Selects the 2-port converted impedance parameters. The parameters describe the
impedances of a 2-port DUT, obtained in forward and reverse transmission and reflec-
tion measurements:
●
Z
11
is the input impedance at port 1 of a 2-port DUT that is terminated at port 2 with
the reference impedance Z
0
(matched-circuit impedance measured in a forward
reflection measurement).
●
Z
22
is the input impedance at port 2 of a 2-port DUT that is terminated at port 1 with
the reference impedance Z
0
(matched-circuit impedance measured in a reverse
reflection measurement).
●
Z
12
and Z
21
denote the forward and reverse converted transfer impedances,
respectively.
Use the Smith chart to obtain an alternative, graphical representation of the converted
impedances in a reflection measurement.
Tip: Use the "Y- Z-Params" tab to measure Z-parameters including the transfer param-
eters.
Remote command:
CALCulate<Ch>:PARameter:MEASure "<Trace_Name>", "Z-S11" |
"Z-S12" | "Z-S21" | "Z-S22"
Create new trace and select trace name and measurement parameter:
CALCulate<Ch>:PARameter:SDEFine "<Trace_Name>", "Z-S11" |
"Z-S12" | "Z-S21" | "Z-S22"
Balanced Ports...
Opens a dialog to configure the logical ports of the analyzer.
See Chapter 5.9.1.3, "Balanced Ports Dialog" , on page 440.
5.9.6 Y←Sij Tab
Selects converted admittances as measured quantities. The admittances are calcula-
ted from the measured S-parameters.
