Beacon Receivers
PRODUCT DATASHEET
LBR-2195A
The LBR-2195A is a satellite beacon receiver that provides DC output voltage proportionate to the input RF signal level over L-Band. The receiver will remain locked on the CW carrier signal and provide the DC output voltage relative to input RF level at the tuned center frequency. The LBR-2195A can also lock on and track BPSK type modulated carriers signals with excellent
performance. Typical time-to-lock period is <3 seconds. The LBR-2195A has been designed with the systems integrator in mind for satellite antenna and uplink power controller systems. The small form-factor is ideal for low-profile and restricted spaces.

Avcom Text-based API
Version 5.1
The text-based API allows users to interface using simple text commands. These commands are supported over USB, RS232, and RS422. Users can read and write settings over a terminal or integrate the commands into their system.
Supported Products
- LBR-2195A
- BR-MOD-1-9-B
- SA-MOD-1-9-B
The text-based API is recommended for beacon receiver applications that need a simple status output and may not be able to use Ethernet and/or TCP sockets. For details on the output options and a list of the available commands, please download and read the following user guide:
To include it in your application please download the zip file and include the aov_text_cmds.h. This file has a macro definition of all the commands to make integration easier.
