FOCUS / TRACKING channel

The focus and tracking channel is the voltage control drive using BTL .

The focus and tracking is the same composition.

The relationship between the differential voltage between FOIN and REF and the output voltage

is shown in below Figure.

The voltage gain [Gvo] is 5.0 [V/V].

The maximum range of output swing is limited around 7.5 volts,in case of VM4 is above 10 volts.
