Which of these 7 USB oscilloscopes is right for you?



From entry-level to professional, PC-based USB oscilloscopes are becoming more diverse. PC-based oscilloscopes with USB connectivity provide a wide range of performance levels at an affordable price. From entry-level to sampling oscilloscopes with high bandwidth, and new versions that support more features are coming soon.

Combining new features, portability and PC processing power, PC-based high-end USB oscilloscopes are beginning to be functionally comparable to desktop oscilloscopes at much lower cost. The PC interface simplifies file processing and editing, making it easy for users to write their own programs to control the oscilloscope.

The USB oscilloscope is easy to connect and can be moved at will, almost anytime, anywhere. We have selected seven models from a variety of oscilloscopes, listed in order of cost from low to high.


Hantek HT6022BE

If you need a small, lightweight, inexpensive entry-level or amateur PC oscilloscope for basic testing, the Hantek HT6022BE will meet your requirements. The oscilloscope costs only $70, so there is only 20 MHz of bandwidth -- this number is lower than most of the oscilloscopes listed in this article, but it still has merit.


This two-channel oscilloscope is best suited for notebook computers, is small in size, easy to carry, has a high refresh rate, and has a real-time sampling rate of 48 MS/s. Waveform data can be sent as an email attachment, and the FFT saves the waveform on the display in TXT, JPG/BMP and MS Excel/Word formats. The oscilloscope comes with a USB 2.0 port and a standard USB XI interface, eliminating the need for an additional power cord. Supports Windows 2000, Windows NT, Windows XP, Windows Vista, and Windows 7 operating systems.

Owon VDS1022I

The Owon VDS1022I has a 25MHz bandwidth and a real-time sampling rate of up to 1GS/s. This is a 2+1 (multi-channel) oscilloscope with a user-friendly and intuitive interface that enables two types of waveforms on the same screen. There is a multi-trigger option: Edge, Video, Slope, Pulse and Alternate.

The oscilloscope also features USB isolation to reduce signal interference and provide better PC protection. It sells for $104, including USB isolation, so users don't have to pay $40 to purchase this feature separately. If you separate the USB isolation function, the cost of the oscilloscope will drop to $60. For entry-level professionals or amateurs, this is an inexpensive option.

Perytech DSO-U2200

Unlike many USB oscilloscopes that use an easy-to-implement but less intuitive window design, the Perytech DSO-U2200 dual-channel oscilloscope is more like a traditional oscilloscope, eliminating user inconvenience and confusion.

Although there are several PC oscilloscopes on the market that cost $110, I think this one is quite good. It uses accurate, versatile software that provides a variety of automatic measurement functions including maximum, minimum, frequency and period. Its overlay function stacks up to four USB oscilloscopes into an eight-channel oscilloscope. The logic analyzer mode can decode common protocols such as I2C, UART, I2S, PS/2, CAN bus, 1-Wire, S/PDIF, and Miller. The oscilloscope has a bandwidth of 60MHz and a sampling rate of 240MS/s using one channel.

Some low-priced oscilloscopes do not include hardware triggers to reduce costs, but the Perytech DSO-U2200 provides hardware triggers at such a price point, which has to be said to be tempting.

Hantek IDS1070A

The dual channel Hantek IDS1070A & IDS101 oscilloscope can be used with iOS, Android 4.0 and Windows XP or higher operating systems on tablets, PCs and iPhones. The data exchange between the tablet and the oscilloscope is via WLAN. The USB port is used to charge the internal battery and connect to the PC without a wireless connection. It can also be connected to the iPad and iPhone at the same time: operate with the iPad and watch with the iPhone.

The oscilloscope is small and lightweight, with features including waveform averaging, persistence, intensity, inversion, addition, subtraction, multiplication, division, and X-Y plots for production testing, research, and design. 70 MHz bandwidth, 250 MS/s real-time sampling rate, priced at $126.

Hantek DSO-2250

Need an oscilloscope with better performance? The Hantek DSO-2250 is also a PC-based USB oscilloscope that offers 100MHz bandwidth and 250MS/s real-time sample rate for better performance without costing you too much. This dual-channel digital oscilloscope uses a PC's USB port to transfer data at a communication rate of 12 Mbits/s to create an oscilloscope display on a PC and how to use a standard oscilloscope.


The oscilloscope is easy to use and is suitable for notebook and product line maintenance. It is very intuitive and offers PASS/FAIL checks for 23 measurement functions for technical applications. Waveforms can be saved in .TXT, .JPG, .BMP, and Microsoft Excel/Word. Operating systems include Windows 98, Windows Me, Windows NT, Windows 2000, Windows XP, and Windows Vista. The oscilloscope allows a single computer to be connected to many DSOs for easy channel expansion. Based on these features, the price is reasonable, about $ 235.

Digilent Analog Discovery 2

The Digilent Analog Discovery 2 is a versatile USB oscilloscope developed by Analog Devices and supported by the Xilinx University Program. Although small in size, it is powerful, mainly for students, amateurs and enthusiasts, and can be used to measure, display, simulate and analyze various mixed-signal circuits. The Analog Discovery 2 comes with a 16-channel logic analyzer and protocol analyzer that is compatible with Mac, Windows and Linux and sells for less than $280.


The oscilloscope provides two analog inputs (±25 V, differential, 14 bits, 100 MS / s, 30 MHz + bandwidth), two analog outputs (±5 V, 14 bits, 100 MS/s, 12 MHz + bandwidth), one stereo audio Amplifier that uses an external waveform generator (AWG) signal to drive an external headphone or speaker, 16 digital I/O (3.3V CMOS and 1.8V or 5V tolerance, 100MS/s) and two I/O digital trigger signals Used to connect multiple instruments (3.3V CMOS).

Its WaveForms software development kit includes C++ and Python libraries, examples, and forum support from software developers. Third-party software such as MATLAB and LabVIEW also supports Analog Discovery 2.

PicoScope 5000 Series

The PicoScope 5000 Series is the most powerful USB-based PC oscilloscope described in this article. The series includes dual and quad oscilloscopes with 60MHz, 100MHz and 200MHz bandwidth options. Here we choose the 5243D dual-channel oscilloscope at $1,615 with 100MHz bandwidth and 256MS of memory.


Figure: The PicoScope 5000D Series captures waveforms over 500 ms with a resolution of 1 ns.

Pico's FlexRes variable resolution oscilloscopes can reconfigure oscilloscope hardware to increase sample rate or resolution, making it a fast (1GS/s) 8-bit oscilloscope for digital signal applications or a high-resolution 16-bit oscilloscope for analog signals . Features include a SuperSpeed ​​USB 3.0 connection that is compatible with older USB technologies, extremely fast waveform retention, and a sampling rate of 500MS/s. However, the oscilloscope is here to top the list because of its large memory depth of 256MS (8-bit), allowing long-running waveforms to be captured at maximum sampling speeds – over 500 ms and 1 ns resolution. In addition, all PicoScope 5000D oscilloscopes have a built-in 14-bit 200MS / s AWG.

The PicoSDK software development kit supports continuous data transfer from device to host at speeds up to 125 MS / s, allowing users to write their own software, including drivers for Microsoft Windows, Apple Mac (macOS) and Linux (including Raspberry Pi and BeagleBone) . It also provides sample code that demonstrates how to interact with third-party software such as Microsoft Excel, NI LabVIEW, and MathWorks MATLAB.
