Product Information 

The UI-192A series of digital modules for the VXIbus provides the basis for a complete state-of-the-art digital solution at the subsystem level. The UI-192A is the solution for both legacy digital replacement and new test stations to be built for digital test including aircraft/avionics, weapons systems, spacecraft, semiconductors and medical devices. 

We exploit the VXI 3.0 and 4.0 platforms to produce highly-capable and reliable digital subsystems that are backed by our proprietary digital sequencer architecture. 

The UI-192A has been designed using Field Programmable Gate Arrays (FPGA) and pin-driver technologies plus an advanced sequencer, providing a choice of fixed or variable driver/receiver personality modules to create flexible digital instrumentation. 

Bus-Emulation Meets Stimulus/

Response

For years, the test engineer faced less than

desirable alternatives when selecting a

digital resource. Early digital products were

basic stimulus/response architectures,

were expensive, consumed abundant 

realestate,and were power-hungry. They also

required extensive programming to emulate

a relatively simple digital interface.

For many applications, these bus emulation

products significantly reduced cost, realestate,

power, and programming requirements.

However, the another question for the test 

engineer: Does the test system require bus 

emulation or a traditional stimulus/response

 digital resource?

The United Instruments™ UI-192A solves

this dilemma by integrating both bus-emulation

and stimulus/response architectures

into a single resource for the VXIbus.

Advanced Features for Modern Digital Test Development 

The UI-192A’s innovative design is suitable for today’s challenging digital test system applications. The flexible FPGA design enables the 192A to meet special user and legacy requirements. The high-speed data sequencer provides control over test patterns, timing, and format.
