What do a Rogowski coil, a magnetic core, and a hall effect sensor have in common? They are all ways you can make oscilloscope probes that measure current. If you think of a scope as a voltage ...

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 ...

If you want to measure AC or DC current with an oscilloscope, a current clamp is a great way to do it. The clamp surrounds the wire, so you don’t need to break the connection to take your measurements ...

An oscilloscope and a device under test (DUT) constitute a de-facto system. In it, the most overlooked element is the interface between the two: the oscilloscope’s probes. Test personnel simply grab ...

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 ...
