HP 54501A - Device Listening Syntax

Device
Listening
Syntax
The
listening
syntax
of
IEEE
488.2
is
designed
to
be
more
forgiving
than
the
talking
syntax.
This
allows
greater
flexibility
in
writing
programs,
as
well
as
allowing
them to
be
easier
to
read.
Upper/Lower Case Equivalence.
Upper
and
lower case letters
are
equivalent.
The
mnemonic
RANGE
has
the
same semantic
meaning
as
the
mnemonic
range.
<
white
space
>.
<
white
space
>
is
defined to
be
one
or
more
characters
from
the
ASCII
set
of
0
-
32
decimal,
excluding
10
decimal
(NL).
<
white
space
>
is
used
by
several instrument
listening
components
of
the
syntax.
It
is
usually
optional,
and
can
be
used
to
increase
the
readability
of
a
program.
