Setting Pattern Durations and Occurrence Counts
(Timing Only)
When a bit pattern is found during a trigger sequence, you can
influence when the term actually becomes "true" by assigning a time
duration or an occurrence count.
The (>/</occurs) control may not be directly accessible if you are
editing a trigger function. To reveal it, break down (see page 88) the
function and then follow these instructions.
To Set a Pattern Duration
1. Select the (>/</occurs) option button and choose an option.
2. Set the duration or the number of occurrences.
When a greater-than or less-than duration is assigned, the secondary
branch (Else on) is not available.
When greater-than (>) is used, the analyzer continues sequence level
evaluation only after the resource term has been true for greater than
or equal to the amount of duration specified.
When less-than (<) is used, the analyzer continues sequence level
evaluation only after the resource term has been true for less than or
equal to the amount of duration specified. For each less-than
assignment, four internal sequence levels (see page 89) are used.
When occurs is selected, you can set an occurrence count. Use the
occurrence counter to delay the trigger sequence evaluation until a
resource term has occurred in a designated number of samples. These
samples may be interrupted by other values -- they do not need to be
consecutive.
Using Occurrence Counters
Use the occurrence counter to delay the trigger sequence evaluation
until a resource term has occurred in a designated number of samples.
