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

Note12. The superimposed logarithmic sawtooth at VSCOR (Pin19) tracks with VPOS, but not with

VAMP settings.

The superimposed waveform is described by

with ’d’ being the modulation

depth of a sawtooth from –5/6 to +5/6. A linear sawtooth with the same modulation depth can

be recovered in an external long–tail pair.

Note13. The output signal at EWDRV (Pin11) may consist of parabola + DC shift + trapezium correc-

tion. These adjustments have to be carried out in a correct relationship to each other to avoid

clipping due to the limited output voltage range at EWDRV.
