"Waiting for Trigger"

"Waiting for Trigger"
If a trigger pattern is specified, this message indicates that the specified
trigger pattern has not occurred. Verify that the triggering pattern is
correctly set.
When analyzing microprocessors that fetch only from long-word aligned
addresses, if the trigger condition is set to look for an opcode fetch at an
address not corresponding to a long-word boundary, the trigger will
never be found.
If a "don't care" trigger condition is set, this message indicates:
For an HP 16511B Logic Analyzer, only one of the two cards is receiving
its state clock. Refer to "Slow or Missing Clock."
For an HP 16510A/B Logic Analyzer, the pattern duration is probably set
to less than (<) instead of greater than (>). Since a "don't care" pattern is
always true, the "less than" condition is never satisfied. Set the trigger
correctly for the measurement that is desired.
