Trigger String
The
trigger string
numeric data
is
a
string
of
Generator
commands
terminated with
an
EOR.
The
string
may
be
up
to 71
characters,
not including
the
EOR.
Commands
in
the string are
not
checked
for validity until the trigger string
is
executed with
the
trigger
command.
EOR
is
the
end
of record
character.
This character
is
selected
with the
terminator
mode command.
"TMO"
selects
the linefeed character.
"TMl"
selects
the carriage
return character.
The IEEE-488
interface signal
EOI
asserted
with
any
other
character
is
also
considered
an end
of record.
EOS
is
an end
of
string
character, use either
or
"»"•
x^--
(TioRT)

SUFFIX
SYNTAX
Suffixes are
always one
or
two
alpha-characters.
Certain
suffixes are
used
to scale
the
numeric
(the
same
as
the front panel
UNITS
keys).
Other
suffixes
mnemonically
designate
hardware
components.
The
five
types of
suffixes are
described
in
Table
2-11.

Command
Descriptions
The
following
paragraphs
describe the
remote
IEEE-488
Interface
operating
commands
that
are
not
accessible
from
the front
panel of
the
Generator.
IEEE-488
Interface
commands
that
are accessible
from
the front
panel
of the
Generator
are described
earlier in this
section
(Local
and
Remote
Operation).

BINARY
LEARN
COMMANDS
Front panel
setups
are stored
in
the
memory
of the
Generator
in
a packed binary format.
The
binary learn
commands
are
used
to transfer
this
binary data
between an IEEE-488
controller
and
the
Generator. These
commands
allow the operator
to
minimize
the
amount
of
programming
commands
needed
to
program
the
entire
instrument
state.
The
binary
learn
commands
are:
"LM"
Learn
Memory
"LI" Learn
Interface
The
syntax
for
the
Learn
Memory
("LM")
command
is
as
follows:
"LM" Memory
Location
Code
The
Generator responds
to
the
"LM"command
with
a
string
of 66
ASCII
characters
followed
by an
<EOR)
(end of record
character).
This
string
represents
the front
panel
settings
(in
a
packed
binary format)
that
were
stored
in
the
memory
location
specified.
