If you want to measure voltage you reach for a voltmeter. Current? An ammeter. Resistance? An ohmmeter. But what about measuring AC power? A watt meter? Usually. But if you know what to do, you could ...

Digital oscilloscopes are the norm in most engineering labs, but the chances are that you have not fully explored their features. Among the more interesting features of a digital oscilloscope is the ...

Recently, an EDN reader asked “Why do oscilloscope manufacturers put amplifiers on their probe tips rather than in the oscilloscope?” Placing the amplifier in the probe minimizes signal losses in the ...

The inductor is an often forgotten passive electrical elements used to design analog circuitry. [Charles’s] latest proof of concept demonstrates how to measure inductance with an oscilloscope, with ...
