Oscilloscopes are essential measuring instruments that any electronic system designer or electrician cannot afford to lack. It doesn’t matter if you are a professional or a technician. You need this instrument to help you know if you have the appropriate signal in your design.
Electrical signals such as voltage and currents in any system are invisible. You need an oscilloscope to display and analyze them to understand how the system works or to troubleshoot problems. The device makes it possible by plotting a graph of an instantaneous electrical signal as a function of time.
The oscilloscopes you find in electronic labs are heavy and practically not portable. Or, you don’t have the budget to buy such advanced equipment for simple DIY projects. That is where handheld oscilloscopes come in. These are highly portable and very affordable. Some of them even fit into the pocket. So, carrying them around is never a problem.
Looking for a handheld oscilloscope can be challenging because of the different brands and models on the market. Fortunately, you don’t have to struggle anymore because we have done the hard work for you. This article is a detailed review of the best handheld oscilloscopes in 2022. Read on for details!

Buying Guide for The Best Handheld Oscilloscopes
There are different parameters you have to consider when looking for a handheld oscilloscope. Portability is the primary factor in this case but also check the following:
Any engineer or a technician looking for the best oscilloscope considers bandwidth a primary factor. It is a range of frequencies within which the instrument can still give accurate measurements. The unit is usually in MegaHertz. To find what will work for your application, multiply the frequency of the signals you intend to measure by five and use the result as the minimum bandwidth requirement.
2. Sample Rate
As the name suggests, it is the number of signal samples that an oscilloscope can capture per second. The higher the sample rate, the more detailed the waveform will be displayed on the screen. With a high sample rate, instantaneous signal changes and spikes can be detected and captured by an oscilloscope.
3. Memory Depth
Memory depth is an equally important feature of an oscilloscope if you have to store some waveforms for future analysis or reference. This parameter refers to the number of waveform samples an oscilloscope can store. It depends on the internal memory size or external memory device that can be interfaced with the oscilloscope.
4. Number of Channels
Most handheld oscilloscopes are dual-channel measuring instruments, but you can find 4-channel ones. These can display two separate signals for comparison. What you go for depends on the number of electrical signals you want to view and analyze at a go.
The last and equally vital parameter to consider is the cost. The handheld device you will buy depends on your budget. If you can afford the high-end products, go for them because they are more accurate and reliable. Otherwise, budget-friendly oscilloscopes are a better option.
That marks the end of our review of the best handheld oscilloscopes. So, which is the best product to buy and why? Your choice depends on the budget, but the following are our recommendations:
All in all, Fluke 190-102 handheld oscilloscope remains the best option. It is a high-performing measuring instrument from a reputable manufacturer. Additionally, it has high bandwidth, sampling rate, and memory depth. You can use it in many applications while still getting the best.
YEAPOOK ADS1013D oscilloscope is another good option if your budget allows it. It equally has high bandwidth, signal sampling rate, and memory depth. However, it stands out with its crystal clear 7-inch display screen and most useful waveform math functions. You get detailed waveforms for better analysis.
Like the previously recommended products, Siglent SHS806 Handheld Oscilloscope has relatively high bandwidth, sampling rate, and record length. It also boasts of portability and offers a digital multimeter mode for measuring voltage, current, frequency, power, and duty cycle of electrical signals.
