Measuring AC current (220-V mains RMS current) is not as simple as measuring DC current. In DC current measurement, you can simply hook the oscilloscope probe to the shunt resistor and calculate the ...

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 ...

For anyone designing DC-DC converters, AC-DC power supplies, or the system around it, understanding the power supply’s operation under both the best and worst conditions is important. The load of the ...

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 ...
