DxV Test System

Changes the Rules of Design Through to Production Test

The DxV provides full semiconductor ATE performance in a desktop PC footprint. Fully integrated, ultra-compact test system designed to be used in the engineering lab or office. Unlike traditional semiconductor ATE solutions that is no mainframe, separate workstation or support cabinets needed. The DxV is completely stand-alone, so it can be placed on a bench or desktop:

  • Ultra-compact, small footprint, light weight, single box design
  • Air cooled with low ambient noise for office environment
  • Energy efficient, low power consumption
  • Ideal for lab development and high-volume production
