PRELIMINARY
FEBIAS OFFSET SETTING
Febias Control
The FEBIAS offset control is automatically controlled to 0mV and can be controlled to
±
200mV. After the focus
offset automatic control ends after FEBIAS offset automatic control, the command sets the internal positive and
negative offsets in 20mV units to the micom.
RF SUMMING AMPLIFIER APPICATION
The RF I/V AMP can be controlled to 0.5X 8Step up to 1X - 4X CD-R and CDRW. The information related to CDR,
CDRW disc detector is output as RFO level through the ISTAT. The RFO offset control is installed to prevent RF
level clipping during low RFO voltage.
