Product
VXI Series
-
The first VXIbus specification was introduced to the test and measurement community in 1987 and was initially developed to provide a card-based instrumentation platform for applications that required high density and high performance. The platform continues to thrive today by leveraging off the original specifications which define the necessary physical (real estate/cooling) and electrical standards for demanding applications and has established itself as the ‘time-tested bus you can trust’ for requirements that must be supported in excess of ten-fifteen years.

9025 VXI - 25 Module Solution for VXI
-
The 9025 VXI Receiver is a 25-module solution designed for use with VPC pre-wired interconnect adapters, but can also accommodate a combination of pre-wired interconnect adapters and discrete-wired modules using retainer blocks.1-4 modules attach to an interconnect adapter which in turn is attached to the VXI card. This connector “funnel” forms a complete VXI module, which is easily inserted or removed from the VXI mainframe for maximum flexibility in testing applications. The interconnect adapter also provides room for driver sensors. External cabling to the card is done with a cable clamp or connector located on the top or bottom of the adapter. The positioning of funnels and use of discrete wiring modules can affect the performance of the product. Please contact us for technical assistance.

VXI Analog Instrument
Ai-710
-
The Ai-710 is a Core System Instrument (CSi)—a single-slot, multi-function VXI analog test instrument. It eliminates the requirement for multiple discrete instruments that often provide inadequate test coverage for newer Units Under Test (UUTs). The single-slot VXI form factor reduces tester footprint, as well.

VXI Backplanes
-
VXI is a prime example of the old saying, “if it isn’t broken, don’t fix it.” Since the late 1980’s, VXI has been a trusted standard in the world of testing solutions as a more compact and robust predecessor of the GPIB standard. Arising initially to soothe the need for a more compact and integral open testing standard, VXI is still as necessary and impactful as it was more than 30 years ago.
