In presence of balanced ports, standard S-parameters are defined in the form
S<m_out><m_in><out><in>, where output mode <m_out> and input mode <m_in> can
be one of:
●
d (differential, balanced)
●
c (common, balanced)
●
s (single-ended, unbalanced)
It is also possible to display "raw" single-ended S-parameters within the same channel:
after setting the S-Parameter type to "S" any pair of (used) physical ports can be
selected.
Remote command:
CALCulate<Ch>:PARameter:MEASure
CALCulate<Ch>:PARameter:MEASure:SENDed
CALCulate<Ch>:PARameter:SDEFine
CALCulate<Ch>:PARameter:SDEFine:SENDed
S<out><in>
Selects one of the four elements of the standard 2-port S-parameters as a measured
quantity for the active trace.
Remote command:
CALCulate<Ch>:PARameter:MEASure "<Trace_Name>", "S11" | "S12" |
"S21" | "S22"
CALCulate<Ch>:PARameter:SDEFine "<Trace_Name>", "S11" | "S12" |
"S21" | "S22"
All S-Params
Creates 4 diagrams and displays the full set of S-parameters, one in each diagram.
The diagrams are arranged as an (2 x 2) matrix.
Remote command:
CALCulate<Ch>:PARameter:SDEFine
CALCulate<Ch>:PARameter:DEFine:SGRoup
S-Param Wizard...
Opens a dialog that guides you through the setup of a standard multi-port S-parameter
measurement in a frequency sweep. See Chapter 10.7.1.2, "S-Parameter Wizard",
on page 396.
Balanced Ports...
Opens a dialog that allows you to enable/disable physical ports and to define logical
ports (balanced or unbalanced) in the active channel. See Chapter 10.7.1.3, "Balanced
Ports dialog", on page 398.
Note: If the "Fixture Simulator" is disabled for the related channel (see "Fixture Simula-
tor" on page 527), the "Balanced Ports..." button is inactive (grayed out).
10.7.1.2 S-Parameter Wizard
The "S-Parameter Wizard" guides you through the setup of a standard two-port S-
parameter measurement in a frequency sweep.
