Specification—475
line frequency of 48 to 440 hertz. Maximum power
consumption is 100 watts at 115 VAC, 60 hertz.
CATHODE-RAY TUBE
Graticule Area
Eight by ten centimeters.
Phosphor
P31 is the standard phosphor with P11 offered as an
option.
ENVIRONMENTAL
Temperature
Operating: —15°C to +55°C; Storage: — 55°C to +75°C.
Altitude
Operating: to 15,000 feet. Maximum operating
temperature decreased 1°C/1,000 feet above 5,000 feet.
Storage: to 50,000 feet.
Humidity (Operating and Storage)
5 cycles (120 hours) referenced to MIL-E-16400F.
Vibration
15 minutes along each of three major axes at a total
displacement of 0.025" peak to peak (4 g's at 55 hertz)
with frequency varied from 10 hertz to 55 hertz to 10 hertz
in one minute sweeps. After sweep vibration in each axis,
hold the frequency steady at each major resonance for 3
minutes, or if no such resonances are found, hold at 55
hertz for 3 minutes.
Shock (Operating and Nonoperating)
30 g's 1/2 sine, 11 milliseconds duration, 2 shocks per
axis each direction for a total of 12 shocks.
Transportation
Tested to National Safe Transit Committee Procedure
1 A, with a 30-inch drop.
SUPPLEMENTAL INFORMATION
The supplemental information listed here represents limits that, when met, ensure optimum instrument operation. They
are, however, not instrument specifications but are intended to be used only as maintenance or operational aids.
VERTICAL DEFLECTION SYSTEM Common-Mode Rejection Ratio
Low-Frequency Linearity
There should be no more than 0.1 division of
compression or expansion of a two-division signal (at center
screen) positioned to the upper and lower extremes of the
graticule area.
Bandwidth Limiter Bandwidth
The — 3 dB point should be between 15 and 25
megahertz.
Step Response Aberrations
There should be less than +4%, -4% , or a total of 4%
peak to peak aberration on a positive-going step in the
5m V /D IV position of the VOLTS/DIV switch. Add 3%
when checking a negative-going step or when checking for
aberrations while operating in the added mode.
At least 20:1 at 1 kilohertz for common-mode signals of
8 divisions or less.
Trace Shift As Variable Is Rotated
Adjustable to 2 divisions or less.
INVERT Trace Shift
One division or less when switching from normal to
inverted.
Input Gate Current
1 nanoampere or less (0.2 division at 5 mV/division)
from +20°C to +30°C. Four nanoamperes or less (0.8
division at 5 mV/division) from —15°Cto +55°C.
Channel Isolation
At least 100:1 at 50 megahertz.
