 Y <– S11, Y <– S12, Y <– S21, Y <– S22 select the converted admittances of a 2-port DUT.
 More Admittances... opens a dialog to select converted admittances for more ports or mixed mode
measurements.
Y <– S11, Y <– S12, Y <– S21, Y <– S22
Select the 2-port converted admittance parameters. The parameters describe the admittances 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, respectively.
The analyzer also provides converted admittances for more drive ports or balanced port configurations;
see More Admittances.
Use the More Y-Parameters dialog to measure Y-parameters including the transfer parameters. Use
the Inverted Smith chart to obtain an alternative, graphical representation of the converted admittances in
a reflection measurement.
