6.2.6 Y←Sij Tab
Selects converted admittances as measured quantities. The admittances are calcula-
ted from the measured S-parameters.
Background information
Refer to the following sections:
●
Chapter 5.3.4, "Admittance Parameters" , on page 124
●
Chapter 5.3.4.1, "Converted Admittances" , on page 124
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.

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.
