General Information—608
Electrical Characteristics
Characteristic Performance Requirement
Uniformity Light output does not vary more than 20% in the crt
quality area, at moderate intensity 34 cd/m? (10 fL).
Measured with the quality area flooded by a raster, 60
Hz refresh rate, 320 horizontal lines.
#1 0.031 cm (0.012 in) or less, anywhere inside the quality
area, with the intensity set to produce 170 cd/m? (50 fL)
brightness, with a full screen raster refreshed at a 60 Hz
rate. Measured with the shrinking raster method.
#2 0.026 cm (0.010 in) or less, at 0.5 wA beam current.
Measured with the shrinking raster method.
Resolution Spot size does not vary more than 10% in the quality area
at a constant intensity.
