[IMSAI Guy] wants you to build a non-contact scope probe. The cost? Assuming you have a bit of wire and a regular scope probe, it won’t cost you anything. Why do you want such a thing? You can see ...

The oscilloscope is probably the most versatile piece of test equipment you can have on your electronics bench, offering a multitude of possibilities for measuring timing, frequency and voltage as ...

This file type includes high-resolution graphics and schematics when applicable. Literally hundreds of different oscilloscope probes are available (Fig. 1), so how do you choose the right one? There’s ...

Dedicated differential probes are carefully designed with matched inputs, shielding, and circuitry that reject common-mode noise and interference. In contrast, the A–B math method relies on two ...

Just about everyone who has ever operated an oscilloscope has used an oscilloscope probe at one time or another. Some have had good experiences, while other had unfavorable ones— possibly as a result ...

Modern power supplies are edging upward in operational frequency. The benefits include a reduction in size and weight, plus an increase in energy density. For these designs, engineers are migrating to ...
