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 ...

Probing is critical to making quality oscilloscope measurements, and often the probe is the first link in the oscilloscope measurement chain. If probe performance is not adequate for your application, ...

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 ...

Wires and cables tend to behave as transmitting antennas. When troubleshooting a system for EMI, you must identify which cables have these undesirable “common mode” currents. Current probes let you ...

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...
