Data Acquisition and Stimulus
State/Timing Modules
Eye Finder
Agilent’s eye finder examines the
signals coming from the circuit under
test and automatically adjusts the
logic analyzer’s setup and hold
window on each channel. Eye finder,
combined with 100 ps adjustment
resolution (10 ps on 16760A) on
Agilent’s logic analyzer modules,
yields the highest confidence in
accurate state measurements on
high-speed buses.
It takes less than a minute to run
eye finder. No special setup or
additional equipment is required.
You only need to run eye finder
once, when the logic analyzer is set
up and connected to the target.
Figure 4.4. The eye finder display.
Gray shading indicates
regions where
transitions are detected.
Blue bars indicate
the sampling point
selected by eye finder.
The eye finder display shows:
• Regions of transitions that were
discovered on all channels
selected
• The sampling point selected by eye
finder
If you want to select a different
sample point on any individual
channel, just drag and drop the blue
"sample" bar at the desired point.
Times in the eye finder display are
referenced to the incoming clock
transitions. The center of the display
(labeled "0 ns") corresponds to the
clock transitions.
