Y-Parameters
Opens the Y-Parameter dialog to select arbitrary short-circuit Y-parameters for different ports or mixed
mode measurements. In analogy to the matched-circuit admittances, the short-circuit Y-parameters are
available for any combination of input and output ports.
Short-circuit Y-parameters can be used as an alternative to S-parameters (or open-circuit Z-
parameters) in order to completely characterize a linear n-port network.
Y-Parameter
Opens a dialog to select short-circuit Y-parameters for multiport measurements (including the 2-port Y-
parameters) or mixed mode Y-parameters.
The notation for Y-parameters and the functionality of the Y-Parameter dialog is analogous to the
definition of S-parameters. The dialog provides the following settings:
•
Y-Parameter selects the type (left pull-down list) and the port number assignment (right pull-
down list) of the Y-parameter. Mixed mode parameters are only available if a balanced port
configuration is active. They are expressed as Y
<mout><min>
, where <mout> and <min> denote the
output and input port modes. The port numbers are assigned in the order Y
<out>< in>
, where
<out> and <in> denote the output (response) and input (stimulus) port numbers of the DUT.
•
Balanced and Measured Ports opens the dialog of the same name to define the properties of
the test ports. Single-ended (unbalanced) Y-parameters are assigned to the physical test ports
of the analyzer. Balanced Y-parameters are assigned to logical test ports. Selecting a balanced
port configuration with logical test ports means that the balance-unbalance conversion is
switched on and that the analyzer provides mixed mode parameters.

The graphics above the Balanced and Measured Ports button illustrates the current port
configuration.
