introduction
This
note
is
a
guide
to
the
basic
operation
of
the
59501A,
as
either
a
remote
power
supply
programmer
or
a
programmable
low
level
DC
voltage
source,
with
the
HP
85
computer.
Familiarity
with
the
HP
85
and
its
programming
language,
BASIC,
makes
the
examples
more
mean¬
ingful.
The
HP
85's
capabilities
are
best
described
in
the
manuals
listed
in
the
section
titled
Related
Documents.
To
acquaint
yourself
with
the
HP
85,
review
these
manuals
and
use
them
as
a
reference
as
you
gain
experience.
When
you
are
familiar
with
the
HP
85,
this
note
will
enable
you
to
quickly
write
pro¬
grams
that
control
the
59501A.

In
addition
to
the
modes
of
operation
described
in
this
note,
the
59501A,
and
HP
85
have
other
useful
capabilities.
The
materials
listed
below
contain
com¬
plete
documentation
for
all
of
these
capabilities.
They
can
be

For
operation
as
a
power
supply
programmer:
a.
Find
the
correct
wiring
diagram
below,
cor¬
responding
to
power
supply
model
number,
and
either
CV
or
CC
mode
of
operation.
(See
Table
1).
b.
Arrange
the
barrier
strip
jumpers
on
the
power
supply
as
illustrated
in
the
diagram.
c.
Remove
internal
jumpers
or
components
from
the
power
supply
if
diagram
requests.
d.
Wire
the
59501A
to
the
power
supply
as
il¬
lustrated.
e.
Set
range
switch
on
power
supply
if
applicable.
f.
Before
permanently
wiring
the
power
supply
to
the
59501A,
check
the
power
supply
operating
and
service
manual
for
proper
wiring
technique
and
external
components
which
may
be
needed
to
insure
ripple
and

Before
programming
a
59501A-power
supply
combination,
a
two-step
calibration
procedure
must
be
performed
to
match
the
particular

A
similar
calibration
is
necessary
when
the

The
59501A
is
an
HP-IB
instrument
capable
of
perfor¬
ming
a
LISTEN
function
on
the
interface
bus.
It
is
pro¬
grammed
by
a
data
word
comprised
of
four
digits.
The
first
digit
selects
the
range
and
the
following
three
digits
specify
the
desired
output
within
the
range,
in
terms
of
percentage
of
full
scale.
The
59501A
output
is
either
unipolar
or
bipolar,
depending
on
the
position
of
the
mode
switch
on
the
back
panel.

Program
Before
choosing
the
three
magnitude
digits,
the
range
digit
must
be
selected,
The
low
range
covers
0-9.99%
{0-0.999
volts),
and
the
high
range
0-99.97o
(0-9.99
volts).
For
an
output
between
1
and
9.99
volts,
the
high
range
must
be
used.
However,
an
output
of
less
than
1
volt
could
be
pro¬
grammed
with
either
range.
Using
only
the
high
range
makes
programming
slightly
simpler,
but
range
decoding
provides
for
better
resolution
in
the
low
end.
Figure
40
shows
a
method
of
implementing
range
decoding.

The

may
be

to
demonstrate
this
type

The
59501A
