1.3.5 Outputs
Three ASI-C (copper) outputs supplying a DVB and ATSC
18
MPEG-2
transport stream are supplied as standard.
1.3.6 IF Modulation
E5714
The internal satellite modulator within the E5714 supports QPSK
modulation in accordance with EN 300 421 (DVB-S). It provides a main
and monitoring IF Output. The IF frequency can be tuned between 50 MHz
and 90 MHz in steps of 125 kHz. The maximum symbol rate is 30 Msym/s
60 MHz to 80 MHz (20 Msym/s at 50 MHz and 90 MHz).
E5740
The satellite modulator fitted within the E5740 is capable of QPSK
modulation in accordance with EN 300 421 (DVB-S), and is also capable of
8PSK and 16QAM modulation in accordance with EN 301 210 (DVB-DSNG).
It is available with either IF outputs, or L-band outputs.
The IF output frequency can be tuned between 50 MHz and 180 MHz in
1 kHz steps. The L-band output frequency can be tuned between 950 MHz
and 1750 MHz in 1 kHz steps. The maximum symbol rate is 48 Msym/s.
E5715/E5750
The OFDM modulator fitted within the E5715 and E5750 provides an IF
output at 70 MHz and 0dBm. It is capable of operating in 2k carriers, or 8k
carriers transmission modes. It supports FEC rates of ½,

1.3.7 Control and Monitoring
Remote control of the Encoder is via the Ethernet network running the
Simple Network Management Protocol (SNMP) protocol or via the
RS-232/RS-485 remote control port.
Alternatively, Local control is implemented through the front panel keypad
and display.
1.3.8 Options and Upgrades
