East-West output stage
In order to obtain correct tracking of the vertical and
horizontal EHT-correction, the E-W output stage should be
dimensioned as illustrated in Fig.12.
Resistor R
EW
determines the gain of the E-W output stage.
Resistor R
c
determines the reference current for both the
vertical sawtooth generator and the geometry processor.
The preferred value of R
c
is 39 k
which results in a
reference current of 100
μ
A (V
ref
= 3.9 V
The value of R
EW
must be:
Example: With V
ref
= 3.9 V R
c
= 39 k
and V
scan
= 120 V
then R
EW
= 68 k
.
