Table 1-1. Specifications
VERTICAL AND HORIZONTAL AMPLI-
FIERS
1-2
RISE TIME: <70 ns (10% to 90% points) for full
screen deflection.
BANDWIDTH:
dc to 5 MHz (3db down) for 4
inch (10.2 cm) deflection.
PHASE SHIFT:
<0.10 to 50 kHz and <10 to 250
kHz for full screen signal inputs.
DEFLECTION FACTOR:
100 mV linch (1 Volt
peak to peak for 10 inch deflection).
GAIN ADJUST: allows continuous adjustment
of deflection factor from approximately 80
m V linch to 130 m V linch. (Front panel Gain
control has 1.75:1 range.)
POLARITY:
positive vertical input moves beam
up; positive horizontal input moves beam to
the right.
LINEAR WRITING TIME:
<100 ns/inch (39,4
ns/cm).
LINEAR WRITING SPEED:
>10
inchesllLs (25,4
cmllLs).
DIAGONAL SETTLING TIME: signal settles to
within 1 spot diameter of final value in <IlLs
for any on or off screen movement. Off-
screen deflection not to exceed one screen
diameter.
REPEATABILITY: <0.15% error (of full screen)
for re-addressing a point from any direction
on or off screen. Off screen deflection not to
exceed one screen diameter.
SEQUENTIAL POINT PLOTTING TIME:
signal
settles to within 0.010 inch (0,254 mm) of final
value in <200 ns for any 0.10 inch (2,54 mm)
step.
CROSSTALK: <0.015 inch (0,381 mm) with one
input terminated in 50n and the other excited
by a IV 500 kHz signal.
SPOT JITTER AND MOTION: <0.010 inch (0,254
mm).
INPUTS: through BNC conn ectors where
shield is floating.
INPUT RC:
driven side 10kn shunted by ap-
proximately 40 pF. Shield input is 47n to
ground (for differential operation this is re-
placed by 10kn). A switch able 50n termination
between shield and center conductor is also
provided.
MAXIMUM INPUT:
±50V (dc
+
peak ac) with
10kn internal termination, ±5V (dc
+
peak ac)
with 50n internal termination.
POSITION:
front panel controls allow zero in-
put to be set off-screen in any direction from
anywhere within the viewing area.
DYNAMIC RANGE: at least ±1-1/2 screen dia-
meters from center screen.
DRIFT: 0.05 inch/hour (1,27 mm/hour) and
0.10 inch (2,54
mm)
in 24 hours with covers
installed.
Z-AXIS AMPLIFIER
RISETIME: <20 ns (c.w. bandwidth:: 15 MHz).
INPUT: BNC connector.
INPUT RC:
approximately 10kO shunted by
approximately 60 pF. 500 termination may be
selected with internal switch.
MAXIMUM INPUT:
±50V (dc
+
peak ac) with
10kO internal termination. ±5V (dc + peak ac)
with 500 internal termination.
BLANKING RANGE: 0 to IV (see balance).
BLANKING POLARITY:
+
UNBLANKS.
BALANCE:
internal adjustment provides ±1 V
offset (continuous) to blanking range.
GAIN ADJUST: extends blanking range by over
2.5:1 (continuous).
CATHODE RAY TUBE
TYPE:
Post deflection accelerator, 28.5 kVaccel-
erating potential, P31 phosphor, aluminized, is
standard (refer to Section VII for additional
phosphor selection), electrostatic focus and
deflection.
VIEWING AREA:
17 inch (43,2 cm) diagonal
CRT, useable viewing area at least 13.5 inch
(34,3 cm) x 10.25 inch (26,0 cm).

RESOLUTION: Approximately 50 line/inch
(19,7 lines/cm)
measured with a shrinking
raster.
LINE BRIGHTNESS: 50 foot lamberts at a writ-
ing speed of 0.1 inchllLs), (0,25
cmllLs), 60
Hz refresh rate, P31 phosphor, 0.020 inch (0,51
mm) spot size.
CONTRAST RATIO:
4:1 or greater measured by
photometrically summing the trace and back-
ground brightness.
GEOMETRY: <3% pincushion and barrel distor-
tion over useable display area.
LINEARITY:
<3% of full scale along major axes.
PHOSPHOR PROTECTION: automatically de-
tects absence of deflection and limits beam
current to a safe but viewable level.
DYNAMIC FOCUS:
built-in circuitry automati-
cally corrects spot geometry
fo~
position loca-
tion and beam intensity (video drive level).
TRACE ALIGN: Rotates X-axis into geometric
alignment with the CRT viewing area.
