Converted admittance parameters are expressed as Y <-
<out>< in>
, where <out> and <in>
denote the output and input port numbers of the DUT.
Remote command:
"<Trace_Name>", "Y-S11" |
"Y-S12" ...
Create new trace and select trace name and measurement parameter:
"<Trace_Name>", "Y-S11" | "Y-S22"
| ...
Y<-S11 / Y<-S12 / Y<-S21 / Y<-S22
Selects the 2-port converted admittance parameters. The parameters describe the admit-
tances of a 2-port DUT, obtained in forward and reverse transmission and reflection
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, respec-
tively.
Tip:
Use the "Y- Z-Params" tab to measure Y-parameters including the transfer param-
eters. Use the inverted Smith chart to obtain an alternative, graphical representation of
the converted admittances in a reflection measurement.
Remote command:
"<Trace_Name>", "Y-S11" | "Y-S12"
| "Y-S21" | "Y-S22"
Create new trace and select trace name and measurement parameter:
"<Trace_Name>", "Y-S11" | "Y-S12"
| "Y-S21" | "Y-S22"
Balanced Ports...
Opens a dialog to define a balanced port configuration.

Meas > Y-Z-Params
Selects Y and Z-parameters as measured quantities. Both the Y-parameters and the Z-
parameters can be used as an alternative to S-parameters in order to completely char-
acterize a linear n-port network.
