|  MIL-D-81347C(AS)
(a) Accuracy Under Nominal Conditions -Nominal condi-
tions are defined as the temperature range of 10C to 40C, and the range of input power within the
bounds of Limits 2 and 3 of `Figure 3, MIL-STD-704 as modified by 3.3.12.1. Accuracies under
these conditions shall be as follows:
1 . The X and Y total harmonic distortion of the sinu-
soidal conic generation signals shall be less than 1%.
2. The phase difference between X and Y sinusoidal
conic generation signals shall be less than one degree.
3 . A change in the digital signal shall produce a cor-
responding change in the analog signal within one LSB.
-- . The magnitude accuracy of X relative to Y shall be
4
less than +1%.
-- . The absolute accuracy of X or Y shall be less than
5
+2%.
(b) Accuracy Under Extreme Conditions_ - Extreme condi-
tions shall be as defined in 3.3.10. Accuracies under these conditions shall be as follows:
1 . The X or Y total harmonic distortion of the sinu-
soidal conic generation signals shall be less than 2%.
2. The phase difference between the X and Y sinusoidal
conic generation signals shall be less than 2.
3 . A change in the digital signal shall produce a cor-
responding change in the analog signal within one LSB.
4 . The magnitude accuracy of X relative to Y shall be
less than +2%.
5 . The absolute accuracy of X or Y shall be less
than +4%.
(2) ' Z" Axis Video - Positive going video signals shall be DC
coupled to the video amplifier of the Auxiliary Display for intensity modulation of the CRT. Video
amplitude shall be proportional to writing speed.
(3) Unblank - The ADL shall provide a positive going voltage
level to the Auxiliary Display for unblinking the CRT. The unblank signal shall have the same dura-
tion as the video signal, but shall have constant amplitude.
3.5.4.4.3,4.2
Output Signal Characteristics
3.5.4.4.3.4.2.1
Auxiliary Display - The ADL input/output signals to and from
the Auxiliary Display shall be as follows:
Triaxial Transmissions - All signals to the Auxiliary Display
3.5.4.4.3.4.2.1.1
shall be transmitted via Amphenol 421-033 cable or equivalent terminated in a differential amplifier
whose input impedance shall be 90 to 95 ohms and 100 pf maximum. The coaxial cable shall not exceed
100 feet.
