I find it pretty annoying when I use a multimeter and look at the display only to find out that I accidently disconnected the probe from the pad.That's where the logic probe, we dubbed Beep, comes in.

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, ...

[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 ...

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 ...

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 ...

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 ...
