Troubleshooting the Logic Analyzer

Analysis Probe Problems

This section lists problems that you might encounter when using an

analysis probe. If the solutions suggested here do not correct the

problem, you may have a defective analysis probe. Refer to the User's

Guide for your analysis probe for test procedures. Contact your local

Agilent Technologies Sales Office if you need further assistance.

Target system will not boot up

If the target system will not boot up after connecting the analysis

probe, the microprocessor or the analysis probe may not be installed

properly, or they may not be making electrical contact.

❏ Ensure that you are following the correct power-on sequence for the

analysis probe and target system.

1. Power up the analyzer and analysis probe.

2. Power up the target system.

If you power up the target system before you power up the analysis

probe, interface circuitry in the analysis probe may latch up,

preventing proper target system operation.

❏ Verify that the microprocessor and the analysis probe are properly rotated

and aligned, so that the index pin on the microprocessor (such as pin 1 or

A1) matches the index pin on the analysis probe.

❏ Verify that the microprocessor and the analysis probe are securely inserted

into their respective sockets.

❏ Verify that the logic analyzer cables are in the proper sockets of the

analysis probe and are firmly inserted.

❏ Reduce the number of extender sockets.
