Trigger Sequence Specification - HP 1660CS-Series User Manual

Trigger sequence specification

See the following figure, which shows a sequence specification with four
levels. To define the trigger sequence, you specify sequence-advance,
sequence-else, storage, and trigger-on specifications.
Each level except the last has two branch conditions, the sequence-advance
and sequence-else specification. The storage specification indicates whether
data should be stored or not while the logic analyzer is at that sequence level.
(The trigger-on specification is a special sequence-advance specification that
is described in the section "Trigger On Specification.")
Sequence-else specifications
can branch to the same state
to a previous state
or a later state.
State analyzer sequence with four states
Sequence-advance specification The sequence-advance branch,
sometimes called the "if" branch or primary branch, always branches to
the next level. You can specify the following kinds of sequence-advance
specifications:
Find (or Then find) "<TERM>" <OCCURS> time
Find (or Then find) "<TERM>" <TIME PERIOD>
If the <TERM> is found <OCCURS> number of times or the <TERM>
remains stable for <TIME PERIOD>, the analyzer advances to the next
sequence level.

Trigger sequence specification
Sequence-advance
specifications always
branch to the next state.
Each state can have a
unique storage specification.
