[Nicholas Murray]’s Composite Test Pattern Generator is a beautifully-made, palm-sized tool that uses an ESP32-based development board to output different test patterns in PAL/NTSC. If one is checking ...

Scan testing has been the foundation of digital-device production test for many years. Several innovations have been developed to keep up with the growth in pattern-set sizes brought about by large ...

CRTs don’t last forever, and neither do the electronics that drive them. When you have a screen starting to go wonky, then you need a way to troubleshoot which is at fault. A great tool for that is a ...

Test patterns play critical roles in physical layer compliance testing by challenging different aspects of a system. Receivers in HSS (high-speed serial) technology must be stable. When the average ...

Test compression sounds like magic. Read on to learn how this trick is done. Large, complex ICs are viable because their design meets test as well as functional requirements. Design for test (DFT) was ...

Testing digital designs usually requires one or more digital signals, some of which can be very difficult to generate. Pattern generators are specifically designed to address this problem. Whatever ...
