Eye Finder Advanced Settings Dialog.
Short Eye finder looks at 100,000 clock cycles on each channel
to determine the suggested sampling positions. This setting
requires frequent transitions on all channels.
Medium Eye finder looks at 500,000 clock cycles on each channel
to determine the suggested sampling positions. Use this for
channels that transition at a normal rate.
Long Eye finder looks at 2.5 million clock cycles on each
channel to determine the suggested sampling positions.
Use this setting if some channels have sporadic transitions.
Custom Lets you specify the number of clock cycles to sample on
each channel at each sampling position (each point in
time).
Accumulate
Results When selected, eye finder data is accumulated from run-
to-run. When unselected, eye finder data is erased before
each run.
Some things to consider when selecting among the eye finder
advanced settings are:
• Upper address bits that don't transition as frequently as lower address bits.
