INTRODUCTION
This
Operation
Manual
is
suPplied
with
the
8756A
Operating
and
Service
Manual
as
a
reference
document
for
the
Instrument
Operator.
It
contains
a
1escriotion
of
the
instrument,
specifi~ations,
and
preparation
for
use,
as
well
as
information
on
using
the
8756A
in
both
manual
and
automatic
test
applications,
and
shoul~
be
kept
with
the
8756A.
The
convenience
and
accuracy
of
the
8756A
Scalar
Network
Analyzer
make
it
well
suited
for
a
variety
of
bench
top
and
automatic
(HP-IB)
test
eauioment
applications,
which
may
be
tailored
to
your
individual
needs.
In
OPERATING INFORMATION
you
will
find
the
information
needed
to
operate
the
8756A
in
either
the
local
or
remote
mode.
A
thorough
understanding
of
this
section
will
help
to
eliminate
a
multitude
of
operator
errors,
and
should
be
the
first
stop
for
the
operator
who
is
not
already
hiahly
skilled
in
the
operation
of
the
8756A.
Following
the
OPERATING INFORMATION,
you
will
find
Operatinq

and
Programming
Notes.

focuses
on
teaching
you
how
to
remotelv
program
your
instrument
with
a
specific

It
is
meant
to
be
an

remote
capabilities,
HP-IB,
and
use
of
the

INSTALLATION
2-1.
INTRODUCTION
2-2.
This
section provides installation instruc-
tions
for
the
Model
8756A
Scalar
Network
Analyzer
and
its accessories.
This
section also
includes information
about
initial inspection,
damage
claims,
preparation
for using the instru-
ment, packaging, storage,
and
shipment
2-3.
INITIAL INSPECTION
2-4.
Inspect
the
shipping
container
for
damage.
If
the
shipping
container
or
cushioning
material is
damaged
it
should
be kept until the
contents
of
the
shipment
have
been
checked for
completeness
and
the
instrument
has
been
checked mechanically
and
electrically.
The
con-
tents
of
the
shipment
should
be
as shown
in
Figure
1-1.
Procedures for checking electrical
performance are given in Section
IV.
If
the
instrument
does
not
pass the electrical perfor-
mance
tests, refer to the adjustments
in
Section
V
of
this manual.
If
a circuit
malfunction
is sus-
pected, refer to troubleshooting information
in
Section VIII.
If
the
instrument
does
not
pass the
above electrical tests,
or
if
the
shipment
contents
are
incomplete,
or
if
there
is
mechanical
damage
or
defect, notify the nearest Hewlett-
Packard
office.
If
the
shipping
container
is
damaged,
or
the
cushioning
material shows
signs
of
stress, notify the carrier as well as the
Hewlett-Packard
office.
Keep
the
shipping
materials for carrier's inspection.
The
HP
office
will arrange for
repair
or
replacement without
waiting for claim
settlement
2-5.

is
equipped
with a
three-wire
power
cable.
When
connected
to
an
approptiate
power
line outlet. this
cable
grounds
the
instrument

instruments.
The

Part
Num-
bers for
the

are
part
numbers
for
the
2-2
complete
power
cables.
The
type
of
power
cable/
plug
shipped
with
the
instrument
depends
upon
the
country
of
destination.
WARNING
I
Before
switching
on
this
instru-
ment,
be
sure
that
only
the
specified
power
cable is used.
The
instrument
is
provided
with
a
three-wire
power
cord
which
grounds
the
instrument
cabinet.
This
power
cord should only be
inserted in a
socket
outlet
provided
with
a
protective
earth
contact.
This
protective
action should
not
be
negated
by
the
use
of
an exten-
sion cord
(power
cable)
without
a
protective
conductor
(ground).
Grounding
one
conductor
of
a
two-
conductor
outlet
is
not
sufficient
protection.

The
offset
pin
of
the
three-prong
connec-
tor
is
the
grounding
pin.
When
operating
the
8756A from a two-contact outlet,
the
protective
grounding
feature
may
be
preserved by using a
three-prong to two-prong
adapter
(USA connec-
tors only,
HP
Part
Number
1251-0048)
and
con-
necting
the
green
wire
of
the
adapter
to

2-13.
HP-IB Address Selection
2-14.
When
the 8756A is used
under
remote
control with
the
HP-
IB, the controller
on
the
bus
refers to
the
8756A by
an
HP-IB
"address".
The
8756A is preset
in
firmware to address
16,
and
is differentiated from
any
other
instrument
on
the
bus
by this address.
The
HP-IB
address
may
be
modified
by
a
front
panel
SHIFT
function.
2-15. Twenty-nine different address codes are
available (I to
29).
The
8756A is
shipped
from
the factory preset to address
16.
In
all
standard
8756A instruments,
the
HP-IB
address will be
read
by the processor from firmware
upon
ini-
tial power
on
only. This
HP-IB
address will
remain
in effect until the address is
changed
by
resetting
through
the
front
panel
[SHIFn
[LOCAL] function.
The
HP-IB
address
may
be
read directly from
the
front
panel
by pressing
[SHIFn
[LOCAL].
The
current
HP-IB address
is
then
displayed
on
the
CRT.
If
the
HP-IB
address
must
be
changed
from
that
which
is
dis-
played,
enter
the
new
address
and
press
[ENn
to
terminate
the entry.
The
display
should
now
show
the
new
HP-
IB address.
This
address is
not affected by
turning
the
LINE
switch off,
or
by a
PRESET
command.
2-16. HP-IB address labels are available by
ordering
HP
Part
Number
7120-6853 (each).
(See
Figure
2-2).
These
labels
allow
easy
reference to the HP-IB address
of
each system
component.
2-17.
Mating
Connectors
2-18. All
of
the externally
mounted
connectors
of
the 8756A are listed in

HP Interface Bus and

System
Interface Connectors and Cables
2-20.
The
HP
Interface Bus Interface
Connec-
tor is located
on
the
rear
panel
of
the 8756A.
A10J2 allows the 8756A to
be
connected
to a
controller via HP-IB, with
or
without
additional
instruments.
An
illustration
of
pin
configuration
and
signals
on
the
HP
Interface Bus
connector
is given
in
Figure
2-3.
2-21.
The
8756 System Interface
Connector
is
located
on
the rear
panel
of
the 8756A. A10Jl
allows the 8756A to
be
connected
to the 8350B
or
8340A swept microwave sources,
and/
or
the
7470A
or
9872C digital plotters.
The
8756A itself
controls the 8756 System Interface,
and
there
must
be
no
other
controllers
attached
to this
connector
(see Figure 2-3).
2-22. All
instruments
on
the
HP
Interface Bus
or
the 8756 System Interface Bus are intercon-
nected by
HP-
IB Interface Cables. A list
of
the
available HP-IB Cables
and
their
part
numbers
is
given
in
Figure
2-4.
As
many
as
15
instruments may be
connected
in
parallel
on
the
HP
Interface Bus
or
the 8756 System Interface.
To achieve design
performance
on
the bus, pro-
per
voltage levels
and
timing relationships
must
be maintained.
If
the system cable is too long
or
if
the
accumulated
cable
length
between
instruments
is
too long, the
data
and
control
lines
cannot
be driven properly
and
the system
may fail to perform. Therefore. the following
restrictions
must
be observed:
a.
With two instruments in a system, the cable
length must
not
exceed 4 metres (12 feet).
