Y←S<out><in> selector
Selects a converted admittance parameter as a measured quantity for the active trace.
For an n-port vector network analyzer, the pull-down list provides the full set of n
2
admittance parameters.
Converted admittance parameters are expressed as Y←S
<out>< in>
, where <out> and
<in> denote the output and input port numbers of the DUT.
Note: For a unidirectional R&S ZND (see Chapter 4.1.4.3, "R&S ZND: unidirectional
vs. bidirectional operation" , on page 80) the reverse direction cannot be measured.
Hence Y←S
12
, Y←S
22
are not available.
Remote command:

"Y-S22" | ...
Y←S<out><in> softkeys
Selects the 2-port converted admittance parameters. The parameters describe the
admittances of a 2-port DUT, obtained in forward and reverse transmission and reflec-
tion measurements:
●
Y
11
is the input admittance at port 1 of a 2-port DUT that is terminated at port 2 with
the reference impedance Z
0
(matched-circuit admittance measured in a forward
reflection measurement).
●
Y
22
is the input admittance at port 2 of a 2-port DUT that is terminated at port 1 with
the reference impedance Z
0
(matched-circuit admittance measured in a reverse
reflection measurement).
●
Y
12
and Y
21
denote the forward and reverse converted transfer admittances,
respectively.
Use the Smith chart to obtain an alternative, graphical representation of the converted
impedances in a reflection measurement.
Note: For a unidirectional R&S ZND (see Chapter 4.1.4.3, "R&S ZND: unidirectional
vs. bidirectional operation" , on page 80) the reverse direction cannot be measured.
Hence Y
12
and Y
22
are not available.
Tip: For a bidirectional R&S ZND, you can use the "Y- Z-Params" tab to measure Y-
parameters including the transfer parameters.
Remote command:
CALCulate<Ch>:PARameter:MEASure "<Trace_Name>", "Y-S11" |
"Y-S12" | "Y-S21" | "Y-S22"
CALCulate<Ch>:PARameter:SDEFine "<Trace_Name>", "Y-S11" |
"Y-S12" | "Y-S21" | "Y-S22"
Model
In case a transmission parameter is selected, you can choose between a series
(default), and a parallel admittance calculation.
