ABex `System Architecture`

The ABex expansion enables fully wireless distribution of analog and digital measurement and power signals throughout the entire system. Signals are routed via defined lines with stable impedances. No cables have to be used to connect the DUT with the switching matrices and the required PXI instruments.The system can be equipped with a dedicated DUT interface, based on high quality Virginia Panel technology. The interface guarantees 20,000 mating cycles.

Why should System Integrators use the ABex platform?

System integrators gain significant advantages when building custom test solutions with Abex

Streamlined Development Process
Dramatically reduced cabling requirements - Instead of complex point-to-point wiring, the analog bus and power bus handle connections through the backplane, minimizing manual cable routing
Faster system assembly times - The terminal module concept enables cable-free connections between system components, accelerating the build process
Enhanced signal integrity - Built-in analog bus provides superior signal quality compared to traditional cabling methods
Flexible Architecture Options
Modular design approach - Combine standard PXI chassis (up to 18 slots) with ABex enhancements or use integrated PXI backplanes
Application-specific customization - Create specialized instruments using the terminal module concept, such as pin electronics for semiconductor testing
Reduced troubleshooting - Fewer cable connections mean fewer potential failure points and easier system maintenance

What are the benefits or Operational Advantages for end users and final customers?

Final users, including EMS (Electronics Manufacturing Services) companies, experience multiple benefits.

Improved System Reliability
Reduced interference sources - Fewer cables mean fewer opportunities for signal degradation and electromagnetic interference
Enhanced signal quality - The analog bus provides superior signal routing compared to traditional cabling
Simplified maintenance - Fewer connection points reduce potential failure modes
Faster Time-to-Production
Quicker test system deployment - Reduced setup complexity accelerates implementation timelines
Streamlined reconfiguration - Systems can be modified more easily when production requirements change
