Beacon Tracking ReceiverModels 3434-CH
C-Band Beacon Tracking Receivers
Version 4

A tracking receiver for antenna step tracking and automatic uplink power control

The Model 3434-CH Version 4 is the latest release of our reliable series of 3434 Beacon Receivers. With Version 4 firmware the Model 3434-CH has an input of 3.4 – 4.2 GHz****, Digital Level reference setting, Ethernet connectivity with M&C control interface, and power up temperature compensation for rapid signal acquisition. The 3434 series now offers our proprietary Accu-trac search and acquire AFC feature with several search bandwidths up to ±800 kHz. Frequency selection on 10 kHz steps may be accomplished from the front panel or via remote control. Pre detection noise bandwidth of 50 kHz (or factory option of 25 kHz) facilitates accurate tracking at very low C/N levels for use with either CW or BPSK carriers.

  1. AFC disable option for wide data carrier applications
  2. Digital level reference setting, -30 to -90 dBm on 0.5 dB steps
  3. Accu-trac signal tracking feature for high drift LNB applications with selectable acquisition bandwidths up to ±800 kHz
  4. RS-232/422/485 and Ethernet, control interface, all Standard / Front panel selectable
  5. Dual signal strength output / 2 identical analog outputs for simultaneous antenna tracking and UPC control

The output of the Beacon Receiver is a DC voltage proportional to the input signal level to facilitate both antenna 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 an external Loss of Carrier Alarm. A front panel VFD or SSC GUI (via your computer) displays operating frequency, relative signal level, carrier lock or alarm, and input level.

Satellite Systems announces the new control GUI version 2.0 for our Beacon Receiver Product line. Enhanced control features and additional monitoring tools are included along with strip charting for signal strength, AFC, and temperature. Version 2.0 also includes a new event-triggered alarm feature that allows for email notification to your laptop or cell phone. Alarms are triggered via signal strength, loss of signal, and AFC conditions.
