HP 3468A - Page 50

Writi Programs (Cont'd)
The second line sets up a string of commands which is sent to the 3468A by the
OUTA command of line 03. Line 04 is used to input the measured ac voltage to
the calculator; line O5 ends the program.
Programs such as this are very easy to write if the 3468A is the only device in
the loop with the calculator. Often times, however, you'll want to include a
printer/plotter and a mass storage cassette drive along with the 3468A. In such
instances, the calculator interface module should be initialized and the 3468A
selected and put in the remote mode.
Initialization
The
following
program
locates
the
3468A
in
the
loop
(finds
its
address),
selects
it
to
receive
information,
and
puts
the
3468A
into
the
REMOTE
mode.
This
program
should
be
executed
before
any
other
command
or
program
is
executed.
This
in-
itialization
program
need
only
be
executed
once
unless
a
device
is
turned
off
or
the
loop
is
broken
to
insert
or
remove
a
device.
The
82160A
HP-IL
module
must
be inserted
in the calculator
before
entering
the program.

The initialization program has now been entered. If you have not yet connected
your 3468A into the loop, do so now. Remember to turn your calculator off
before connecting the 3468A. The initialization program will not be lost in the
calculator with power turned off.
