For some oscilloscope applications, you need to measure a large dynamic range of values, and at the same time you need fine resolution to measure small changes in a parameter. For example, you can use ...

Oscilloscope technology has evolved from electromechanical assistance for hand-plotting to the development of full-featured ...

Things you can do with an oscilloscope. Some measurements, like “peak to peak amplitude” are pretty straightforward. But when should you use “mean” and when should you use “RMS”? What exactly is RMS, ...

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 ...

This video shows how to use the FFT function of RIGOL oscilloscopes. The FFT function allows the user to measure the frequency and time domain of the signal waveform, at the same time. In this ...

Don’t get zapped when buying a new high-voltage DC power supply. Understand the specifications first. Lasers, linear accelera-tors, X-ray machines, defibrillators, radar, and numerous other ...
