Most
of the
HP-IB addresses
are set
at
the
factory
and
need
not
be
modied
for
normal
system
operation.
The standard
factory-set
addresses
for
instruments
that
may
be
part
of
the
system
are
as follows:
Instrument
HP-IB
Address
(decimal)
Analyzer
16
Plotter
05
Printer 01
External
Disk
Drive
00
Controller
21
Power
Meter 13
The address
displayed in
this menu
for
each
peripheral
device
must
match
the
address
set
on
the device
itself. The
analyzer
does
not
have
an
HP-IB
switch:
its
address
is
set
only
from
the
front
panel.
These
addresses
are
stored
in
non-volatile
memory
and
are not
aected by
preset or
by
cycling
the
power
.

The GPIO Mode
The GPIO mode turns the parallel
port into a \general purpose input/output" port.
In this mode the port can be
connected to test xtures
, power supplies
, and other peripheral
equipment that might be used to interact with
the analyzer during measurements
. This mode is
exclusively used in test sequencing.
