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, zero 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

Additional Information

Scalable

The DxV changes the rules of the design through to production test flow. It provides both the flexibility and compact size to be used in offices or small benchtop lab situations but with high performance, high density instrumentation to deliver real ATE performance in high volume production test environments.

Can be Used as a Validation Tool or for Initial Production

The DxV uses the same proven architecture as the successful Diamondx and with its ultra-compact footprint and links to other design validation tools, can be easily used to meet the needs of silicon validation and initial production stages. With these links to approved 3rd party software tools for silicon validation and 3rd party hardware instrumentation, the DxV is the ideal pre-production engineering test system.

Smallest Footprint for a High Performance SOC Test System

The test system is a self-contained unit with an embedded high-performance Linux controller running Cohu’s Unison test environment and associated tools. The ‘single box’ design and low overall weight enables true zero footprint test floor impact when docked to probe or final test material handlers.

Typically, less than 50 lbs for the basic system, with air cooling and single-phase low power supply requirements of 200-240 V, the Cost of Ownership economics with respect to facilities costs are significantly reduced compared to traditional high performance ATE.

Part of the Diamondx Family

The DxV has five high throughput Diamondx compatible slots allowing configuration of a range of Diamondx instrumentation, digital options spanning high density 192 channel general purpose full featured digital pins to memory port and high-speed serial of 6.4 Gbps.

DC and mixed signal instrumentation include 72 channel VI solutions and 24 bit converter options.

The DxV is a full featured ATE in a desktop size which delivers flexibility and enables use limited only by imagination.
