An oscilloscope is a versatile electronic instrument that can be used for a range of critical measurements. These instruments are also known as o-scopes in short. Oscilloscopes come in a range of sizes, shapes, and prices. When trying to find the best oscilloscope for your lab, it is important for you to look at the features that they come with. Are you feeling too lazy to check out from a huge list? I have done the research for you and put together a list of the best oscilloscopes from my favorite eCommerce site – AliExpress. In AliExpress, you will find a huge collection of excellent oscilloscopes at affordable rates. Continue reading for an exciting journey.
Oscilloscopes are instruments that are mainly used for graphing an electric signal as it varies over time. Most of the oscilloscopes that we get produce a two-dimensional graph that lets you do a number of things. With this device, you can see how electric signals change over time. These devices are used in the medical industry for various measurements. Doctors use this instrument to monitor brain activity through EEG, muscle activity through EMG, and the heart through ECG.
An oscilloscope looks like a TV from the golden days. A traditional oscilloscope also works almost the same way as the traditional Cathode Rat TVs that we had as kids. In a TV, electric beams hit the back of the screen that is coated with a special chemical called phosphor. When the beam hits it, it lightens up to form a picture. You do not realize the time intervals that go in between, and we are hit back with pictures on the screen. This process keeps repeating itself again and again, and so we see the pictures moving on our TV screen.
An oscilloscope works in a similar fashion, but instead of pictures, it draws wave shapes. When the circuit in an oscilloscope senses any sort of electron movement, it does two things. It measures the path of the electrons and the intervals between them. This process takes place at a lightning speed.
There are several things that you need to consider before you make your choice. Here are some things that you must check out before buying an oscilloscope:
- Analog or Digital
- Sample rate
- Memory depth
- Triggering capabilities
- Input ranges and probes
- Form factor
Consider all of these factors before you finally make your choice.
You should choose an oscilloscope with a bandwidth that is at least five times higher than that of the fastest digital clock rate in your system under test.
Unlike other devices, an oscilloscope gives you real-time reading. You get the right reading as soon as you connect your oscilloscope to a power source. Other devices only give you voltage readings.

This is a digital oscilloscope that comes with an ARM Cortex M3 processor and a 2.4-inch TFT screen. It can display several waveform parameters, such as frequency, period, duty ratio, and more. The kit comes with instructions that make it easy to install and operate. The oscilloscope comes with three trigger modes – Auto, Normal, and Single. With these modes, it is easy to capture waveforms. Thanks to the short-circuit and open-circuit detection, you can easily find out if there is any soldering error. It has an analog bandwidth of up to 200 kHz. This handheld oscilloscope is excellent when compared to others. The price is also quite inexpensive.
This is an oscilloscope with a 110 MHz bandwidth across two channels. It comes with a 2.7-inch TFT LCD screen with a resolution of 800 X 480 pixels. It supports cursor measurement. This extremely popular oscilloscope gives you a real-time sampling rate of up to 1gsa/use. It comes with an automatic range function. It also supports horizontal, vertical, and single waveform tracking.
The oscilloscope comes with a built-in 6-bt hardware frequency meter, which is quite amazing as it can measure 2Hz – 20MHz. You will also find that it has 30 kinds of automatic measurement functions and can also customize the measurement menu. Yet another fascinating feature of this oscilloscope is that it has the waveform interception function. I am sure you will love this affordable and portable oscilloscope that is also ultra-quiet. It also does not consume a lot of power.
This is a digital tablet oscilloscope that comes with a powerful 100M bandwidth across two channels. It can measure two different signals at the same time. It has a real-time sampling rate of up to 1GS. This is a highly practical and cost-effective oscilloscope that will be a great lab companion to you. It has a 7-inch touch screen with TFT LCD display. It supports bright colors and high contrast. The touch screen is the same that we get in our smartphones today.
The oscilloscope comes with a built-in 6000mAh rechargeable polymer lithium-ion battery that gives you a standby time of four hours. It also has three trigger modes – automatic, normal, and simple. These can be used to test several measurements. The oscilloscope will also not have sudden burnouts as it is built with high-voltage protection modules.
All in all, this is a convenient oscilloscope that is inexpensive and complete with all features that you need.
This is yet another portable and convenient oscilloscope. It is a great product for engineers, thanks to the three universal test instrument functions it has. It is an oscilloscope, a waveform generator, and a multimeter, all mixed into one. It comes with a replaceable lithium battery; it also has been designed in a way that it consumes less power. After a full recharge, it can be used continuously for an entire day. It can be used on standby mode for more than two months.
It comes with a digital voltmeter function that lets you measure frequency and amplitude automatically. It also comes with six groups of waveform storage that makes using it quite simple and effective.
The easy-to-use and convenient oscilloscope is something that you need to get today for a worry-free use.
If you are a beginner, this is the perfect oscilloscope for you. It is an excellent choice, even if you think all the buttons on it are overwhelming. This is a handy oscilloscope that will not trouble you with any bugs or issues. It has a bandwidth of 70MHz, which is excellent for those who are only just beginning.
