How to measure the time constant with an oscilloscope

Measuring the time constant with an oscilloscope is easy. Simply make a quick calculation and a cursor measurement. To measure the time constant of an RC circuit or an RL circuit with an oscilloscope, pick two reference points on an edge of your signal and see how long it takes to grow/decay 63.2%.

Time domain vs. frequency domain, what’s the difference?

In this episode of What the RF (WTRF), Nick goes into detail on the difference between the time domain and frequency domain and demonstrates both on an oscilloscope and signal analyser respectively.

What is a spectrum analyser and what measurements you can make?

Learn what a spectrum analyser is and the various measurements you can make with one. What is a spectrum analyser and what measurements can it make? A spectrum analyser displays received signals with respect to amplitude vs. frequency. This is called frequency domain analysis.

What is crosstalk and how to identify it with an oscilloscope?

What is crosstalk and why do I care about it? Crosstalk is interference on a signal from another signal. Any signal could interfere with another if a board layout is too crowded. Digital lines can disrupt power lines.

Fast fourier transforms with an oscilloscope

What is fast fourier transform and why do I care about it? If there is unwanted frequency content in your design, it could interfere with other components, cause excess noise, or even voltage spikes that can cause your device to malfunction.

What is oscilloscope segmented memory?

Traditionally on an oscilloscope when you capture a long span of data, you sacrifice measurement accuracy. Which means when you zoom back in on that signal, you can’t make accurate measurements because the signal is distorted.

How to perform frequency response analysis on an oscilloscope

In this episode of Scopes University, we will learn how to do Frequency Response Analysis, or FRA, on an oscilloscope. This Keysight exclusive application enables you to characterise your device using a Bode plot right on the screen of the oscilloscope.
