VXI products have been in the marketplace since 1987, and many test systems that
were designed in those early years are still operational today. As with older GPIB
products, certain VXIbus products have run into component obsolescence problems.
Over the last ten years, VTI has provided functionally similar products to replace
such obsolete instruments, specializing in translation drivers, cross-reference
cable assemblies and other solutions to minimize the impact of re-engineering the
existing test station design.
System developers who standardized on Tektronix VXI products, or have ATE built
around them were faced with "ATE Obsolescence" issues when Tektronix terminated
their VXI line in 2001. Changing from these products to an alternate family of products
traditionally requires a large investment that would involve extensive rewriting
or translation of code, re-engineering of test adapters and re-verification of new
test programs.
VTI has years of demonstrated success allowing specific Tektronix products to be
replaced with functionally superior products that will be supported for at least
the next 10 - 15 years. This approach enables existing Tektronix VXI product users
to continue building systems with minimal engineering impact.
Cross-Referenced Products
Cross-referenced products come with translation driver source code (VISA required)
and connector cross-reference documentation, minimizing engineering efforts associated
with changing products.

Our cross-referenced products come with translation drivers and source code that
would replace the existing Tektronix drivers. These translation drivers map the
key VXIplug&play function calls to the obsolete Tektronix hardware
directly to our cross-referenced product.
Functionally Similar Products
In addition to cross-referenced products, VTI offers that are functionally similar
to their Tektronix equivalent.
