Application

The AMT-34 provides BPSK, QPSK, 8PSK and 16QAM demodulation schemes andViterbi as the FEC as standard, individually on each demodulator. The addition of Reed Solomon and the New Turbo codec provide performance gains. TCP simultaneously offers increased coding gain, lower decoding delay and significant bandwidth savings. The rates span from 0.75 to 0.95 dependant on modulation type and are interoperable with market standard. 

Given the modular design the unit can be configured to offer L band Rx, 70MHz RX. It’s directly modulated L band transmit signal leads to an extremely pure spectrum resulting in efficient uplink systems, and the L band has a resolution of 100Hz.

In large installations, multi-drop RS485 M&C is used to control several AMT-34’s or you can use the Ethernet interface with Telnet or SNMP. A PC may be used to configure the unit and access all alarms and status messages. A front panel jack is provided on each unit for local hand-held terminal access. All other connections are located at the rear panel of the unit.

The data interface is RS422 signal levels via an independent RJ45 connector from each demodulator. Optionally, it can be equipped with an Ethernet 10BaseT IP Gateway interface providing a single connection for all traffic.

The L-Band input to each dual demodulator is via an F-type connector (standard). The 70 MHz input to each dual demodulator is via a BNC connector.
