[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 ...

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 ...

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 ...

If you do any work with high-speed signals, you quickly realize that probing is an art unto itself. Just having a fast oscilloscope isn’t enough; you’ve got to have probes fast enough to handle the ...

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 ...

In Part 1, we covered the bandwidth limitations of passive probes and why they can't be used in today's switching power supply designs. High-frequency probes are expensive and often out of reach to ...
