The third generation ATS emphasizes the puter for central equipment, based on standard bus techniqueto connect external instruments/equipments. This paper discusses the advantages of USB bus to construct ATS, according to the theorems of USB bus and ATS. Issues and solutions in the procedure of ATS constructing also put forward in the paper.Keywords: ATS, USB bus, Virtual instrument6
