NOTES:
1. This test to be performed at the conclusion of the holding period.
2. All electrical tests are to be made on each gun separately.
3. As measured with a 2 inch x 2 inch (50.8 x 50.8 mm) raster using type 3 photronic cell without eye correction,
calibrated in footcandles of illumination from a light source having a color temperature of 2700K.
4. Corresponding traces of each gun should be within 1 degree of each other.
5. Under stable operating conditions (method 5231), the position of either spot will not shift with changes in
intensity by more than 0.025 inch (0.64 mm).
6. Ratio of deflection factors of corresponding sets of deflection plates (larger deflection factor divided by lower
deflection factor) shall not exceed 1.15.
7. With a raster pattern the size of which is adjusted so that the widest points of the pattern just touch the sides
of a square, 3.075 inches (78.11 mm) on a side, no point on these pattern sides will lie within an inscribed
square, 2.925 inches (74.30 mm) on a side.
8. The deflection of one beam when balanced dc voltages are applied to the deflection electrodes of the other
beam will not be greater than the indicated value.
9. Maximum voltages applied to base, deflection plates and A2 only.
10. Tube type 5SP2A has been deleted from this specification sheet.
11. This specification sheet uses accept on zero defect sampling in accordance with MIL-PRF-1, table III.
