanced port configuration.
CALC:TRAN:VNET:BAL:EMB:TND STSL
Select the "Serial .s2p data, shunt L" circuit model.
MMEM:LOAD:VNET:BAL:EMB2 'C:
\Users\Public\Documents
\Rohde-Schwarz\Vna\VNET\Test.s2p', PMA
Load a Touchstone file and assign it to logical port no. 2.
Manual operation: See "File Name <i>/Swap Gates" on page 575
MMEMory:LOAD:VNETworks<Ch>:DIFFerential:EMBedding<LogPt>
<TouchstoneFile>[, <Interchange>]
Loads data of a Differential Match Embedding network from the specified Touchstone
*.s2p file.
Use CALCulate<Ch>:TRANsform:VNETworks:BALanced:EMBedding<LogPt>:
PARameters:DATA<Port> to load circuit data from the remote client instead.
The query returns the name of the loaded file.
