Newtec AZ920 Telco Satellite Demodulator

This product has reached end of life and has been replaced by the M6100.

The Newtec AZ920 is a state-of-the-art telco satellite demodulator designed for the reception of fixed-rate telecom voice and data applications over satellite in full compliance with the DVB standards. The 920 can be used in conjunction with the telco satellite modulator AZ120.

In its default configuration, the Newtec Azimuth Series AZ-920 supports E1 rates.  The support of E2, T2, E3 and T3 (DS3) rates are available as configuration option.  At the output of the demodulator, the signal is available on a G.703 interface.

It is also possible to configure the demodulator with a secondary G.703 output, for the implementation of a redundant configuration or to allow the demodulator to be compatible with two different transmission rates.

The AZ920 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.

This demodulator is fully compliant with the DVB-S and DVB-S2 standards and provides exceptional performance and bandwidth efficiency.

Equalization

The AZ 920 is equipped with an adaptive equalizer to compensates linear distortion of the transmission channel.  The integrated Noise & Distortion Estimator 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 non-linear pre-distortion is applied .
