Unidec

This is a DEC, DCJ11 processor bus emulation system built in DOS/Borland Pascal that allows in circuit and functional test the entire processor system (memory, boot EPROMS, QSLU, LTC, DRV11 parallel I/O, machine I/O and jumper settings by removing the DCJ11 processor and plugging in our 60 pin emulation pod. I designed and wrote this software in 1996 for my BSEE undergrad sr. project . We fired this up today in order to test a legacy board. 

Here’s an example of legacy support, 35 years of support for this UIC Seq Tst Expanded Range Verifier (ERV) since 1989

Testing a three phase brushless, variable reluctance motor (VRM) driver 🤓. Checking for phase shift,  and pulse width modulation (PWM).

Our Tacit ES system leverages ICT vector capture and compare heuristics to find subtle circuit failures other ICT equipment often miss,

This proprietary Tacit-ES technology is similar to today’s antivirus software that looks for patterns of data (heuristics) that are correct and incorrect during a board’s function. Then, the combination of knowledge base information and expert knowledge learned in the process helps determine which device is causing a functional test to fail.

This proprietary technology is designed to take the guesswork out of circuit board test and troubleshooting. The technology also improves quality and dramatically reduces the likelihood of faulty circuit boards from being put back into service.

Functional testing is crucial to ensuring your equipment will work when put into use. We develop tests that verify function, confirm electrical signals and check calibration.

Testing of a 3 phase 240 VAC input regulated 350 VDC high current supply. We find this electrifying, do you? 😁

Repairs start with good workmanship.
