Using Test Sequencing
Decision Making Functions
Decision making functions jump to a softkey location, not to a specific sequence
title Limit test, loop counter, and do sequence commands jump to any sequence residing
in the specified sequence position (1 through 6). These commands do not jump to a specific
sequence title. Whatever sequence is in the selected softkey position, will run when these
commands are executed.
Having a sequence jump to itself A decision making command can jump to the
sequence it is in. When this occurs, the sequence starts over and all commands in the
sequence are repeated. This is used a great deal in conjunction with loop counter
commands. See the loop counter description that follows.
TTL input decision making TTL input from a peripheral connected to the parallel port
(in the GPIO mode) can be used in a decision making function. Refer to "The GPIO Mode"
on page 1-107.
Limit test decision making A sequence can jump to another sequence or start over
depending on the result of a limit test. When entered into a sequence, the
and commands require you to enter the
destination sequence.
Loop counter decision making The analyzer has a numeric register called a loop
counter. The value of this register can be set by a sequence, and it can be incriminated or
decremented each time a sequence repeats itself. The decision making commands
and jump to another sequence if the
stated condition is true. When entered into the sequence, these commands require you to
enter the destination sequence. Either command can jump to another sequence, or restart
the current sequence.
As explained in "Embedding the Value of the Loop Counter in a Title" on page 1-106, the
loop counter value can be appended to a title. This allows customized titles for data
printouts or for data files saved to disk.
