D.1 DESCRIPTION
The M4DBDA8 is a stand-alone bi-directional & multi-channel Signal
Conditioner that performs on-channel processing (narrowband filtering,
automatic gain control and output level control) on the received signals and
provides a composite equalized multi-channel signal suitable to drive its
internal high-power amplifiers that feed the RF Tx Output signals.
The core Digital Signals Processor (DSP) board uses state-of-art reconfigurable
logic to perform digital signal processing (channelization) thanks to its high-
speed parallel hardware, high speed/performance Analog-to-Digital
Converters (ADCs) and Digital-to-Analog Converters (DACs) to interface with
the analog (Radio Frequency) world. Advanced digital filtering techniques
deliver low group delay and excellent phase linearity to support current
analog transmissions as well as new digital encoding systems.
High-linearity/low-noise analog interface hardware provides pass-band
filtering and gain stages to perform proper signal conditioning to interface
with the DSP digital core sub-system.
Discrete Digital I/O alarms are available for external monitoring.
A built-in Web Server provides a Graphical User Interface (GUI) to ease in
remote monitoring & control. Access is obtained via a PC’s Web Browser
and a TCP/IP connection to the Unit.
