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 600 Mb/s mode.)
1 Using the mouse, drag the sample position (blue line) of a 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.
2 Repeat the above step for all remaining stray channels.
3 Select the Run button in the Eye Finder window. Eye Finder will
recalculate the new sample positions based on the sample position
changes. The following example shows all sampling positions aligned and
in the correct eye.
