Digital Test Equipment and Debug
Digital test equipment encompasses the specialized instruments and tools that engineers use to observe, capture, and analyze digital signals within electronic systems. Unlike analog measurements that deal with continuous voltage levels, digital testing focuses on logic states, timing relationships, and protocol-level communications that define how modern digital systems operate.
Effective debugging of digital systems requires understanding not only the theoretical behavior of logic circuits but also the practical realities of signal integrity, timing margins, and protocol compliance. From simple logic probes that indicate high and low states to sophisticated protocol analyzers that decode complex communication streams, these instruments form the essential toolkit for anyone developing, testing, or troubleshooting digital electronics.
