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 ...

Logic analyzer probing can be classified into two groups. The first group consists of the signals that were “designed in.” This means that signals that are to be observed were intentionally routed to ...

As I mentioned in my recent columns on the topic of adding pull-up or pull-down resistors to the inputs of unused or partially used logic gates and functions (see Part 1, Part 2, and Part 3), I was ...

Test-and-measurement vendor Agilent Technologies (Palo Alto, Calif.) now has a logic analysis probe for folks designing-in Intel Pentium 4 microprocessors in 775-land packages. Agilent's new E8045B ...

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 ...

Mark Henderson of Long Beach, CA has started a “Kickstarter” program for a debug tool that he says, “will be the first tool you’ll use when chasing issues in your electronic product”. He calls it “tiq ...

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 ...
