HP 54501A - Program Header Options; Program Data

Program
Header
Options
Program
headers
can
be
sent
using
any
combination
of
uppercase
or
lowercase
ASCII
characters.
Instrument
responses,
however, are
always
returned
in
uppercase.
Both
program
command
and
query
headers
may
be
sent
in
either
longform (complete
spelling),
shortform
(abbreviated
spelling),
or
any
combination
of
longform
and
shortform.
Either
of
the
following
examples
turn
the
headers
on.
:SY?TEM:HEADERON
-longform
:SYCT:HEAD
ON
-
shortform
Programs
written in
longform
are
easily
read
and
are
almost
self-documenting.
The
shortform syntax
conserves
the
amount
of
controller
memory
needed for
program
storage
and
reduces
the
amount
of
I/O
activity.
Note
The
rules
for
shortform
syntax
are
shown
in
the
chapter
"Programming
and
Documentation
Conventions."
Program
Data
Program
data
is
used
to convey
a
variety
of
types
of
parameter
information
related to
the
command
header.
At
least
one
space must
separate
the
command
header
or query
header from
the
program
data.
<
program
mnemonic
> <
separator
>
<data>
<
terminator
>
When
a
program
mnemonic
or query
has
multiple
data
parameters
a
comma
separates
sequential
program
data.
<
program
mnemonic
> <
separator
> <
data
>,
<

<
terminator

For
example,
:TRIGGER:DELAY
TIME,1.23E-01
has
two
data
parameters:
TIME
and 1.23E-01.
