Newtec Azimuth Series AZ420 Telco Satellite Modem
DVB-S2 & DVB-DSNG, 50 Mbps IP processing capability
AZ420 Series Telco Satellite Modem
This product has reached end of life and has been replaced by the Newtec M6100.
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. This modem 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 configuration option. 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.
L-Band
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 configuration 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 Newtec 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 .
