Diamondx DxV Test System
Changes the Rules of Design Through to Production Test
The Diamondx 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 an office environment
- Energy-efficient, low power consumption
- Ideal for lab development and high-volume production
