Getting Started
This
section
will
teach
you the
basics of
operating the
4339B in
GPIB remote
mode (from
now
on
referred
to
as
remote). This
includes reading
the GPIB
address,
sending commands
to the
4339B
,
and
retrieving
data from
the 4339B
.
Input/Output
Statements
The
statements used
to operate
the 4339B
in
remote
depend
on
the
computer
and
the
programming
language being
used.
In
particular
,
you
need
to
know
the
statements
the
language
uses
to input
and
output
information.
The
input
statements
for
the
HP
9000
series
200
or
300
B
ASIC language
are:
ENTER
or TRANSFER
The
output
statement
is:
OUTPUT
Read
your
computer
manuals
to
nd
out
which
statements
you
need
to
use
.
Reading
the
GPIB
Address
Before
you
can
operate the
4339B in
remote,
you need
to
know
its
GPIB
address
(factory
setting=17).
T
o
check
the
address
,
press
.
A
typical
display
is:
The
displayed
response
is
the
device
address
.
When
sending
a
remote
command,
you
append
this
address
to
the
GPIB
interface's
select
code
(normally
7).
F
or
example
,
if
the
select code
is
7
and
the
device
address
is
17,
the
appended
combination
is
717.
Every
device
on
the
GPIB
bus
must have
a unique
address.
You
can
assign
new
GPIB
addresses
.
Sending
a
Remote
Command
T
o
send
a
remote
command

the 4339B
, combine
the computer's
output statement
with
the
GPIB
select
code
,
the
device
address
, and
nally the
4339B command.
For
example
,
to
reset
the
4339B
,
send:
OUTPUT 717;"*RST"

Rmt annunciator( 9 ) turns ON. This means the 4339B is in the remote
mode
.
Returning to Local Mode
When you press a key on the 4339B's keyboard while operating in remote

Rmt annunciator) the 4339B
ignores all front panel inputs except the
key.To return the 4339B to the Local mode,
