GENERAL INFORMATION
1-1. INTRODUCTION.
1-2. This manual provides operating and servicing
information for the Hewlett-Packard Model 1317 A
High Speed Graphic Display (figure 1-1). 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.
1-3. This section contains general information per-
taining to the instrument. Table 1-2 lists the abbre-
viations used throughout this manual, except in
Section VI. The parts list in Section VI is a computer
printout and uses computer supplied abbreviations.
1-4. Available options 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.
1-15. Complete CRT specifications are located in
table 1-1.
1-16. WARRANTY.
1-17. The instrument is certified and warranted as
