14 Tektronix to VXI Technology Cross-Ref. Guide
In addition to the abovementioned cross-referenced products, other obsolete Tektronix VXI
products are also provided for with functionally similar VTI products (Table 1-2). These products
do not come with cross-reference documentation or translation drivers, but can be provided upon
request.

TABLE 1-2: CROSS-REFERENCE TABLE OF INSTRUMENTATION
There are two main aspects associated with replacing obsolete instruments or switching systems:
Hardware Interfacing and Software Programming.
The issues associated with the hardware interface concern the cabling/wiring from the
switch/instrument to the interface adapter that connects the unit under test (UUT). Our cross-
referenced products come with Excel spreadsheets and documentation that provide a pin-for-pin
map between the obsolete Tektronix module and its equivalent replacement. VXI Technology also
provides complete cable assemblies/subsystems for our instruments/switches under one part
number, completely eliminating any internal engineering.
Minimizing the impact to existing application software becomes more difficult. Our cross-
referenced products come with translation drivers 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 (Figure 1-1). These drivers are
provided with all source code so that users can modify or code additional functions.
