Board Debug

This is a video of the XJAnalyser Board bring-up and debug tool. This tool is great for getting access to signals that are not available through test points by using JTAG to access the pins. XJAnalyser can be used for both board Bring up to help engineers debug initial prototype hardware and verify proper assembly […]

Prototype Circuit Board

Prototype Printed Circuit Boards are early versions of electronic circuits. The first revisions of these boards usually have errors and require debug and test. Electronic product manufacturers (OEMs) typically send the files produced by their schematic capture package to a circuit board FAB or Prototype house for to be built. Often so-called quick turn PCB […]
