Pickering VXI to PXI Cross Reference

VME eXtensions for Instrumentation (VXI) is an open standard platform for automated test based on the modular VME computer bus. Introduced in 1987, this modular chassis-based architecture reduced the size and increased the performance of high-end test systems. VXI systems provided higher data transfer rates and real-time performance not possible with rack-and stack systems, and were principally successful in the military and aerospace markets. However, VXI is now over 30 years old and many of the leading T&M companies are now no longer supporting the standard.

More test systems designers are choosing the PCI eXtensions for Instrumentation (PXI) platform when designing new modular test systems or replacing or updating existing test systems such as VXI. Originally introduced in 1997, PXI is an open T&M standard now supported by almost 70 companies working under the umbrella of the PXI Systems Alliance (PXISA), which publishes the PXI specification and ensures instrumentation interoperability. Pickering Interfaces is one of six current Board level members of the PXISA.

Features:

• Better Availability of PXI
• Hardware costs are lower for PXI
• PXI throughput at peak bandwidth of 132 MB/s
• PXI modules are significantly smaller in footprint
