Trigger on Any Glitch

Qualifying Patterns

Less Than Duration

The trigger occurs when the specified pattern is present on the
probe signals for greater than 20 ns but less than the specified time
duration. Durations from 40ns to 10 ms in 10 ns increments can be
selected.
The command
trigger on less_than 60 nsec_of XBITS .2 =0
<RETURN>
sets the analyzer to trigger a trace if probe bit 2 is logically false for
less than 60 nanoseconds and more than 20 nanoseconds.
This type of trigger condition can only occur in the glitch capture
mode. In order for this trigger condition to become true, a glitch
must be found on the specified signals.
The command
trigger on any_glitch
sets the analyzer to only trigger if a glitch is found on any signal.
When you specify this "trigger on" option, the trigger is further
qualified by a selected change in another signal or set of signals.
The change can be a "positive_edge", a "negative_edge", or any edge
condition ("positive_or_negative_edge") on a specific bit or bits.
In glitch capture mode, the qualifiers are glitches on one or more
signals.
This option is useful as a means to locate the effects of an
occasional event such as a reset or interrupt.
The command
trigger on anything qualified_with
positive_edge XBITS .10 or_on positive_edge
XBITS .2 <RETURN>
sets the analyzer to trigger a trace on any activity after a positive
edge is detected on probe signal 10 or probe signal 2.
<RETURN>
