48. This is a current input. The indicated value of the nominal bias current is obtained at the nominal setting of the gain
(white point) control. The actual value of the bias current depends on the gain control setting of each channel. As a
result the ‘black current’ of each gun is adapted to the white point setting so that the background colour will follow
the white point adjustment.
49. The beam current limiting and the vertical guard function have been combined on this pin. The beam current limiting
function is active during the vertical scan period.

Note
1. During vertical retrace the width is 22
s and during the lower part of the picture 12 s. In the other conditions the
width is 5.7
s and the gating is continuous.
