A novel open Automatic Test System based on SI and SCMM technology

Aiming at effectively addressing the dedicated testing application issues of special-purpose communication devices, this paper devotes to some research on integrated stimulating, analyzing and testing technologies for electronic communication systems and the signals to or from the systems. An open ATS (Automatic Test System) architecture based on related technologies as SI (Synthetic Instruments) and SCMM (Single Connection Multiple Measurement) is proposed firstly, and the system structure is studied. Several practical test applications are then introduced to prove that given a uniform system platform, a variety of test functions, such as stimulating signals generation, test procedures control and analysis, can be achieved by various system configurations; and the purpose of integrated testing and verification for terminals in communication and navigation systems should be attained consequently.
