Abstract :
This paper presents a flexible and adaptable instrument for generating DVB-S2 signals for multi-level testing and performance analysis of satellite receivers. The instrument is based on a high level system model that describes and implements the processing chain of the DVB-S2 transmission system and GEO satellite channel impairments insertion mechanisms, while it utilizes high-speed and high resolution DACs for output signals generation. With the contribution of such a setup, numerous validation and verification tests, under real conditions, can be performed on prototype implementations and realization development stages of emerging DVB-S2 satellite receivers
