Selecting the Right Oscilloscope

If you’re about to invest in an oscilloscope, you need a checklist of what you should look for and why. Part I of the blog, Tips: How to Select an Oscilloscope Before You Buy, covers the details when shopping for an oscilloscope in terms of bandwidth, sample rate, number of channels, display quality, memory depth, and segmented memory. 

Part II covers what you should look for regarding an oscilloscope’s waveform update rate, triggering, serial bus applications, measurement, analysis, connectivity, the ability to share remotely, test automation, and document-generating capabilities.


Frequently Asked Questions - Handheld Oscilloscopes

What is a handheld oscilloscope?

A handheld oscilloscope is a portable, compact device that for measures and displays electrical fields. They generally have a built-in display, battery power source, and an intuitive interface, enabling you to conduct measurements and diagnostics in the field.

How does a handheld oscilloscope differ from a traditional benchtop models?

Handheld oscilloscopes are different from benchtop models in the following ways:

Portability: Handheld oscilloscopes are smaller, lighter, and usually battery-powered, making them easy for you to carry and use in various locations.

Functionality: While handheld oscilloscopes offer many of a benchtop model’s measurement capabilities, they may have fewer features and less processing power due to their compact size.

Usability: Handheld models are use in the field, with rugged exteriors and simplified interfaces to facilitate quick measurements.

Display: They typically have smaller screens instead of the larger, more detailed displays on benchtop models.

What are the typical applications for handheld oscilloscopes?

You can use handheld oscilloscopes in several ways, including:

Field service and maintenance: Troubleshooting and maintaining electrical equipment, machinery, or systems in the field.

Industrial control: Monitoring and diagnosing problems in industrial processes and automation systems.

Automotive diagnostics: Analyzing electrical signals in automotive systems for diagnostic purposes.

Education and training: Providing students and trainees with hands-on training in electronic signals and systems.

Research and development: Conducting experiments or tests in environments where traditional oscilloscopes are impractical.
