No activity on activity indicators
Check for loose cables, board connections, and preprocessor interface
connections.
Check for bent or damaged pins on the preprocessor probe.
No trace list display
If there is no trace list display, it may be that your trigger specification is not
correct for the data you want to capture, or that the trace memory is only
partially filled.
Check your trigger sequencer specification to ensure that it will capture
the events of interest.
Try stopping the analyzer; if the trace list is partially filled, this should
display the contents of trace memory.
Analyzer won’t power up
If logic analyzer power is cycled when the logic analyzer is connected to a
target system or software probe that remains powered up, the logic analyzer
may not be able to power up. Some logic analyzers are inhibited from
powering up when they are connected to a target system or software probe
that is already powered up.
Disconnect all logic analyzer cabling from the preprocessor. This will
allow the logic analyzer to power up. Reconnect logic analyzer cabling
after power up.
