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 ...

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 ...

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 ...

Welcome to the Oscilloscope Triggering Advanced Course! In this series, I will walk you through the details of every corner of real-time oscilloscope trigger systems, and by the time we’re done, ...

AEMC Instruments has introduced a new accessory to its line of hand-held OX series oscilloscopes to facilitate measuring AC voltages in industrial applications where larger clips are required to clip ...
