Oscilloscopes are powerful tools that are useful for designing and testing electronic devices. They are vital in determining which components of a system are behaving correctly and which are malfunctioning. They can also help you determine whether or not a newly designed component behaves the way you intended.
This application note provides an overview of oscilloscope basics. You will learn what an oscilloscope is and how it operates. We will discuss oscilloscope applications and give you an overview of basic measurements and performance characteristics. We will also look at the different types of probes and discuss their advantages and disadvantages.
Here are a few simple ways to improve your operation and measurement capabilities.

In less than 30 years, forensic measurement methods have evolved from using tape measures to total stations, and now 3D laser scanners. So, what is a laser scanner and why should you, as a crime or crash scene investigator, use one? A laser scanner allows an investigator to capture an accurate, 360-degree digital model of a crash or crime scene, in the form of millions of X,Y,Z data points. You can use these data points, called a ”point cloud,“ to create diagrams and obtain exact measurements of anything that was in the laser’s path and review it, years after the scene was scanned.
The differential CAN bus, which is used extensively in automobiles for drive-train and body control, is based on asynchronous transmission of packets of data from multiple nodes in the system. The CAN bus is also used in many non-automotive applications including control of industrial machinery, as well as medical equipment. Because of the asynchronous nature of packet transmission, there are often collisions of data when two or more nodes begin transmission at the same time; or nearly same time.
Many people would say their car could never have too much gas mileage or their house could never be too large. On a similar note, many oscilloscope users would say their scope could never have too much acquisition memory. But, just like there are tradeoffs in gas mileage (less acceleration for example) or in the size of your house (more costs to heat/cool), depending on your oscilloscope architecture there may be very real tradeoffs in more acquisition memory.
As data rates continue to increase in today’s state-of-the-art high-speed digital designs, timing budgets are decreasing. Ensuring that serial data signals are valid and stable when receivers sample the data often requires an understanding of the effects of the various components of jitter that may contribute to decreased valid data windows. The primary measurement tool used today by hardware design engineers to capture and view waveform jitter is an oscilloscope.
Using the correct oscilloscope power measurement techniques is critical in order to make repeatable and accurate power measurements on your design. Make sure that you know the latest best practices by reading this application note, which covers tips to achieve the maximized measurement dynamic range and probing techniques to optimize signal integrity.
When debugging digital designs, it is often difficult-to-impossible to set up an oscilloscope to trigger on specific and unique signal problems. The Keysight Technologies Inc. Zone Trigger, which is available as a standard feature in all InfiniiVision 3000T, 4000 and 6000 X-Series oscilloscopes, can be used in conjunction with conventional oscilloscope triggering to quickly zero-in on problem signals. If you can see the problem signal, then you can trigger on it using Zone Trigger. Learn how to easily use Zone Trigger to capture non-monotonic edges, set-up and hold-time violations, and serial bus arbitrations.
