    AMT30 DVB-S/S2 High Speed Broadcast Modem

    The AMT30 modem series provide unparalleled flexibility in interfaces and capabilities stemming from its modular construction. The AMT supports two modulator/demodulator stuffing slots allow the AMT3  modem series to support the following configurations: TX Only, RX Only , TX and RX Modem , 1TX-2 RX , 1TX-4RX (AMT34).  The modem modulates carriers directly at L-band, resulting in an efficient uplink system with an extremely pure output spectrum. A 70±18MHz / 140±36MHz option is also available. The modem includes support for BPSK, QPSK, 8PSK and 16QAM with data rates from 16 kbps to 10 Mbps in 1 bps steps. The AMT30 provides Viterbi forward error correction (FEC) as standard. Available options include Intelsat compliant Reed Solomon outer FEC codec, or Turbo FEC option that greatly improves BER performance.Monitor and Control (M&C) is available via RS-232 and RS-485 ports to provide access to a command line interface, with an ethernet option for SNMP and Telnet interfaces. In addition, the modem can be configured via an optional front panel or hand held controller. DC power and high stability 10 MHz reference can be supplied for powering and synchronizing a Block Up Converter (BUC) and Low Noise Block Down Converter (LNB). As standard data interface the AMT30 modem provides a 10/100BaseT Ethernet supporting forwarding rates of up to 10Mbps for bridging or IP routing applications. In the AMT34 configuration, the AMT34 forwarding rate is limited to 10Mbps. Alternatively,

    The AMT30 can be ordered with EIA530 serial port interface capable of supporting 10Mbps speeds. In the AMT34 configuration, each of the four EIA530s is capable of supporting 10Mbps. In addition, PowerTrack™ system provides additional stability (control) over the transmission chain when using compatible AMT BUC’s. AMT BUCs include a power detector on the output, which the modem monitors and adjust its own Tx output level in response and maintaining a constant output power from the BUC. This closed loop power control maintains the output power from the BUC stable within ±1 dB under all environmental conditions.
