Advantech user manual Specification & Options INTRAC-305

SPECIFICATION & OPTIONS	INTRAC-305
SPECIFICATION
Tracking Accuracy	Typically <0.1dB RMS signal degradation after tracking for
	30minutes (with tracking signal).
Prediction Accuracy	Typically <0.1dB RMS signal degradation over 72hrs (after
	loss of tracking signal).
Tracking Signal	May be derived from an external tracking receiver or from the
	(optional) Integral Beacon Receiver (IBR-L).
External	DC voltage varying directly with received signal strength
	(in dB). Scale factors between 0.1V/dB and 1.0V/dB can be
	preset with up to ± 10V offset.
Internal	Internal IBR-L requires an L-band signal with a level in the
	range -80dBm to -45dBm and C/No >40dB. Stability better
	than ± 150KHz. The received frequency is selected from the
	INTRAC front panel.
	The signal voltage and lock lost indicators are generated
	internally.
Antenna Position Encoders	Single resolver units. Operating frequency is 800Hz nominal.
Az & El	The INTRAC-305 is designed to operate directly with
	standard Andrew resolvers. Antennas used with the APC300
	controller, for which the INTRAC-305 is a replacement, are
	normally fitted with x2 resolvers. The part numbers of the two
	(alternative manufacturers) 2x resolvers known to have been
	used by Andrew are:
	Harowe 11BRCX-310-M-85V
	Clifton 11-BHM-19F/F776
	The INTRAC-305 can be configured (by the user in “Fitted
	Options”) to operate with the lower resolution (x1) resolver
	that may be fitted to antennas intended for APC100 control.
	The part numbers of the two (alternative manufacturers) 1x
	resolvers known to have been used by Andrew are:
	Harrowe 11_BRCX-310-R-85V
	Clifton 11-BHW-46TK/F561 or F817
Pol	The standard version of the INTRAC-305 is firmware
	configured for x1 resolvers. Firmware to enable the use of a
	x2 resolver for can be provided on request.
