Beacon Receivers Model 3430-KuA — KuA sub-band Beacon Receiver

Beacon Tracking Receiver

Tracking receiver for antenna step-tracking and automatic uplink power control.

The Model 3430-KuA, Version 4, features an input of 11.7 – 12.2 GHz, Digital Level reference setting, Ethernet connectivity with M&C control interface, and power-up temperature compensation for rapid signal acquisition. 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. Digital level reference setting, -40 to -100 dBm on 0.5 dB steps
  2. Ethernet connectivity with M&C control interface
  3. Version 2.0 M&C control interface for remote monitoring from one, or multiple, locations
  4. RS-232/422/485 and Ethernet All Standard
  5. Temperature stabilization compensation.

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.

SSC’s control GUI version 2.0 for our beacon receivers provides enhanced control features and additional monitoring tools, along with strip-charting for signal strength, AFC, and temperature. Version 2.0 also includes an event-triggered alarm feature that can send email notifications to your laptop or mobile device. Alarms can be triggered via signal strength, loss of signal, and AFC conditions.
