Abstract

This article describes a diagnostic current sourcing and sinking meter for testing digital electronic cards and boards. It allows easy diagnosing of errors on common bus structured networks and printed circuit lands (NET) which are often found in active digital electronic cards, boards and systems. It provides accurate determination of bus/NET problems, saves considerable time over other methods, and reduces the number of cards that have to be scrapped. Having a meter that tells a tester, engineer or technician which node or element on a bus/NET is sinking or sourcing the current is often necessary when trying to determine why that bus/NET is not functioning properly at a certain point in time.
