the
trigger. Each
time
a
trigger command
or
a
group execute trigger inter-
face

is
received, the
Generator executes
the
string
of
commands. The

must
end with
a

More
details
about
the
commands
can be found
in
two
places.
Commands
that are available
from
the front
panel
are
described
earlier in this
section
(Local
and
Remote
Operation).
Those
commands
that are
only
available
from
the
IEEE-488
Interface are
described
in
the
Command
Descriptions paragraphs
later in this
section.
Table
2-7
is
an
index
for the
IEEE-488
Commands
used
in
Table
2-8.
This index
is
a
list
of
the
command
headers according
to
function.
Table
2-8
lists all
the
remote
commands
that are
recognized
by
the
Generator.
The
commands
are
listed
alphabetically
by
function.
The
following
three
examples
show
how
to
use
the
IEEE-488
bus and
how
to
use a variety of
controllers
to
program
the
Generator. In
the
first
example,
a
Fluke
1722A
Controller
is
used
to
program
the
Generator.
In the
second example,
two
Generators
are
configured
to
track
each
other
in
frequency. In
the third
example,
a
I722A
is
used
to
program
the
Generator with
the
frequency
step
up
controlled
by
the trigger
command.
