User Manual for AZ430 WAN Satellite Modem
1 INTRODUCTION
1.1 Short
Description
The AZ430 is a state-of-the-art satellite modem designed for applications where
two parts of a Wide Area Network (WAN) are connected over satellite using routers
with HSSI interfaces.
The AZ430 interfaces directly with terrestrial routers through an HSSI interface with
bit rates up to 52 Mbit/s (standard HSSI) or 110 Mbit/s (extended HSSI).
This modem is fully compatible with DVB-S and DVB-S2 standards and provides
exceptional performance and bandwidth efficiency.
At the output of the modulator, the signal is available on an L-band interface. 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 AZ430 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. An
adaptive equalizer compensates linear distortion of the transmission channel.
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 .
