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 ...

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 ...

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 ...

[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 ...

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 ...

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 ...

The MSO5022 25-MHz, two-channel benchtop mixed-signal oscilloscope with an eight-bit resolution also packs a 16- channel logic analyzer. Features include a USB connection, 7.8" 640 x 480 color LCD, ...
