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, ...

Measurement instruments mustnot affect the circuits they’remeasuring. A logic probe, for example,must correctly detect logic levels, and itmust place no undue loads on the testcircuit. The logic probe ...

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 ...

[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 ...

Test probes go a long way toward ensuring accurate, repeatable test results. Here's a look at how both active and passive test probes are evolving to match today's broadening oscilloscope bandwidths.

This file type includes high resolution graphics and schematics. The logic analyzer is a versatile tool that can help engineers with digital hardware debug, design verification, and embedded software ...
