Featuring vectorless test technology, U9403A Mini In-Circuit Tester (ICT) provides unmuxed per-pin programmable digital test architecture suitable for manufacturers testing low-access devices. Support for industry-standard Standard Commands for Programmable Instruments (SCPI) enables instrument to run true scalable parallel testing (synchronous or asynchronous) and simplifies addition of in-circuit test, component level testing, and diagnostics capabilities into functional test programs.
