SAMS is a product family in the area of antenna radiation pattern acquisition and processing. It has been developed and is commercialised since 1998, by SILICOM, in partnership with the CNES (French Spatial Agency). The CNES expertise in antenna measurements together with SILICOM's proficiency in software development and in hyper-frequency studies led to producing a modern, reliable and user adapted software system, both in its user modes and in its parameter setting, maintainability, speed and measurement accuracy. Beyond the innovation included in this system, we can firstly promote, the automatic measurement and calculation speed in order to optimise the velocity/precision compromise, but also a separated data analysis module that allows one to compare data issued from any simulation code and from experiment. The article presents the characteristics and the technical innovations of this system.
