Oscilloscopes (i.e., scopes) are one of the primary tools in a test and measurement toolbox. This TechXchange collects articles and videos about using and selecting scopes. Part of the challenge of covering these tools is the various versions, including USB-based, portable and desktop models as well as analog versus digital scopes.
A Little Oscilloscope History
One of the most basic pieces of test equipment is the oscilloscope (i.e. scope). They have been around for decades (Fig. 1), but many of the techniques used with a scope apply to the analog scopes of old and digital scopes of today that have more computing power than many supercomputers of the past.
Originally, analog oscilloscopes employed cathode ray tubes (CRTs) to present electrical signals. Analog circuits controlled the scanning beam of the CRT. These days, digital oscilloscopes employ digital displays and use high speed analog-to-digital converters (ADCs) to record the signals.
The first commercial scope was released in 1931 by General Radio Company (GenRad). Other earlier oscilloscope OEMs included Rohde & Schwarz and Hewlett-Packard. Tektronix followed a few years later in 1946.
Here are some historically oriented articles about oscilloscopes and test technology.

What's the Difference: Oscilloscopes
Not all oscilloscopes are equal. These articles look at the differences between various scopes, functions and features.
Choosing an Oscilloscope
So you want or need an oscilloscope. There are a wide variety and probably quite a few scopes that will meet your needs. If you have used a scope in the past, then you probably have a good idea of the capabilities you're looking for.
On the other hand, if you want to know what to look for, or what might be new in the market, then check out these articles designed to provide more insight into the scope selection process.
Choosing Oscilloscope Probes
Oscilloscopes don't operate by themselves. They need to be connected to the device being tested via an oscilloscope probe, also known as a test probe.
Probes have different operating characteristics and purposes. These articles cover some of the details to consider when selecting a test probe.
Using an Oscilloscope
Ok, you have a scope in hand or sitting on the lab bench. What are you doing to do with it?
Sometimes the use of an oscilloscope is obvious, for instance, measuring the voltage or current at a point in a circuit. This may become a little more challenging, though, due to a variety of factors. These articles look at some of the basics.
Advanced Oscilloscope Techniques
Oscilloscope development and use continues to advance. New features lead to new diagnotic and testing techniques.
Interesting Things To Do With an Oscilloscope
Oscilloscopes are a basic test and measurement tool, but sometimes engineers come up with interesting uses for these tools.
