The test conditions shall be anode voltage (relative to cathode) 4,000 V minimum and beam current 60 A
13、maximum. The screen characteristics shall comply with the following minimum limits: cB5 = 400 cB; G5:1 = 4.

14、 or No. 122 and 70 degree deflection coil JEDEC No. 118. 4/ For P25 phosphor, apply full raster to prevent screen burning. 5/ The phosphorescent light intensity observed (t) seconds after completion of the nth raster to the tube is Dt(N). cBf shall be the fluorescent light output under continuous ra
15、ster excitation. The screen characteristics shall be measured under the following conditions: a. Raster size (focused beam) 50 cm2with tube defocused to a spot approximately 0.25 cm (0.1 in) in diameter. b. Beam current: The tube operated at a current to produce 0.05 watt at the specified test volta
16、ge. c. Duration of raster: 1/60 second. d. Distance of raster from axis of calibrated 931VA multiplier tube: 30 cm (11.81 in). e. Red or white light: Sufficient to de-excite the phosphor before build-up measurements so that the results are within 3 cB of those that would have been obtained after tot
17、al de-excitation. 6/ The maximum diameters of “dead“ and “color“ spots shall be .060 inch. 7/ The tube shall be supported vertically on its face and rotated by a suitable adjustable turntable mechanism which will permit the neck to run true to the center of rotation of the turntable. A dial indicato
18、r perpendicular to the cone surface and .375 inch (9.53 mm) above the back of the faceplate metal lip shall be used to determine the amount of neck and bulb misalignment. The variation shall be no greater than the specified limit. 8/ With the tube supported as specified in 7/, the face tilt shall no
19、t exceed .375 inch (9.53 mm). Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-1/1072H 5 NOTES: 1.
