section to guide you through some possible solutions. Each heading
lists a problem you may encounter, along with some possible solutions.
Error messages which may appear on the logic analyzer are listed

Target Board Will
Not Bootup
If the target board will not bootup after connecting the preprocessor
interface, the microprocessor or the preprocessor interface may not be
installed properly, or they may not be making electrical contact.
•
Verify that the microprocessor and the preprocessor interface
are properly rotated and aligned.
•
Verify that the microprocessor and the preprocessor interface
are securely inserted into their respective sockets.
•
Verify that the logic analyzer cables are in the proper sockets of
the preprocessor interface and firmly inserted.
•
Reduce the number of extender sockets (see also "Capacitive
Loading").
"Slow or Missing
Clock"
This error message might occur if the logic analyzer cards are not
firmly seated in the HP 16500A/B or HP 16501A frame. Ensure that
the cards are firmly seated.
This error might also occur if the target system is not running properly.
Ensure that the target system is on and operating properly.
If the error message persists, check the that the logic analyzer pods are
connected to the proper connectors, as listed in table 1-1.
For HP 1650A and HP 16510A Logic Analyzers, check the
preprocessor interface power fuse in the logic analyzer.
