It is recommended that the deflection electrode circuit resistances be approximately equal.
2/
This tube is designed for optimum performance when operating at an Eb3/Eb2 ratio of 2.0. Operation at other ratios of Eb3/Eb2
may result in changes in deflection uniformity and pattern distortion.
3/
All tests are to be performed with the tube shielded.
4/
This test to be performed at the conclusion of the holding period.
5/
This test is to be made with a maximum rated voltage (Eg1 maximum negative voltage) applied to the base pins.
6/
Useful scan.
The useful scan in the 1D2 direction is ± 1.3125 inch (33.34 mm) from the tube face center.
a.
The useful scan in the 3D4 direction is ±0.75 inch (19.05 mm) from the tube face center.

All portions of a raster pattern, adjusted so its widest points just touch the sides of a 2.295 inches (58.29 mm) by 1.530 inch
(38.86 mm) rectangle, will fall within the area bounded by the 2.295 inches (58.29 mm) by 1.530 inch (38.86 mm) rectangle and an
inscribed 2.205 inches (56.01 mm) by 1.470 inch (37.34 mm) rectangle.
8/
Use a raster size of 2.25 inches (57.15 mm) by 1.50 inch (38.10 mm), and a type 3 photronic cell without eye correction calibrated
in foot candles of illumination from a light source having a color temperature of 2,700°K.
