Parameters:

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

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

See "Renormalization of S-parameters" on page 244.
