UEI has ported its sophisticated PowerDAQ family of data acquisition PCI bus cards to the CompactPCI/PXI form factor.


For instrumentation applications where you need advanced triggering and intercard data transfers, PDXI is the answer. You start with all the functionality of CPCI but add triggering from a CPU card to each I/O card, triggering among I/O cards and a secondary bus that allows high-speed transfers of data or control signals among adjacent slots.


PDXI (PowerDAQ eXtensions for Instruments) cards function perfectly in any C-sized CPCI/PXI slot. You can take the same applications programs from a desktop PC and run acquisition and control tasks without modification on a CPCI/PXI system.
