Please note: Updated beacon receiver models and related information is found at this Radeus Labs web page.
The Model BR23-L, version 4 firmware, offers the full L-band range of 930 to 2300 MHz, digital level reference setting, and 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.
- Wide bandwidth, 930 – 2300 MHz standard
- Digital level reference setting, -40 – -100 dBm on 0.5 dB steps
- 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.
