Figure 2-44: JNEye Channel Setting with Link Design and Channel List
An S-parameter channel component such as a connector, cable, or backplane can be described by the
following parameters or information:
• ID—Sequence or location of the channel component. The top channel is connected to the transmitter
and the bottom channel is connected to the receiver.
Note: Embedded package models (such as Package models for Altera devices and PCI Express Gen3
devices) are not shown in the channel list or Link Designer.
• Channel Name—An S-parameter file that describes the channel component. The S-parameter can be
4-port, 8-port, 12-port, 16-port, and so forth. When your cursor hovers on a channel list, a tooltip
shows the S-parameter file location. This information is useful if you share JNEye configuration files.
• Type—Specify the type of channel characteristics to be used in the link simulation. The type of channel
characteristics can be insertion loss (Loss), far-end crosstalk (FEXT), or near-end crosstalk (NEXT).
You can change the channel (or channel type) by selecting the channel from the Link Designer using
the Channel Wizard.
• Port Configuration—Depending on the S-parameter measurement condition, the port configuration
can be one of the following types. Use the Channel Wizard to change the port configuration of an
S-parameter.
