Best Portable Oscilloscope Reviews

An oscilloscope or o-scope is a device that measures voltage. By using a probe it measures the voltage between two points across the battery. An o-scope plots the voltage change in time and not just every second, it can measure the voltage changes in every nanosecond. These things can be incredibly fast. The vertical axis displays the voltage level and can be adjusted using a knob, and a horizontal axis is for the time that can also be adjusted using the other knob. There can be plenty of options to choose from in the market but getting just the perfect one according to your specification can be a trouble. Here, we have listed the 10 best portable oscilloscopes to help you find yours.

Buying Guide

Analyzing and tracking voltage fluctuations and monitoring their behavior is an important part of any electrical task. Can you imagine taking a full-size oscilloscope everywhere to your work? Well, this is what saves your day—an oscilloscope portable. Before buying an oscilloscope, several technical factors are considered, and it is important to look into portable oscilloscope reviews. Here we are going to discuss a few points to help you know what to look for in the best portable oscilloscope.


If you are looking for a portable oscilloscope, it is evident that you need something that you want or need to carry regularly, and for that, your oscilloscope has to be lightweight, small in size, and heavy-duty. Before choosing your oscilloscope, make sure all your requirements are matching the product’s features.


You surely do not want to carry a brick in the pocket in the name of an oscilloscope. For this reason, a portable digital oscilloscope not only has to be small in size but also lightweight. Some portable oscilloscope multimeters can do more than just note voltage frequencies; you need to know what you want.


If you want an oscilloscope that can save and transfer data and images from the tool itself, that is not a problem. An oscilloscope now has a built-in memory capacity to store and save data in the machine.


An oscilloscope does not have to be very expensive to meet your requirements. If you can find a tool that can do the job you are looking for, there is no need to be extra cautious about the price tag. There are plenty of pricey tools that do much more than the task you need it to do. So look for the specifications and features and select something worth your money.

How to use portable oscilloscopes storage?

There are two types of oscilloscopes used to plot voltage change in time, and operating each one of them can be different. Also, there are three in one or two in one oscilloscope in the market, which will again vary from each. The two types of oscilloscopes that are most commonly used are CRO and DSO. A CRO is a cathode ray oscilloscope, and the latest one available in the market is the DSO. Let’s see what you will find in a regular two-channel oscilloscope and what is the work of each option.

Knob and buttons

If there are two or more channels, you can see that on the screen in different colors. You will also find different buttons for each channel menu. You will see a knob to adjust for time or seconds that will adjust the horizontal speed frequency of the oscilloscope. The x-axis on the screen will most commonly represent time. To adjust volts per division, there will also be a knob. Each one of these settings will display on the screen. The menu will be similar on the different channels as well.


Different channels will have different menu buttons. You can see the input coupling that you can change to DC, AC, or ground. You will also find different on/off buttons for each channel.


An oscilloscope will also have a probe multiplication factor which can be set according to the different probes. There are also options to invert your signal.

Map menu

There is also a map that performs various operations on your signals like addition, subtraction, multiplication, division. An FFT feature is the fast Fourier transform that is very similar to a spectrum analyzer.

Trigger menu

From the trigger menu of the DSO, you can select the type, source of the horizontal sweep oscillator. There are some more options on the trigger menu which you can see the details on the oscilloscope screen.

How does a portable oscilloscope measure sound signal?

A microphone connected to the oscilloscope will show you pictures of a human voice. The pitches a voice creates and the patterns are all displayed on the screen of an oscilloscope.


A sound is a wave that is caused by vibrations in the air. A music sound, a whistle, produces a sine wave which you can see in the oscilloscope. Similarly, when we talk, it is made up of irregular waves, and because it is a combination of sounds, the oscilloscope adds them all together and shows the result on the screen.


Sound can be seen through a microphone when it is connected to an oscilloscope. A microphone changes sound wave I to an electrical signal with the help of an oscilloscope. With the sounds with only one frequency, like a whistle or tuning fork, the wave looks regular and smooth, and these are called a sine wave. High-frequencies have high notes, and those waves are close together. The low notes have a low frequency, and unlike high notes, the waves are spread out. Singing or violin are regular sounds, and they make waves not so smooth and repeat themselves.


What is the best portable oscilloscope to buy?

The best portable oscilloscope for you would be the one that has everything you need. There are various oscilloscopes in the market claiming many features which also varies in price. But a special mention to Fluke portable oscilloscope. They have an excellent reputation in the market for their precision and durability.

Is the portable oscilloscope a voltmeter?

An oscilloscope is a voltage measuring device in the circuit just like a voltmeter. Also, the CRO (cathode ray oscilloscope) is a powerful tool for measuring voltage change; it acts as a voltmeter. But an oscilloscope and a voltmeter are two different tools.

What is a portable oscilloscope used to measure?

An oscilloscope measures the voltage change in time, these devices are so fast that they can measure not just every one second but it can measure in every nanosecond. They are exceptionally quick and often give precise results. A portable oscilloscope is a great alternative for large scale measuring tools. They are handy, lightweight and easily accessible.

What is the basic function of a portable oscilloscope?

An oscilloscope is a tool used for measuring voltage fluctuations. These are exceedingly rapid and show the quick result of even one nanosecond voltage change. It has a vertical axis that shows the voltage level as a horizontal axis for the time. Both of these can be adjusted using a knob in the oscilloscope.

What are the limitations of a portable oscilloscope?

The analog type oscilloscope does not have a memory space and can only show the results in real-time. The digital oscilloscope only uses μP, ADC and acquisition memory for measurement. It can be very expensive, some of them do not provide 100% authentic results and can be too heavy to carry.

Final Verdict

A portable oscilloscope is a great tool for everyday use and also for educational purposes. They are handy, light, portable, and give maximum mobility. Some of this oscilloscope even does multiple works, which cut down the cost of buying other devices. There are plenty of choices in the market to choose from, and there are also various price ranges and features. Buying an inexpensive portable oscilloscope is a great start for newbies. This tool will show voltage and sound frequencies, the digital ones can save data, and some can also transfer. The latest oscilloscopes have a high-quality LCD screen that shows vivid results on the go.
