Focusing coil current shall be determined at the focus setting used in the astigmatism test. 5/ The

15、two sets of neck supports, referenced in method 5101, shall be spaced 1.125 inches (28.58 mm) and 3.375 inches (85.73 mm) below reference plane. 6/ Line width A shall be the maximum line width obtained in the astigmatism test. 7/ With a single line, 4.5 inches (114.30 mm) in length and 1/60-second d

16、uration, repeated at a rate of 60 Hz, modulate grid No. 1 with 1-microsecond pulses. Adjust the peak beam current to 200 A dc and focus for the most circular spot at the center of the screen. Display a partially merged nonlinear raster and note the orientations for greatest and least mergings as the

17、 raster is rotated. Maintain this focus and proceed according to method 5226, to determine the line widths for those two orientations. Astigmatism (the ratio of the maximum to the minimum line width) shall not exceed the value specified. Provided by IHSNot for ResaleNo reproduction or networking per
