Note 11. All vertical and EW adjustments are specified at nominal vertical settings, which means:

a) ∆VAMP = 100% (IVAMP = 135µA

b) ∆VSCOR = 0 (Pin19 Open–Circuit)

c) ∆VPOS centered (Pin17 forced to GND)

d) fH = 70kHz

Note14. The superimposed logarithmic parabola at EWTRP (Pin20) tracks with VPOS, but not with

VAMP settings.

Note15. If fH tracking is enabled, the amplitude of the complete EWDRV output signal (parabola +

DC shift + trapezium) will be changed proportional to IHREF. The EWDRV low level of 1.2V

remains fixed.
