SAFETY SUMMARY
The following general safety precautions must be observed during all phases
of
operation, service,
and repair
of
this instrument. Failure
to
comply with these precautions
or
with specific warnings
elsewhere
In
this manual violates safety standards
of
design, manufacture, and intended use
of
the
instrument. Hewlett-Packard Company assumes
no liability for the customer's failure
to
comply
with these requirements.
GROUND
THE
INSTRUMENT.
To
minimize shock hazard, the instrument chassis and cabinet must
be
connected to an electrical
ground. The instrument
is
equipped with a three-conductor ac power cable. The power cable
must either
be
plugged into
an
approved three-contact electrical outlet or used with a three-contact
to two-contact adapter with the grounding wire (green) firmly connected to
an
electrical ground
(safety ground) at the power outlet. The power jack and mating plug of the power cable meet
International Electrotechnical Commission (IEC) safety standards.
DO
NOT
OPERATE IN AN EXPLOSIVE ATMOSPHERE.
Do
not operate the instrument
in
the presence of flammable gases or fumes. Operation of any
electrical instrument
in
such
an
environment constitutes a definite safety hazard.
KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers. Component replacement and internal
adjustments must
be
made
by
qualified maintenance personnel.
Do
not replace components with
power cable connected. Under certain conditions, dangerous voltages may exist even with the
power cable removed. To avoid injuries, always disconnect power and discharge circuits before
touching them.
DO
NOT
SERVICE OR ADJUST ALONE.
Do
not attempt internal service or adjustment unless another person, capable of rendering first aid
and resuscitation,
is
present.
USE
CAUTION
WHEN EXPOSING OR
HANDLING
THE
CRT.
Breakage of the Cathode-ray Tube (CRT) causes a high-velocity scattering of glass fragments (implosion).
To prevent CRT implosion, avoid rough handling or jarring of the instrument. Handling of the CRT shall
be
done only
by
qualified maintenance personnel using approved safety mask and gloves.
DO
NOT
SUBSTITUTE PARTS OR
MODIFY
INSTRUMENT.
Because of the danger of introducing additional hazards, do not install substitute parts or perform
any unauthorized modification to the instrument. Return the instrument to a Hewlett-Packard
Sales and Service Office for service and repair to ensure that safety features are maintained.
DANGEROUS PROCEDURE WARNINGS.
Warnings, such
as
the example below, precede potentially dangerous procedures throughout this
manual. Instructions contained
in
the warnings must
be
followed.
I WARNING I
Dangerous voltages, capable of causing death, are present
in
this instrument.
Use extreme caution when handling, testing, and adjusting.

This
manual
provides
operating
and
servicing
information
for
the
Hewlett-Packard
Model 1317 A
High
Speed
Graphic
Display
(figure

The
manual
is divided
into
eight
sections,
each
covering a specific
aspect
of
the
instrument.
All
schematics
are
located
at
the
rear
of
Section VIII.

This
section
contains
general
information
per-
taining
to
the
instrument.
Table

lists
the
abbre-
viations
used
throughout
this
manual,
except

are
listed
and
described
in
Section VII.
1-5. DESCRIPTION.
1-6.
This
large-screen, general-purpose
graphic
dis-
play
unit
has
been designed for
OEM
systems
ap-
plications. Specifications
are
listed
in
table
1-1.
Suggested
applications
are
listed
in
Section III.
1-7. SPECIAL FEATURES.
1-8.
Input
Modifications.
The
input
circuits to
the
X,
Y,
and
Z amplifiers
are
designed
to
permit
easy
modification for single-ended
or
differential
operation.
Ad~itionally,
the
input
termination
resist-
ance
and
the
input
attenuation
ratio
for
the
X,
Y,
and
Z amplifiers
can
be
changed.
Refer to
the
para-
grahs
on
input
modifications
in
Section III.
1-9.
Dynamic
Focus-astigmatism. Voltages propor-
tional
to
the
position
of
the
CRT
beam
are
applied
to
the
focus
and
astigmatism
elements
of
the
CRT.
This
causes
spot
size
and
shape
to
remain
constant
over
the
CRT
viewing
area.
Focus
is
also
corrected
for
changes
in
intensity
level.
1-10.
Phosphor Protection. A protection circuit
senses slow
or
static
deflection
signals
and
limits
beam
intensity
to
prevent
burning
of
the
CRT
phos-
phor
and
mesh.
1-11. CATHODE-RAY TUBE.
1-12.
The
CRT
has
an
aluminized
P31
phosphor
and
a
usable
viewing
area
of
approximately
13.5
inch
(34,3 cm) x 10.25
inch
(26,0 cm). A 28-kilovolt ac-
celerating
potential
produces a
bright
display
with-
out
harmful
X-rays.
1-13.
Other
phosphors,
as
well
as a number
of
low-
reflection
contrast
filters
are
available
as
standard
options. Refer to Section VII.
1-14. A rim
and
tension
band
are
fitted
around
the
faceplate seal line to provide protection
against
implosion injury.

faceplate
only.
Let
the
faceplate dry,
then
polish.
The
charge
can
also
be
removed
by
placing

PRINCIPLES OF OPERATION
4-1. INTRODUCTION.
4-2.
This
section
contains
function
descriptions
of
Model 1317 A, keyed to
an
overall
block
diagram.
The
block
diagram
and
schematics
are
located
in
Section VIII.
4-3. BLOCK DIAGRAM DISCUSSION.
4-4.
This
discussion
illustrates
the
function
of
each
circuit
group
(block)
and
the
relationship
of
the
blocks to
each
other.
It
is
based
on
the
overall
block
diagram,
figure 8-2.
The
conditioning
and
calibrating
controls,
as
shown
on
the
block
diagram,
illustrate
the
association
of
the
control
with a particular
block
and
are
not
necessarily
an
accurate
representation
of
the
control's action.
4-5. LOW VOLTAGE POWER SUPPLIES.
4-6.
This
block
(All)
provides
operating
power
to
all
the
other
blocks,
including
the
high
voltage
power
supply
and
some
of
the
CRT
elements.
Three
regu-
lated
dc
outputs
are
provided: +250 V,
+15
V,
and
-15
V.
The
+250 V supply
and
the
-15 V supply
are
adjustable.
The
+15 V supply
is
referenced
to
the
-15
V supply.
Several
other
voltages
are
derived
from
the
+250 V supply
by
means
of
voltage
dividers
and
avalanche
diodes.
Additionally,
an
unregulated
dc
output
to
the
high
voltage
oscillator
and
a 6.3
Vac
output
to
the
CRT
filament
are
provided.
4-7. HIGH VOLTAGE POWER SUPPLY.
4-8.
The
high
voltage
power
supply
(on A12
and
A13)
provides
the
high
operating
potentials
for
the
CRT.
The
rf
output
of
the
high
voltage
oscillator
is
stepped up
by
the
high
voltage
transformer
and
con-
ditioned
by
the
other
components
on
A12. A
sample
of
the
high
voltage
output
drives
the
error
detector.
The
error detector
controls
the
conduction
angle
of
the
high
voltage
oscillator
to
accomplish
regulation.
4-9. DEFLECTION SYSTEM.
4-10.
The
X-axis
amplifiers
(on
Al
and
A2)
and
the
Y-axis amplifiers (on A3
and
A4)
are
identical.
They
drive
the
horizontal
and
vertical
deflection
plates
of
the
CRT
proportionally
to
the
signals
applied
to
the
X
INPUT
and Y INPUT.
4-11. FOCUS AND ASTIGMATISM CIRCUITS.
4-12.
Samples
from
the X and
Y amplifiers, pro-
portional to
the
CRT
beam
position,
drive
the
focus
and
astigmatism
circuits (on A6).
These
circuits
develop correction
voltages
for
the
focus
and
astig-
matism
elements
of
the
CRT.
The
astigmatism
element
is
directly controlled
by
the
output
of
the
astigmatism
driver.
The
focus
element
is
connected
to
the
-3400 V output
of
the
high
voltage
power
supply.
This
supply
is
returned
to
(and
controlled
by)
the
output
of
the
focus driver.
The
focus
driver
also receives a
sample
from
the
Z-axis
amplifier
and
causes
focus corrections for
changes
in
beam
inten-
sity.
4-13. PHOSPHOR PROTECTION CIRCUITS.
4-14.
The
phosphor
protect
control
circuits
(on
Al
and
A3) detect
static
or slow
moving
deflection
voltages
and
activate
the
phosphor
protection
circuit
(on A5).
The
phosphor
protection
circuit
limits
the
output
of
the
Z-azis
amplifier
and
protects
the
CRT
mesh
and
phosphor
from
damage
that a static,
high-
intensity
beam
could cause.
4-15. Z-AXIS AMPLIFIER.
4-16.
The
high
voltage
supply
for
the
CRT
control
grid
is
returned
to
(and
controlled by)
the
output
of
the
Z-axis
amplifier
(on A6).
Consequently,
the
volt-
age
applied to
the Z INPUT
controls
CRT
beam
intensity.
The
Z-axis
amplifier
can
be
switched
to
permit
blanking
by
either
a positive
or
negative
voltage
at
the Z INPUT.
4-17. CIRCUIT DETAILS.
4-18. PHOSPHOR PROTECT CIRCUITS.
Phosphor
protect circuits
in
the X axis
and Y axis
are
identical
in
operation
so
only
the
X-axis circuits will be describ-
ed
(schematics 1 and
2).
4-19. Excessive
intensity
caused
by
a slow-moving
or
static
beam
can
cause
damage
to
the
CRT
ex-
pansion
mesh
or
phosphors.
When
deflection
speeds
are
reduced to a
potentially
harmful
level (less
than
approximately
76
mm/ms
(3 in.!
ms),
the
phosphor
protect circuits
limit
CRT
cathode
current.
This
current
limiting
action
occurs
because
of
circuit
actions
described below.
4-20. Differential output, from
the
X-axis
voltage
differential
amplifier
stage
(schematic
1),
is
applied
to
X-axis
emitter
follower
stage
(schematic
2).
Differ-
ential
output
of
this
stage
is
proportional
to
the
beam
position
in
the
X-axis direction,
and
is
applied
to
the
voltage
sensor
stage. A voltage
change
at
the
col-
lector
of
either
voltage
sensor
reduces
the
voltage
on
A1C19.
When
the
voltage
on
A1C19
is
sufficiently
reduced,
the
phosphor
protect
control
is
activated
and
produces a positive
voltage
at
its
output.

is
applied
to
the

of
the
phosphor

circuit
on
the
Z-axis

(schematic

voltage
at
this
point
causes
A5VR4
to
clamp
the Z-axis
output
at
approximately
14 V.

and

4-23.
Some
applications
make
it
necessary
to
obtain
a
bright
display
of
a slow-moving
or
sta
tic
beam.
Setting
the
phosphor
protection
switch
to
the
OFF
position
disables
the
phosphor
protection
circuit
by
grounding
all
inputs
to
the
circuit.
4-24. DYNAMIC FOCUS/ASTIGMATISM CIRCUITRY.
The
circuits
that
change
focus
and
astigmatism
volt-
ages
with
reference
to
beam
position
are
quite
similar.
Only
dynamic
focus
circuits
are
described here,
and
reference
to
dynamic
astigmatism
is
made
only
where
circuit
variation
is
involved
.
4-25.
Circuit
action
of
dynamic
focus
is
identical
for
the X axis
and Y axis
so
only
the X axis
is
discussed
here.
The
differential
voltage
proportional
to
beam
position
is
taken
from
the
input
of
the
X-axis
ampli-
fier
emitter
follower
stage
(schematic
2)
and
applied
to
the
X-input
amplifier
stage
on
the
dynamic
focus
assembly
(schematic
8).
In
the
dynamic
focus as-
sembly,
the
output
of
the
X-input
amplifier
is
applied
to a diode
shaping
network
that
generates a parabolic
voltage
as a function
of
beam
position
(figure 4-1).
4-26. With
A6FXl
and
A6FX2
adjustments
in
full
ccw position
(schematic
8),
the
diode
shaping
network
is reverse
biased
and
the
X-input
amplifier
collector
voltages
will
vary
linearly
as
the
differential
voltages
change
on
their
bases
(figure 4-2).
Adjusting
A6FXl
and
A6FX2
as
described
in
Section V establishes
a
reference
voltage
level
on
X-input
amplifiers
at
which
linearity
of
the
voltage
ramp
is
altered.
4-2
/ (
4-3
blank)
4-27.
The
output
voltage
of
the
diode
shaping
net-
work
is
applied
to a current
amplifier
and
converted
to
a
current
signal.
These
current
signals
from X-and
Y-input
amplifiers
are
summed
and
applied
to
a com-
plementary
output
amplifier.
The
complementary-
output
amplifier
output
is
a correction
voltage
applied
to
the
floating
focus
supply
in
the
high
voltage
power
supply
(schematic
11).
These
circuit
effects
serve
to
adjust
beam
focus
automatically
in
relationship
to
beam
position
on
the
CRT
face.
Glli§B
If
a
pattern
consisting
of
only
a few
dots
is
present
on
the
CRT,
the
phosphor
pro-
tection
circuit
will
detect
deflection
and
disable
the
phosphor
protection
circuit.
If
the
beam
current
is
high
and
the
duty
cycle is
near
100%,
the
average
current
at
each
dot
may
be
sufficient
to
damage
the
CRT. Therefore,
caution
must
be
used
in
setting
the
INTENSITY
control.
4-28.
Dynamics
focus
and
dynamic
astigmatism
vary
only
in
that
the
dynamic
focus
circuit
is
designed
to
provide a
relatively
low
output
impedance
to
suppress
noise feedback from
the
normal
focus circuit.
