DESCRIPTION
The
Laser
Measurement System c
an
be
used
with
the I-Iewlen-Packard
Int
erface
Bus
(HP-I Bl. HP-
IB
is Hewlelt-Packard's implementation
of
IEEE
Standard 468-1978, "St<lndard Digital
Interface
for
Programmable Instrumentati
on"
.
HP
-IB capability gives you
an
easy
way to send
your
measurement data
10
a recording device; it al
so
enables more-automated applications, since it
allows the Measurement Display unit's functions
to
be
complete
ly controlled
from
an
external
c
ontro
ller.
An
HP-IB compatible device
is
used in an HP-IB system in
one
or
more
of
the
followin~
ways
•
As
a
LISTENER,
a device must be capable
of
acceptir
'8
data
from
the interface.
Examp
l
es
of
lis
teners
are
primers and plotters.
The Measurement Display
unit
has
limited
listener capability.
•
As
a
TALKER,
a device
mu
st be capable
of
outputting
data
to
the interfac
e.
Examples
of Talkers are voltmeters and tape readers.
The Measurement Display
unit
has
full talker capability.
•
As
a CONTROLLER, a device must be capablc
of
specifying the Talker and
listener
(
s)
of
a data transfer (
including
itself).
The Measurement Display
unit
has
no
c
ontroller
capab
il
ity.
The two major categories
of
HP
-
IB
sy
stems are
tho
se
with
, and those
without
, a "
controller"
.
Each
type
of
system
is
desc
rib
ed separately below.
A typical example
of
an
HP-IB
sy
stem wi
thout
a
controller
is s
imply
connecting
the
La
s
er
Measurement System to a suitable Printer. A typical example
of
a HP-IB system
with
a
controller
is
one
in which the
Laser
Measurement
Sy
s
tem
is
connec
ted
to
an
HP
Personal Calculat
or
that has
been sct
up
to act as a c
ontroller
