All readings of beam current (Ib3) shall be in addition to the reading obtained for method 5201, anode No. 3 current. For oscilloscope use, the mean

18、potentials of 1D2 and 3D4 with respect to ground shall be zero. 2. It is recommended that the deflecting electrode circuit resistance be approximately equal. Higher resistance values up to 5.0 megohms may be used for low-beam current operation. 3. With the beam cutoff, the post-accelecrator anode (A

19、3) shall draw 15 Adc maximum. 4. Spot adjusted for least astigmatism. 5. With a 2.5-by 2-inch rectangular raster centered on the face of the tube, the raster edge shall not deviate form straight parallel lines by more than 0.040 inch on the left and right edges nor by more than 0.0515 inch at the to

20、p and bottom. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-1/1386F 56. The post-accelerator spiral band lower end and the geometry adjust are connected internally. By adjusting the potential on this electrode combination, pin cushion and b

21、arrel distortions are minimized. 7. Normally operated at accelerator potential, linearity improvements can be obtained in the vertical trace by proper adjustment of deflection plate shield voltage. 8. For the 102 direction: Divide the axis into five successive 1/2 inch intervals symmetrically locate

22、d with respect to the geometric center of the tube face. The percentage difference (DFU)between deflection factors of the center interval and any other interval shall not exceed the limit specified. 9. A hammer-drop shock testing machine shall be used, consistent with MIL-PRF-28800. The tube may be

23、clamped as in the vibration test or mounted directly on the shock machine. With test potentials applied, display a circle or raster. Using a hammer-drop height of 6 inches, apply three blows each in directions 1D2, 3D4, and base-to face. Momentary failure of operation during shock is permissible pro

24、vided normal operation is deflection factor, spot position, and grid cutoff voltage. In addition, there shall be no evidence of damage to the internal structure. 10. Range for oscilloscope use: -55 to +20 Vdc. 11. Following temperature stabilization, the tube shall meet requirements under pattern di

25、stortion, line-width, and anode No. 3 current; all voltages and settings being those obtained at room temperature with 25 K resistors in series with geometry, shield and astigmatism adjust electrodes. 12. An accept on zero defect sampling plan (see MIL-PRF-1, table III) shall be used for conformance
