Analysis Probe Problems
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 pro be.
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.
