A recent Design Idea in EDN magazine, “Logic Probe Uses Six Transistors” caught my eye because I had just pulled out an old logic probe purchased many years ago. It seems logic probes have fallen into ...

This Design Idea describes a simpleyet powerful handheld probethat you can use as both a logic probe anda pulse generator either individually orsimultaneously. This feature makes theprobe useful for ...

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 ...

Logic probes are simple but handy tools that can be had for a couple of bucks. They may not be the sexiest pieces of test gear, nor the most versatile, but they have their place, and building your own ...

A non-intrusive device, the FS2009 PCI-X-2.0 protocol analysis probe captures signal activity at up to 266 Mtransfers/s (133-MHz clock). It supports PCI-X 1.0 and 2.0 Mode 1 and Mode 2 ...

It looks like something out of the Matrix or the Dune movie – imagine this electric needle plunging into your flesh and injecting you with the Snow Crash virus. Or something. In any case, it’s more ...

Timing relationships between signals are critical to reliable operation of digital designs. With synchronous designs, the timing of the clock signal relative to data signals is especially important.
