To re-align a stray channel
If the blue bar for a particular bit does not appear in its eye near the
recommended starting position, then do the following steps to realign the
sampling position of the stray channel.
In the following example, the sampling position of one channel (My Bus 1
[2]) must be realigned with the sampling position of the other channels.
(The following example shows the analyzer in the optional 500 Mb/s mode.
That is why the eyes are closer together.)
8 Using the mouse, drag the sample position (blue bar) of the stray channel
(channel “My Bus 1 [2]” in the above example) so that it is in the same eye
as the other channels. The Suggested Position from Eye Finder (green
triangle) will also move to the new eye. Repeat the above step for all
remaining stray channels.
9 Select the Run button in the Eye Finder window again.
The following example shows all sampling positions aligned and in the
correct eye.
