Chapter 5: Troubleshooting

To test the cables

11 Move the starting position to -3 ns.

12 Run Eye Finder and ensure that an eye is found for each bit.

13 Select OK to close the Eye Finder window.

14 Select OK to close the Analyzer Setup window.

15 Switch to the Listing window and run the logic analyzer.

16 Examine the listing. If the listing shows that the data alternates between

0 AAAA and 1 5555 (or AAAA and 5555 if the pod does not have a clock

bit), then the probe and cable pass the test.

If the listing does not look similar to the figure, then there is a possible problem

with the cable or probe tip assembly. Causes for cable test failures include:

• open channel.

• channel shorted to a neighboring channel.

• channel shorted to either ground or a supply voltage.

17 Perform the test on all remaining pods, always using CLK 1 to clock in the

data.
