Beacon Receivers
EVO-RBR (Rev B)
The EVO-RBR is a satellite beacon receiver designed on a completely new platform to meet today’s
system challenges. This robust product features many capabilities to provide reliable operation and
monitoring in rackmount applications.
A CW satellite beacon carrier can be acquired quickly and tracked in On-the-Move, as well as in
fixed-site applications. The receiver can lock on and track BPSK-type carrier signals and is uniquely
capable of locking on and tracking DVB-like carriers utilizing an exclusive Avcom-only Carrier- EdgePower-Tracking (CEPT) function. In addition, it provides a voltage output from 0 to 10 VDC
proportional with the input signal.
A unique feature of this beacon receiver is that when the beacon receiver function is not in use it
can be used as a full-function spectrum analyzer. This allows systems to track on a beacon and
monitor a carrier without the need for a separate device.
The beacon receiver can be connected via ethernet, USB, or serial, and supports communication
with a WEB-GUI, POSIX-C API, text-based API, and Avcom’ s EVO GUI. This wide range of options
makes the unit ideal for interfacing with large complex M&C systems or simple microprocessorbased systems.
