Febias Offset Setting
Febias Control
The FEBIAS offset control is automatically controlled to 0mV and can be controlled to
±
100mV. After the focus
offset automatic control ends after FEBIAS offset automatic control, the command sets the internal positive and
negative offsets in 10mV units to the micom.
RF SUMMING AMPLIFIER APPICATION
The internal switch for the 1x and 2x filter select turns on when it is 1x and off, when 2x. The time constant to fit
the set. The RF 1/V AMP can be controlled to 0.5X 16Step up to 1X - 8X 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 and the RFO offset information is output to ISTAT
so that micom can know the RFO information.
