Models 1332A, 1333A, 1335A& 13365
Introduction
Models 1332A. 1333A. 133SA. and 13368 are high-quality cathode-ray
tube displays designed to satisfy a wide range of OEM medical
and elcctronic instrument display nccds. They provide optimum
performance when uscd as continuous tone imaging displays. Continuous
tone images are so called because the image space in the X- Y
plane is mied with a continuum of brightness levels ranging from
black to maximum brightness. where the brightness represents some
physical parameter such as radar return amplitude. ultrasonic reflectivity
of body tissues. etc.. having a varying spatial distribution of
magnitude.
Brlght tor Easy Viewing
Model 1332A: has a large 9.6 X 11.9 cm display area with the resolution
and picture quality required fot medical diagnosis systems plus a
bright display for differentiating between many gray shades. or for
vie~ng in brightly lighted areas. Option 530 provides even greater
brightness with up to 500 cd/mt liRe brightness.
Spot size is only 0.3 mm over the entire quality area and over the
full range of intensity levels. This resolution makes the 1332A weil
suited for applications requiring sharp focusing on multiple gray
shades or varying writing speeds with frequent video drive level
changes. e.g., alphanumeric characters mixed with traces, curves, or
graphs.
The large viewing area and bright display make the 1332A ideal for
the OEM with both visual and some photographic requiremenls. Display
brightness leis you view the display in high ambient light conditions
while maintaining resolution and gray shades for photographic
work. Whenever uniform phO}ographic recording of the display becomes
critical. the 1333A or T3365 should be used.
Optlmlzed tor Photographing
Model 1333A: hasa high resolution CRTwithan 8 x 10cmviewing
arC'd specifically optimized for photographic applications such as
gamma camera systems. The 1333A's combination of high resolution.
e~cellent uniformity. and speed permits crisp. easy-to-read. diagnoslic-quality
photographs to be obtained from state-of-the-art nuclear.
ultrasonic. thermographic. and X-ray scanning systems.
Spol size is a crisp 0.2 mm everywhere on the 8 X 10 cm display.
which allows resolution of 193 354 picture elements. The spot remains
round and sharply focused in all areas of the screen and at
varying intensity levels. eliminating the need to readjust focus or
astigmatism controls.
Light output uniformity is fully specified. both overall and for small
increments. which assures you that the information content of the display
is an accurute rcpresentation of the input signals. Additionally.
light output drift is specified. including all effects of the Z-a~is amplilief.
high voltage supply. und CRT. A regulated dc CRT filament
voltage is also used to ussure constant light output independent of line
voltage nuctuations. The regulated dc filament voltage also reduces
the possibility of interference patterns resulting from correlation between
input signal frequencies and the high voltage oscillator or power
line frequencies.
Variable Persistence, Storage
Model 1335A: is a high resolution 8 X 10 cm storage display which
offers medical and instrumentation OEM users a variable persistence
storage CRT display with outstanding performance and picture quality.
In the non-storage mode (called CONVENTIONAL). the CRT
operates similar to a mono-accelerator conventional CRT wilh an exceptionally
small spot thai focuses uniformly over the entire quality
area. Resolution is approximately 40 lines per cm (100 lines per in.).
In addition. spot size is relatively independent of intensity settings or
Z-axis input signals. eliminating lhe need to refocus at each intensity
setting. The storage writing speed remains stahle through use of regulated
CRT filament voltage and stahle Z-axis amplifier design.
The same excellent CRT performance is maintained in the Variable
Persistence operating mode. Persistence is continuously adjustable
with a front panel control from approxirnately 0.205 lo > I minute.
This mode allows you to eliminate nicker on same presentalions by
increasing the persistence lo match lhe refresh rate. The variable persistence
mode is selected by pressing lhe WRITE pushbutton.
The storage CRT is presello store dots having a Z-axis width of I
llS or greater for up to 30 minutes. The STORE mode offers lhe grealest
conlrasl because the background is complelely dark. Stored resolution
is over 20 lines per cm (50 lines per in.) and stored lraces relain
sharp details for up to 1 minute in WRITE mode. 30 minules in
STORE mode.
The Model 1335A offers users nexibility in selectina ERASE.
STORE. WRITE. CONVENTIONAL. and VARIABLE PERSIS.
TENCE modes. These modes can be selected with the manual front
panel controls. remote program inputs. or a combination of both.
Resolution up to 140 lines/cm
Model 1336S: consists ofan 8 X 10cm display module (1336A) and
a separate power supply module (1336P) for mounting nexibility.
The display offers a choice of 140 lines/cm or 90 lines/cm (Oplion
005) resolution fot all high-resolution imaging requirements such as
mulli-imaging fot nuclear or ullrasound medical diagnoslic systems.
scanning electron microscopes. and scanning auaer microprobes. A
mono-accelerator CRT with an accelerating potential of approximately
5 kV produces a smalI. high inlensily spot wilh only 100 walls
power consumption.
The CRT is designed lo prevenl spurious light from reaching phOlographic
film during lang time exposures. Light output uniformity is
tested to assure lhat lhe information conlent of the displayed image is
an accurate representation of lhe input signals.

13365
CRT'.
The 1332A. 1333A. and 133SA have post denection accelerator
CRTs to assure a briaht. crisp trace. The 1336S display uses a monoaccelerator
CRT desian to achieve 140 lines/cm resolution at center
screen with low power consumption. An opaque aluminum layer behind
the phosphor (except in model 1336S. which is non-aluminized)
enhances trace briahtness.
Reaulated. low power write aun and nood gun filaments assure a
conslanrlight output under varying line voltage conditions. More importantly.
the low power filament operation significantly extends
CRT lire and eliminates arid and other stray emissions common to
older. less efficient designs.
Models 1332A. 1333A. 1335A (Opt 330). and 1336S are listed
with Underwriters Laboratones in accordance with the UL 544
Medical Safety Standard which defines detailed patient protection
requirements. Regular inspection of Gur production facility by UL
assures you thatthis patient protection is built into the display that
you purcha!iC.
Electronlc8
Model. 1332A. 1333A, .nd 1335A
The X and Y amplifiers have 70 ns rise time (bandwidth is 5 MHz)
and the Z.axis blltnking amplifier has a 25 ns rise time. When raster
X und Y umplifier response is required. Model 1332A has an Option
available to obtain 25 ns rise times. All amplifiers are fully differenlialltnd
opera te atlow power levels for stable. drifwree performance
over wide ranges of operatinglemperatures.
The lime required to make uny size movement on the CRT. includ.
ingthe response time for the ampiifiers to settle within one spot diameter
of final position. is less than 300 ns. This means that many
thousunds of vectors und character!i can be written on the display
withoul nicker.
Modet 13385 (1336A .nd 1336P)
The I 336A's denection amplifiers settle to within one spot diameter
in < 500 ns after receiving an input step command. All amplifiers are
fully differential and opera te allow power levels for slable operation
und minimum wurm.up time. Dynumic focus circuits automatically
correct far spot position to assure optimum resolution over the entire
CRT face. A regulated ~ CRT filltmer.t supply assures astabte light
output.
