Model 3430-I I-Band Beacon Tracking Receiver
A tracking receiver for antenna step tracking and automatic uplink power control

The Model 3430-I is a fully frequency agile satellite receiver designed to provide a linear DC reference voltage proportional to the received signal level of a satellite beacon or narrow-band SCPC carrier. Frequency selection on 10 kHz steps may be accomplished from the front panel or remote control. Pre-detection noise bandwidth of 50 kHz facilitates accurate tracking at very low C/N levels.

Version 3 Firmware Features:

RS-232 / RS-485 are both included and selected via front panel menu options. Available baud rates of 1200, 2400, 4800, 9600 and 19200 are selected via front panel menu options. Extended RS-485 addressing range of hexadecimal 01 - FF. Remote Port polling active in Local Mode.

The output of the Beacon Receiver is a DC voltage proportional to the input signal level to facilitate both tracking control and automatic power control. A Loss of Carrier indicator is provided in the event the tracking signal is lost. Form "C" relay contacts provide external Loss of Carrier Alarm. A front panel VFD displays operating frequency, relative signal level, carrier lock or alarm and input level.
