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 ...

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 ...

Agilent Technologies has introduced the N4850A digital-acquisition probe and the N4860A digital stimulus probe, which support cross-domain measurements for the design, validation, and integration of 2 ...

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.

[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 ...
