Logic probes are used to analyze the logic states (high/true: logic 1 or low/false: logic 0) of digital signals. To verify and debug today ’s high-speed, low-voltage digital signals, you need logic ...

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, ...

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 ...

Semiconductor / High Density Fine point, spring loaded probes, which are usually mounted in a test jig. They are used to test semiconductor interconnects and high-density circuit boards. Coaxial A ...

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 ...

[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 ...

Why are test points a crucial element in developing a successful circuit? Types of test points available, and the different techniques that employ them. Electronic design has always been an endeavor ...

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 ...
