Sequencing Special Functions Menu; Sequence Decision Making Menu; Decision Making Functions; Having A Sequence Jump To Itself - Agilent Technologies 8719D User Manual

The TTL OUT softkey provides access to the TIZ out menu. This menu allows you to choose
between the following output parameters of the 'ITL output signal:
n TTL OUT HfGH
. TTL OUT LOW
The TI'L output signals are sent to the sequencing BNC rear panel output.

Sequencing Special Functions Menu

This menu is accessed by pressing the SPECIAL FUNL"ffONS softkey in the Sequencing menu.

Sequence Decision Making Menu

This menu is accessed by pressing the DECfSfOM NAKINE softkey 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 caIl 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 softkey descriptions.

Decision Making Functions

Decision making functions jump to a softkey location, not to a spectic 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 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 below.
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 LfNIT TEST P&Z5 and IF LIEIT TEST FAIL
commands require you to enter the destination sequence. ~
