Horizontal EHT comp.:This item controls the influence of the input signal IBEAM on the output
AFC EHT comp.:
Micronas
If Vertical EHT compensation = -128 the outputs VD+ and VD- are
independent of the input signal IBEAM.
E/W according to the following equation:
If Horizontal EHT compensation = -128 the output E/W is independent
of the input signal IBEAM.
Deviation of the horizontal phase caused by high beam current (e.g.white
bar) can be eliminated by this control item. The beam current dependent
input signal IBEAM is multiplied by AFC EHT compensation. Additional to
the control items Vertical angle, Vertical bow and Horizontal shift, this pro-
duct influences the horizontal phase at the output HD according to the
following equation:
