for
use
in
program
messages
and
query
responses
.
The
4349B
accepts commands
and
parameters
in
various
formats
and
responds
to
a
particular
query
in a
predened
and
rigid
format.
Each
command
reference
contains
information
about
available
parameter types
for
the
individual
commands
.
<
numeric
value
>
is
used
in
both
common
commands
and
subsystem
commands
.
<

4349B
settings
programmed
with
a
numeric
parameter
can
assume
a
nite
number
of values
,
so
the
4349B
automatically
rounds
the
parameter
.
F
or
example
,
the 4349B
has programmable
line
frequencies
of
50
or
60
Hz
.
If
you
specied 50.1
,it
would
be
rounded
o
to
50
.
The
subsystem
commands
can
use
extended
numeric
parameters
.
Extended
numeric
parameters
accept
all
numeric
parameter
values
and
other
special
values,
for instance
,
MAXimum
,
MINimum
or
UP
,
DOWN
.
The
special values
available for
a command
are described
in
the
each
command's
reference
description.
Query
response
to
< numeric

is
always a
numeric value
.
<
Boolean

represents
a
single binary
condition
that
is
either
ON

In
a
program
message
and
query
response
<
sensor
function
>
and
<
data
handle
>
are
string
parameters
which
contain
ASCII
characters
.A
string
must
begin
with
a
single
quote(ASCII
39
decimal)
or
a
double
quote
(ASCII
34 decimal)
and
end
with
the
same
character
.
The
quote
to
mark
the
beginning
and
end
of
the
string
is
called
the
delimiter
.
Y
ou
can
include
the
delimiter as
part of
the string
by
typing
it
twice
without
any
characters
in
between.
Example
of
<
sensor
function
>
"CURR"
,
10
OUTPUT
@Meter;":FUNC
'CURR'"
using
single
quote
20 OUTPUT
@Meter;":FUNC ""CURR"""
using double
quote
Query response
is
the
string
between
the
double
quote
delimiters
.
