Download this article in PDF format. An oscilloscope is used to measure the voltage change of a signal over time. After a digital multimeter, an oscilloscope is typically the second most common piece ...

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 ...

Signal integrity is the primary measure of signal quality. Its importance increases with higher signal speed, oscilloscope bandwidth, the need to view small signals, or the need to see small changes ...

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 ...

Oscilloscopes often include the ability to cross plot the data from two waveforms using X-Y displays. These displays find applications in switched-mode power measurements, baseband ...

Today's digital designs often find significant portions of their functionality implemented with FPGAs. When debugging such systems, one challenge can be gaining the necessary visibility to key signals ...
