Parameters:
<TouchstoneFile> String parameter specifying the name and directory of the loa-
ded Touchstone file.
The port pair circuit models STSL | STSC | SLST | SCST
require two s2p files, to be assigned to the different ports PMAin
and PSECondary. The FIMPort model requires a single s<2m>p
file (where m denotes the size of the port set), but no additional
port assignment.
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 port pairs:
PMAin: Main port (first port in port pair)
PSECondary: Secondary port
Must be specified for deembedding networks that are defined
using two s2p files (STSL | STSC | SLST | SCST); must be omit-
ted otherwise.
<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)
– 2m-port networks, m > 1: 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)
Example:
*RST; :CALC:TRAN:VNET:PPA:DEEM:DEF 1,2,3,4
Define a port pair configuration with port pairs (1,2) and (3,4).
CALC:TRAN:VNET:PPA:DEEM2:TND STSL
Select the Serial Touchstone .s2p data, shunt L circuit mode for
the second port pair.
MMEM:LOAD:VNET:PPA:DEEM2 'C:
\Rohde-Schwarz\Vna\Traces\Test.s2p', PMA
Load a Touchstone file and assign it to the second port pair.
Manual operation: See "File Name <i>/Inc. Seq. <i>" on page 574
