Analyzer Problems
This section lists general problems that you might encounter while
using the analyzer.

Intermittent data errors

This problem is usually caused by poor connections, incorrect signal
levels, or marginal timing.
❏With the logic analyzer and all connected equipment turned off, remove
and reseat all cables and probes; ensure that there are no b ent pins on the
analysis probe or poor probe connections.
❏Adjust the threshold level of the data pod in the Format menu to match
the logic levels in the system under test.
❏Use an oscilloscope to check the signal integrity of the data lines.
Clock signals for the state analyzer must meet particular pulse shape
and timing requirements. Data inputs for the analyzer must meet pulse
shape and setup and hold time requirements.
See Also "Capacitive loading" in this section for information on other sources of
intermittent data errors.
