15 best oscilloscopes from Aliexpress

There are situations when it is necessary to make complex multifaceted diagnostics, but with an on-site visit. An ordinary pocket oscilloscope will not work here, and it is difficult and inconvenient to carry a bulky instrument with you. Oscilloscope DSO5102P in such a situation will be simply indispensable. Firstly, the device is thinner than its counterparts, and there is a comfortable handle on the case. The manufacturer failed to significantly reduce the case, since in this case the functionality would have to be sacrificed, and we have before us a professional, not an amateur oscilloscope. There is a function for recording a signal and its subsequent display. Well, of course, the USB connection option, which has already become familiar on devices of this kind.

RIGOL DS1202Z-E is a professional stationary oscilloscope. The device is the most accurate and reliable, designed to work in laboratory conditions, where measurement clarity and the presence of a large number of functions are required. This is the best option for craftsmen, and its only drawback can be considered a high cost. Yes, the tool definitely cannot be cheap, given its technical characteristics, but by the standards of AliExpress, the price tag is clearly high. However, the brand is known in a certain environment, in addition, the range allows you to choose a device for specific purposes. Cheap modifications may have fewer functions, but the measurement accuracy will not change, since the working module is the same.

This oscilloscope cannot be classified as portable because it is powered by the mains. But the dimensions of the device favorably distinguish it from stationary analogues. The bandwidth is small, and the memory will not allow you to save the waveform. But the device quickly and accurately measures any parameters. The screen quality is average: with vertical rotation, the picture remains clear and bright, but the horizontal viewing angle leaves much to be desired. Even if you turn the display slightly to the right or left side, the image fades. In the reviews on Aliexpress, the DSO150 is most often praised, the shortcomings can hardly be called significant. Buyers don't like the complicated assembly of the oscilloscope and the lack of a European plug.

For those who want to save money or have fun building an oscilloscope on their own, there are special DIY kits on AliExpress. The Gaqqee DSO138 model is sold in two versions - an already assembled device or a kit of parts.All this fun is relatively inexpensive. According to the characteristics, the oscilloscope is not inferior to the HLFEC DSO150, and weighs even less - only 156 g. The buyers were not quite satisfied with the product package. There is no power supply in the package, there are not enough bolts, and it is better to buy probes separately. But there is a detailed instruction, and the quality of the parts significantly exceeds the price. Among the minuses, only delivery is mentioned, which can take several months.

This oscilloscope fell into the stationary category largely due to its technical equipment and the presence of 28 measurement functions. As for the dimensions, they are quite compact here. The device requires individual placement in the workplace, but the thin body allows you to install it even in a small area. The brand deserves special attention. This is a Chinese company, but well-established, and widely known to professional users. In addition, the reviews say a lot about the convenience of the tool and the working panel.A lot of buttons are well placed on the body, and the bright liquid crystal display does not create glare and does not interfere with tracking the received data.

An oscilloscope is the most unique tool: the smaller it is, the more functionality the manufacturer manages to install there. For example, this portable model has 16 working channels at once, taking into account the fact that in stationary types there are usually two, a maximum of four. And all this in a compact package and with the most simple operation. It is difficult to say how this is possible, but let us conclude: the seller or manufacturer is a little cunning when they put such characteristics. Most likely, the parameters are too high to attract customers. In reviews on Aliexpress, they write that the oscilloscope has a real bandwidth limit, and it was set at around 10 megahertz.

With a mobile oscilloscope, you have to work in not the most convenient conditions. Often on weight or with installation on an uneven, small surface. The form factor of the device in this case becomes a very important criterion, and we have before us the best model with which you definitely will not experience any inconvenience. The device fits perfectly in the hand. The lower part is narrowed and has notches against slipping. At the top, the case expands, allowing you to place a quite decent display for such a compact device. There are quite a lot of buttons, but they are very well thought out and will make it easy to handle the device even with one hand. As for technical characteristics, they traditionally lack stars from the sky.

The FNIRSI 1C15 model has become a favorite of many buyers from AliExpress. The package contains everything you need to work with the oscilloscope: a probe, a USB cable, a carrying case and an English-language instruction. For control, not only buttons are used, but also a joystick-slider. This will seem convenient to some, although reviews sometimes criticize this decision. Visually, the device does not inspire confidence: the plastic is flimsy, the charging connector is too deep, and the case turned out to be bulky. But this does not affect the operation of the FNIRSI 1C15 in any way. The signal is almost perfect, there is no distortion in the sinusoid. The device correctly determines the frequency and other indicators, but with an increase to 70 MHz, the accuracy drops noticeably.

This device can be classified as professional. Yes, it does not have such extensive functionality as stationary oscilloscopes, but the tool does not pretend to be. All information is stored in the internal memory module and, if necessary, can be easily transferred to a computer with any operating system. The high-definition liquid crystal display deserves special attention. It does not glare and produces the clearest picture. Successfully selected color display of the resulting picture. The yellow wave is perfectly visible on a black background and does not merge, which allows you to accurately determine its parameters. In the reviews, they often write about the quickness of the seller and the quick dispatch of the goods to the customer.

Older people who work with oscilloscopes are used to the fact that this is a large and complex instrument that works almost stationary. But technology does not stand still and we have a full-fledged oscilloscope that fits easily into your pocket and at the same time is not inferior in functionality to its older counterparts. Some functions directly affect the operation of the device, for example, the mode of saving the history of signals and the ability to display them on the screen. Others are just nice little things, like night and day mode. If we talk about reviews, in them buyers often praise the lack of flickering of the display. It is worth noting that this is a drawback of many models, and here the developers managed to fix it.

The description immediately states that the tool is not the most powerful and has extremely limited functionality. It has the lowest throughput among similar devices, and it will not work to perform some complex and high-precision diagnostics with its help.But for frequency use and current analysis, an oscilloscope is quite suitable, and the price pleases. The device supports a flash card and has a built-in memory module. All received data is easily stored and then transferred to a computer for their study. Compactness can also be considered an advantage, but this is also a disadvantage, since some buttons turned out to be very small, and the displayed data on the screen is often difficult to read.

Perhaps the appearance is not important, but it is much more pleasant to hold a compact and high-tech model in your hands. Before us is just such an oscilloscope. There are not a bunch of buttons and toggle switches, but the device allows you to make the most complex measurements with the highest accuracy. In this case, the entire control of the device takes place using a sensor with high sensitivity. It enables and disables functions, and also allows you to scroll the image in two planes and reduce its display by enlarging or reducing the image.Simply put, this is direct evidence that even such a complex instrument as an oscilloscope can look modern and stylish, without sacrificing functionality.

KKMOON ADS1013D is not the most popular oscilloscope on AliExpress, although this tablet model is instantly sold out in other stores. She has a giant display with good resolution and a capacious battery. 1 GB of internal memory is enough to store thousands of screenshots and data sets. Vertical scan settings are independent, simultaneous use of 2 channels is allowed. The device is suitable for checking sensors, setting up amplifiers and power supplies, but it will not work with digital circuits. The reviews write that the oscilloscope is well made, the stand is comfortable, the sensor is responsive. Management cannot be called intuitive, but everything is described in detail in the instructions.

The model in a compact body, powered by a low-capacity battery, is capable of performing diagnostics comparable to stationary models. The best option for professionals who often work on the road. In addition, the information received can be transferred to a flash card, so that later the data can be studied in detail in a workshop or laboratory. Among the shortcomings, one can single out a small display, which can cause certain difficulties in studying the data received. Judging by the reviews from Aliexpress, some of the displayed elements on the screen are so small that they have to be closely examined. But the tool will easily fit in your pocket and will not take up much space in your work suitcase.

Lieve DS212 has advanced functionality with a small bandwidth. It has a large display and has a built-in signal generator. There is enough memory, control is convenient thanks to 2 encoders and auto-tuning. Despite the metal case, the oscilloscope turned out to be light and compact. It is well assembled, the package is complete, there is even a hex key and instructions in English in the box. For full-fledged work, it is necessary to order an additional probe for X10 (only X1 is included in the kit). The main reason for the negative reviews about the product was the battery - its capacity is only 500 mAh. Because of this, you will have to keep a charger on hand at all times.
