The Newtec Elevation Series EL470 is a state-of-the-art satellite modem designed for the
transmission and reception of IP streams over satellite at rates
of up to 133 Mbit/s in full compliance with the DVB standards. The EL470 modem connects directly
to terrestrial IP network infrastructures via a single auto-switching Gigabit Ethernet interface
The EL470 comes with several hardware and software options
and can be used in Point-to-Point links as well as in Point-to-
Multi Point networks. It is compatible with a wide range of
encapsulation protocols: data piping, MPE, ULE and Newtec’s
XPE (Extended Performance Encapsulation).
The EL470 is capable of receiving DVB-S2 Multistream and VCM
signals and can optionally transmit in VCM mode.
For maximum bandwidth efficiency an ease of operation, the
EL470 has an embedded point-to-point FlexACM controller
option that allows to automatically and dynamically adapt its
uplink modulation parameters in function of the link condition.
The FlexACM client option provides the modulator/modem
on the other side of the satellite link with feedback on the
conditions of the received signal. When two modems both
equipped with the FlexACM controller and client options are
connected to each other, they negotiate automatically and
dynamically their configuration parameters in both directions.
At the output of the modulator, the signal is available on an L-band interface. IF-band as well as
BUC power supply and reference frequency are available as configuration options, providing a compact and cost effective solution.
The EL470 has a dual L-band input (950-2150 MHz). The active input is selected by the user and can
provide DC power and frequency band selection signals compatible with most professional and commercial
LNBs. Optionally, one L-band input can be replaced by an IF (50-180 MHz) input.
The integrated Noise & Distortion Estimator (NoDE) tool provides an accurate reading of the
satellite link margin even in presence of non-linear distortion and allows the user to find the optimum
input back-off setting very easily for 16APSK or 32APSK operation, whether or not non-linear predistortion is applied .
