Parameters:
<Boolean>
Manual operation: See "Trim Leading Whitespace" on page 144
MMEMory:STORe:TRACe:PORTs <Channel>, <TouchstoneFile>, <Format>[,
<ModeImpedance>, <Port>[, <Port>]...]
Generates an snpTouchstone file, where n is the number of specified ports.
If ports 1 and 2 are specified and configured as balanced port, and if export of Bal-
anced Params is enabled, then the Touchstone file contains the full set of balanced S-
parameters. Otherwise, it contains the full set of single-ended S-parameters. Both sets
have a size of n
2
.
The command fails unless the conditions for Touchstone file export are met; see "Con-
ditions for Touchstone file export" on page 243. Traces are created using the
CALCulate<Ch>:PARameter:SDEFine command.
Setting parameters:
<Channel> Channel number in the active channel setup.
<TouchstoneFile> String parameter to specify the name and directory of the cre-
ated Touchstone file. The file extension *.snp for an n-port
Touchstone file is mandatory.
If no path is specified the analyzer searches the current direc-
tory, to be queried with MMEMory:CDIRectory?
<Format> COMPlex | LINPhase | LOGPhase
COMPlex - complex values (real and imaginary part).
LINPhase - Linear magnitude and phase.
LOGPhase - dB-magnitude and phase.
<ModeImpedance> CIMPedance | PIMPedance
CIMPedance (default, if omitted): normalize to a common target
impedance of 50 Ω
PIMPedance: normalize to the individual port reference impe-
dances
