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.
