184.108.40.206 Refresh Rate. - The Display shall have a refresh rate of
60 HZ ± 5%.
220.127.116.11 Writing.- The display writing speed shall be defined by
Figure 2 for a basic sine wave input. All timing tolerances shall be
18.104.22.168.1 Blanking. - The blanking signal bandwidth shall be 2 MHz
22.214.171.124 Positional Stability. - Screen center (O volt inputs on pins
A and H of Table I) shall not change by more than± .035 inches during
all testing of the Image Display.
126.96.36.199.1 Deflection Accuracy.- The display shall be aligned in
accordance with Table II to an accuracy of ±.010" at screen center.
The accuracy tolerance shall increase linearly to a nuiximum of ± .020"
at full screen deflection.
188.8.131.52.2 Environmental Accuracy.- The deflection accuracy toleranes
shall increase under environmental testing to an accuracy of ±l.020" at
screen center. The accuracy tolerance shall increase linearly to a max-
imum of ±0.030" at full screen deflections
184.108.40.206.3 Resolution.- The horizontal and vertical resolution for
the displayed symbology shall be 0.007 inches.
220.127.116.11.4 Deflection Convention.- With the Display control surface
at the top a positive input on the horizontal and vertical input lines
shall cause the beam to move to the left and up from screen center.
3.5.6 Brightness.- With 1" diameter circle of 25 KHz frequency and
an unblinking time of 0.04 milliseconds and a 60Hz refresh rate the Display
shall have a brightness of 700 foot lamberts measured between the 50% points
of the circle line width.
3.5.7 CRT Protection.- Deflection failure safety circuits shall be
provided such that a loss of beam deflection shall be sensed and the CRT
electron beam current automatically cut off and the self test circuitry
18.104.22.168 Input Protection.- The CRT shall not be damaged (including
bum marks) by the application of power in the absence of deflection or
blanking input signals.
3.5.8 Stray Reflections.- Stray reflections shall be minimized by
the use of high efficiency anti-reflective coatings on the CRT face.
3.5.9 Sealing.- The CRT face shall be sealed from the Display
3.5.10 Touch Temperature.- The maximum touch temperature allowable
on the control panel shall be less than 25°F above the ambient temperature.
