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

The AZ120 interfaces directly with terrestrial data and voice networks through a standard G.703 interface.

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

At the output of the modulator, the signal is available on an L-band interface. IF- and RF-band as well as DC power supply and reference frequency are available as configuration options, providing a compact and cost effective solution.

This modulator is fully compliant with the DVB-S and DVB-S2 standards and provides exceptional performance and bandwidth efficiency. When activated, the unique linear and non- linear pre distortion option Equalink™ provides an additional link margin improvement of up to 2,5dB, truly unleashing the full efficiency of higher modulation schemes such as 16 and 32 APSK.
