FREQUENTLY ASKED QUESTIONS - Oscilloscopes
WHAT IS AN OSCILLOSCOPE?
An oscilloscope, sometimes shortened to “scope” or “o-scope”, is a test instrument that captures and displays the behavior of electrical signal over time.
WHAT ARE THE DIFFERENT TYPES OF OSCILLOSCOPES?
All modern oscilloscopes are digital storage oscilloscopes (DSOs), which use digital signal processing to capture and display the analog signal. If the scope has the ability to accept digital signals, it is a mixed-signal oscilloscope (MSO). If the scope has a spectrum analyzer feature built into it, it is a mixed-domain oscilloscope (MDO), though this terminology is less common.
WHAT IS AN OSCILLOSCOPE USED FOR?
Oscilloscopes play a key role across all industries for a variety of applications (troubleshooting, validation, characterization, manufacturing test) and technologies (high-speed digital electronics, optical communication, RF, power electronics). An oscilloscope is a critical test instrument to observe, analyze, or record, the behavior of an electrical signal.
HOW DOES AN OSCILLOSCOPE WORK?
An oscilloscope uses a probe to connect to a test point in a circuit and amplifies or attenuates the voltage at that point. . The signal path after that depends on the scope, but in general analog circuitry conditions the signal and an analog-to-digital converter digitizes it for further evaluation, processing, and analysis.
WHAT’S THE DIFFERENCE BETWEEN AN OSCILLOSCOPE AND A SPECTRUM ANALYZER?
An oscilloscope captures and displays a signal in the time domain, while a spectrum analyze captures and displays a signal in the frequency domain. Sometimes an oscilloscope will have a spectrum analyzer feature built into it for convenience of analyzing the signal in the time and frequency domain.
HOW DO YOU USE AN OSCILLOSCOPE?
Keysight offers a wide range of free technical resources for engineers to learn about essential oscilloscope functions and specifications. Get started with the How to Use an Oscilloscope Keysight University Course, and continue your learning with free Oscilloscope Technical Resources.
