MMEMory:STORe:TRACe:OPTion:TRIM <Boolean>
This command defines whitespace insertion during Touchstone file export.
If set to ON, whitespace at the beginning of each line is removed.
Parameters:
<Boolean>
Manual operation: See "Trim Leading Whitespace" on page 760
MMEMory:STORe:TRACe:PORTs
<Channel>, <TouchstoneFile>, <Format>[,
<ModeImpedance>, <Port>[, <Port>]...]
Generates an snpTouchstone file, where n is the number of specified ports.
If the specified physical ports comprise at least one balanced port and MMEMory:
STORe:TRACe:OPTion:BALanced is ON, the Touchstone file contains the full set of
mixed mode S-parameters. Otherwise it contains the full set of single-ended S-param-
eters. 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 158. Traces are created using the
CALCulate<Ch>:PARameter:SDEFine command.
Setting parameters:
<Channel> Channel number in the active recall set.
<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
See "Renormalization of S-parameters" on page 159.
