Chapter 3: Testing Logic Analyzer Performance
Configure the Logic Analysis System
Adjust the sample positions using Eye Finder
1 Select the
Sample Positions
button. The Eye Finder window will appear.
2 In the “Buses/Signals” section of the Eye Finder window, ensure that the
check box next to “My Bus 1” is checked.
3 Select the plus sign to expand bus “My Bus 1”.
Align the blue bars vertically
The first time you run Eye Finder, the blue bars will already be vertically
aligned (as shown above). In this case you can skip to the next section
(“Run Eye Finder”).
After running Eye Finder, the blue bars will not be vertically aligned
because an independent sample position will be determined for each
channel.
4 If the blue bars in the Eye Finder display are not vertically aligned, grab
the right-most blue bar in the “My Bus 1” row with the mouse pointer and
move it all the way to the left. Release the mouse button. This will
vertically align all of the blue bars.
5 Using the mouse pointer, grab the top blue bar for “My Bus 1” and move it
to the recommended starting position of 300 ps. All of the blue bars below
will follow.
