Opens the Y-Parameter dialog to select arbitrary Y-parameters for different ports or mixed mode measurements. In analogy to the converted admittances, the Y-parameters are available for any combination of input and output ports.
Y-parameters can be used as an alternative to S-parameters (or Z-parameters) in order to completely characterize a linear n-port network.
Converted
impedances and Z-parameters
Opens a dialog to select 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 Balanced Port and Port Groups dialog 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 unbalance-balance 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.
The port configuration
is valid for all traces in the channel
The settings made in the Balanced and Measured Ports dialog are channel settings and therefore apply to all traces assigned to the channel (Balanced and Measured Ports is also accessible through Channel –Mode–Port Config...). Within a channel the analyzer measures either single-ended or mixed mode parameters. If a balanced test port configuration is selected the single-ended parameters assigned to the channel are converted into mixed mode parameters.
