Tracking receiver for antenna step-tracking and automatic uplink power control.
The Model 3434-CH, Version 4, 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 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.
- AFC disable option for wide data carrier applications
- Digital level reference setting, -30 to -90 dBm on 0.5 dB steps
- Accu-trac signal-tracking feature for high-drift LNB applications with selectable acquisition bandwidths up to ±800 kHz
- RS-232/422/485 and Ethernet, control interface, all Standard / Front panel selectable
- Dual signal strength output, two 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.

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 by signal strength, loss of signal, and AFC conditions.
