Azimuth Family AZ420 Telcom Satellite Modem
The Newtec Azimuth Series AZ420 is a state-of-the-art satellite modem designed for fixed rate telco,
voice and data applications over satellite in full compliance with the DVB standards.
The AZ420 connects directly with terrestrial data and voice
networks through a standard G.703 interface.
In its default configuration, the AZ420 supports E1 rates.
The support of E2, T2, E3 and T3/DS3 rates are available as
It is also possible to configure the modem with a secondary
G.703 input/output, for the implementation of a redundant
configuration or to allow the modem to be compatible with two
different transmission rates.
AZ420 Rear Panel
At the output of the modulator, the signal is available on an
L-band interface. Extended L-Band, IF band as well as HPA control
functions are available as confi guration options. When activated,
the unique linear and non- linear predistortion option Equalink™
provides an additional link margin improvement of up to 2,5dB.
On the receive side, the AZ420 has a dual L-band input( 950-
2150 MHz). The active L-Band 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). An adaptive equalizer compensates linear distortion of
the transmission channel and 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 fi nd the optimum input back-off setting
very easily for 16APSK or 32APSK operation, whether or not nonlinear
predistortion is applied .
