Note11. All vertical and EW adjustments are specified at nominal vertical settings, which means:
a)
VAMP = 100% (I
VAMP
= 135

b)
VSCOR = 0 (Pin19 Open

c)

d) f

= 70kHz
Note12. The superimposed logarithmic sawtooth at VSCOR (Pin19) tracks with VPOS, but
not
with
VAMP settings.
The superimposed waveform is described by
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.
