Out Menu
The provides access to the out menu. This menu allows you to choose
between the following output parameters of the output signal:
n
. OUT LOW
HIGH PULSE
SWEEP LOU PULSE
The output signals are sent to the sequencing BNC rear panel output.
Sequencing Special Functions Menu
This menu is accessed by pressing the SPECIAL in the Sequencing menu.
Sequence Decision Making Menu
This menu is accessed by pressing the in the Sequencing Special
Functions menu.
Decision making functions are explained in more detail below. These functions check a
condition and jump to a specified sequence if the condition is true. The sequence called must
be in memory. A sequence is a one-way jump. A sequence can jump to itself, or to any of
the other five sequences currently in memory. Use of these features is explained under the
specific descriptions.
Decision Making Functions
Decision making functions jump to a location, not to a sequence
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 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 in
conjunction with loop counter commands. See the loop counter description below.
input decision making
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” earlier in this section.
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 IF and IF TEST
commands require you to enter the destination sequence.
