Beacon Receivers BR23-L L-Band Beacon Receiver

Beacon Tracking ReceiverModel BR23-L
L-Band Beacon Tracking Receiver
Version 1


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

The Model BR23-L Version 4 is the latest release of our reliable series of Beacon Receivers. With Version 4 firmware we now offer the full L-band range of 930 to 2300 MHz, Digital Level reference setting, & M&C. 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.

  1. Wide bandwidth, 930 to 2300 MHz standard
  2. Digital level reference setting, -40 to -100 dBm on 0.5 dB steps
  3. RS-232/422/485 and Standard

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 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.
