PRELIMINARY
FOCUS OFFSET CONTROL
Focus Offset control starts when it receives the Focus Offset control start command $842X from micom. Focus
Offset control ends when the focus error amp output below 1/2VCC after the focus output with 1/2 VCC at the focus
error amp final output terminal. The voltage per 1 step of the focus offset control is approximately 40mV. The 4 bit
resistance DAC changes from 320mV up to -320mV in 1 step, after which 1/2 step, approximately -20ms offset, is
applied. The offset dispersion after Focus offset control exists between -20mV - +20mV. The Febias Offset can be
changed in 10mV step within the micom's
±
100mV range after focus offset control. The required per 1 step is
2.5ms; for 4 bits and total of 16 steps, the maximum required time is 128ms.
For focus offset readjust, 4-bit DAC is reset by $867, and reset can be canceled only when the $86FX applied D3
bit is changed from 0
→
1. The Febias DAC latch block reset for electrostatics and operation error is reset by
micom DATA and not by RESET terminal, the system reset.
