Y←S<out><in> selector
Selects a
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.
Remote command:
CALCulate<Ch>:PARameter:MEASure
"<Trace_Name>", "Y-S11" |
"Y-S12" ...
CALCulate<Ch>:PARameter:SDEFine
"<Trace_Name>", "Y-S11" |
"Y-S22" | ...
Y←S<out><in> softkeys
Selects the 2-port
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.
Tip:
Use the "Y- Z-Params" tab to measure Y-parameters including the transfer param-
eters.
