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 ...

The E5394A soft-touch connectorless touch probes offer very low electrical loading for the company's logic analyzers. They require no adapter and reduce capacitive loading by 80% compared with other ...

Paired with the 16900A logic analysis system, the E8045B logic analysis probe promises extensive visibility into the Pentium 4 processor in the 775-land package. The probe interfaces the logic ...

Hackaday reader [JumperOne] was in need of a logic probe that he could use to reliably test some tiny .5mm pitch IC pins. The probe that came with his oscilloscope was a bit too big and not near sharp ...

When testing circuits with a logic probe, it is sometimes difficult to watch the LEDS on the probe to determine the logic state. With this probe the logic states are audible. This probe is designed ...
