MIL-PRF-1/1386F
6.
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 barrel 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 located 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 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 provided 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 distortion, 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 inspection, part 1.
13. This test to be performed at the conclusion of the holding period.
