HP 54501A - Programming Syntax; Talking to the Instrument

Programming
Syntax
Talking
to
the
Instrument
In
general,
computers
acting
as
controllers
communicate
with
the
instrument
by passing
messages
over
a
remote
interface
using
the
I/O
statements
provided
in
the
instruction set
of
the controller's
host
language.
Hence,
the HPSL
1.0 messages
for
programming
the
HP
54501A,
described in
this
manual,
will
normally
appear
as
ASCII
character
strings
imbedded
inside
the
I/O
statements
of
your
controller's
program.
For
example, the
HP
9000
Series
200/300
BASIC
and
PASCAL
language
systems
use
the OUTPUT
statement
for
sending
program
messages
to
the
HP 54501A,
and
the
ENTER
statement
for
receiving
response
messages
from
the
HP
54501A.
Messages
are
placed
on
the
bus
using
an output
command
and
passing
the
device
address,
program
message,
and
terminator.
Passing
the
device
address
ensures
that
the
program
message
is
sent
to
the
correct
interface
and
instrument.
The
following
command
turns
the
command
headers
on:
OUTPUT
<
device address
>
;":SYSTEM:HEADER
ON"
<
terminator
>
<
device address
>
represents
the address
of
the device
being
programmed.
Note
The
programming
examples
in this
manual
are
written
in
HP
Basic
4.0
for
an
HP
9000
Series
200/300
Controller.
