Best Portable and Handheld Oscilloscopes

Portable and handheld oscilloscopes have changed the game. Despite not being as powerful or as chock full of features as their bulkier bench-top counterparts, portable ‘scopes are capable of doing exactly what is expected of them—and then some. There are dozens of handheld oscilloscopes out right now that can do more than just track and analyze voltage changes over time. In fact, their portability is what makes them preferable over traditional models during fieldwork and field applications. Some professionals even use portable ‘scopes in conjunction with bench-top ‘scopes to get the best possible results.

As with traditional oscilloscopes, there are a ton of technical factors to consider when choosing a portable or handheld oscilloscope: size, weight, price, memory, warranty, maintenance, input impedance, features, etc. These should all be weighed with regards to what you need the device for.

Always remember, though, that your specific needs for the ‘scope are paramount, and should hold more weight than a general five-star rating.

Here is a list of the handheld oscilloscopes we will cover:
