The logic probe is powered from the device under test (DUT)—it may be any binary logic, which can be powered in the range +2 V to +6 V. This may be a microcontroller or 74/54 series logic chips, ...

A recent Design Idea in EDN magazine, “Logic Probe Uses Six Transistors” caught my eye because I had just pulled out an old logic probe purchased many years ago. It seems logic probes have fallen into ...

[Robert Morrison] had an ancient HP 545A logic probe, which was great for debugging SMT projects. The only problem was that being 45 years old, it wasn’t quite up to scratch when it came to debugging ...

We live in a day when it is very inexpensive to buy an oscilloscope, especially one with modest performance that hooks to a laptop. However, there was a time when even a surplus scope was out of reach ...

Test probes go a long way toward ensuring accurate, repeatable test results. Here's a look at how both active and passive test probes are evolving to match today's broadening oscilloscope bandwidths.

This file type includes high resolution graphics and schematics. The logic analyzer is a versatile tool that can help engineers with digital hardware debug, design verification, and embedded software ...
