7 Best USB oscilloscope for hobbyists & professionals (2023)

We all know an oscilloscope is a device that we use to plot signals. Signals are plotted in amplitude vs time. Which gives us a realistic idea about the nature and shape of the signals.

Since signal analysis is so useful for circuit designs. That a lot of manufacturers started producing oscilloscope way back then. The first scope was based on the cathode tube technology and was analog.

With time, we started manufacturing digital oscilloscopes as well. And now we have USB oscilloscopes as well.

USB oscilloscope is a small version of an oscilloscope that in my opinion are designed for hobbyists and casual user of oscilloscopes. But if you are professional then my recommendation is to look for a bench top scope.

Now, if you are a new buyer of USB oscilloscope, probably you may have a lot of questions. Like what parameters to look for in the best USB oscilloscope. Which brand to check out? And perhaps a lot more similar questions as well.

Well…

I have written this article just for you so you can select your first USB scope as effectively as possible.

At the end of this article, you should be able to:

• Know what is a USB oscilloscope
• Is USB better than a bench top oscilloscope
• Technical parameters to look for
• List of some best USB oscilloscopes that you can choose from

Sounds interesting? Then I am sure you will enjoy the rest of this article as well.

Let’s get started.

Best USB oscilloscopes

Benchtop oscilloscopes are the first priority if you are a professional or want to use oscilloscopes for a long time.

But if you are a hobbyist, or don’t have the budget yet, or just want to play with some small electronics projects, then a USB oscilloscope is the better option for you.

People often go with a USB oscilloscope when they don’t have enough bench space. As they are very small. You can place them anywhere. Also, you can carry them with you anywhere you go.

Now, the best USB oscilloscope that I and field professionals recommend is either the PicoScope 2204A, or other Hantek 6254BD. They are the best because they come from proven brands, a lot of people have used them, are reliable, high quality, and come in very decent price tags that anyone can afford.

In the rest of this article, I talk about the above mentioned models and other top quality models as well in great detail.

Choosing the best USB oscilloscope

Following are the key technical parameter to look for when selecting your best scope. Remember, these are technical terms. Instead of these, cost, personal budget, and brand reputation should also be considered.

a. Bandwidth

In simple words, bandwidth is the frequency range that a scope can measure effectively. It is the difference between the highest frequency and the lowest possible measuring frequency.

The rule of thumb for selecting your oscilloscope is to choose the bandwidth that is at least 5 times more than the signals you will be measuring.

b. Sample rate

It determines the amount of waveform information captured and displayed on the screen. The greater the sample rate, the more resolution it has, and as a result, you have every detail of your signal on display.

A good scope should have twice the sample rate as that of the signals you want to capture with your oscilloscope.

c. Channels

I believe that you should go for two channels. As it will give you the chance to measure and compare two signals at the same time. Especially if you are working with amplifiers.

d. Software updates

USB oscilloscopes have no screen. They use their software on computers. So, go for the scope which has a reliable brand behind it. And they are constantly updating the software.

e. Refresh rate

By refresh rate, I mean how quickly the data updates on your oscilloscope computer software. The higher this rate, the better.

Alright!

Now let’s see some of the best USB oscilloscopes in the following list.

List of top USB scopes

The following oscilloscopes are selected based on the above criteria. They are the best, you can pick anyone of them.

Conclusion

You may be getting started with electronics, or you just want to have an extra tool in your lab. No matter what is the case. I can tell you that a piece of USB oscilloscope can add a lot of value.

Basically, any oscilloscope gives us the capability of measuring signals in terms of amplitude and time. With such information, we can analyze the signal properly for our systems and circuits.

Now, there are many types of scope to choose from, like old analog, digital benchtops, and simple USB ones.

My suggestion is if you want to go for a lifetime and professional scope, select the benchtop one. But if you are a beginner, short on cash, or just an electronics hobbyist, then a USB scope is the best option for you.

The selection of your USB oscilloscope should follow the following criteria:

• Bandwidth should be at least 5 times the highest possible signal you would measure
• Sample rate must be twice the highest signals
• Two channels
• Software updates on a regular basis
• High refresh rate as possible

Alright!

That is it. That is all I have for you about the best USB oscilloscopes. I hope I was helpful.

Thank you and have a grateful life.
