INTRAC-305	TECHNICAL DESCRIPTION
	illuminated. The alarm may be viewed using the Show Alarms
	menu.
	The Soft Limits are set in the Configuration - Soft Limits menu.
Note	In either Manual (P) or Manual (A) mode the antenna may be
	driven through the soft limits with no warning.
AXES POSITION	Resolver units are fitted to the driven axes of the antenna.
	These units supply positional information to the INTRAC’s
	resolver interface circuits.
	Depending on the system “Extended Azimuth” or “EG-01”
	and/or “Geared Pol” offsets may need to be set.
	Fine Tune offsets may be set to calibrate the resolver outputs
	to the actual antenna pointing angle.
TRACKING SIGNAL	An L-band Integrated Beacon Receiver (IBR-L) is an option
	with the INTRAC-305. When fitted this receiver is tuned to an
	L-band frequency by the INTRAC based on the “Beacon
	Frequency” set for the satellite. If the beacon frequency of the
	satellite to be tracked is not in the L-band a Block Down
	Converter will be required to convert the signal to L-band.
	The calculation of the correct L-band frequency for the IBR-L is
	performed automatically by the INTRAC for BDCs with
	standard local Oscillator frequencies so that the beacon
	frequency may be entered at the actual receive frequency.
Note	If an IBR-L is not fitted the INTRAC requires a dc voltage level
	which is proportional to the received signal strength from the
	satellite.
