Chapter 5: Troubleshooting

b On the logic analyzer, select Run. Note the lower two bytes now

displays two decrementing counters, the upper two bytes displays two

incrementing counters.

If the error in the test data remains the same two bytes as the previous run (that

is, the error follows the cable) then the cable is suspect.

If the error is now in the opposite two bytes (that is, the error follows the E5378A

probe adapter) the probe adapter is suspect.
