An oscilloscope provides you with more information than the standard multimeter (both analog and digital) by graphically showing you the waveform of voltage that can then be analyzed for some properties such as frequency, amplitude, rise time, time interval, distortion, pulse width, and others.
Based on the display, there are two types of oscilloscopes available. The old and early-type known as CRO (Cathode Ray Oscilloscope) used cathode ray tubes (CRT) as their display screen. While the modern one known as DSO (Digital Storage Oscilloscope) is continuously superseding and replacing the CRO types nowadays.
Regardless of your experience or occupation that you have at the moment (whether you are a professional, beginner, hobbyist, automotive maniac, or even a collector), we hope that this article could help you as a guide or reference.
Here, we cover the top 10 oscilloscopes and try to categorize them in each class. Things to consider before buying an oscilloscope are also included in this article so you may do your research in the future.

Things to Consider Before Buying Oscilloscope
It determines the maximum frequency that it is able to measure accurately. The easiest way is to use ‘the five times rule” which means that you have to multiply the frequency you want to measure by five. Make sure you do not skip this parameter as it will affect the accuracy of the measurements.
2. Rise Time
Fast rise time is needed for accurate time measurements. Rise time as k/bandwidth where k is between 0.35 for scopes with bandwidth <1 GHz and 0.40 to 0.45 (>1GHz).
3. Matching Probes
The best way to get precise measurements is to use the probe from the same manufacturer. It must match the bandwidth of the scope.
4. Input Channels
In a simple way, the more channels the scope has, the better. However, it will also increase the price. It always depends on your need. If it is only needed for comparison of signal timings of waveforms, then two or four channels should be enough. In other case such as debugging a digital system with parallel data, 8 or 16 channels are better.
5. Fast Sample Rate
It explains how often an oscilloscope samples the signal such as the frame rate of a movie camera. The ‘five times rule’ also applies here that it means to use a sample rate of at least 5x of the highest frequency component.
6. Versatile Triggering
It helps the users to give a stable display and lets them zero in on specific parts of complex waveforms. When the scope has wider trigger options, it means that you can find the problem cause root faster.
7. Long Record Lengths
The bigger the record length, the better. The oscilloscope is able to store only a limited number of samples. The complete waveform record must have a certain number of points. It is called record length.
8. Powerful Waveform Navigation and Analysis
The users need tools to automate the process and accelerate finding specific waveform errors. Tools such as Zoom & pan, Play & Pause, Marks, Search & Mark, and Advanced search are necessary in the case to find specific waveform errors.
9. Automated Waveform Measurements
It makes it easier to get accurate numerical readings. Today, many digital scopes provide mean and RMS calculation, duty cycle, and other math operations. Even users can write their own formula for specific math functions.
10. Advanced Application Support
Advanced scopes are equipped with application software for optical and electrical design troubleshooting and standards compliance. This kind of software is really needed for those who work in the electronic world moreover in the research and development field.
11. Easy, Responsive Operation
The scopes must be easy to use and responsive quickly to any small change of events. AUTOSET and/or DEFAULT buttons will help even occasional users for instant setup.
12. Connectivity and Expansion
The users might have a need to connect the oscilloscope to a computer or transferring data via portable media which allows advanced analysis and simplifies documenting and sharing results. Standard interfaces such as USB is useful for USB flash drives to store waveforms, captures, and settings. It also includes interfaces like GPIB, RS-232, Ethernet, and LXI, and links to network communication modules.
13. Cost of Ownership
At the end of the day, it is not free to get an oscilloscope. Making sure to get the priorities right is a must for every user before purchasing one. If the need is able to be fulfilled with the medium quality scope or even the cheap one, then no necessary to buy an advanced one.
Time to Decide: Which Oscilloscope to buy?
So, here we are. We have arrived at the conclusion stage. Oscilloscopes are manufactured so that people can monitor and analyze the electronic signal waveforms which they could not do by using a standard multimeter. The most important thing to consider is always bandwidth. The price comes after.
After doing some researches on our own, Siglent SDS1202X-E is the best choice we could recommend you to buy. It is superior in both features and performance. On the price tag, it is totally worth the price compared to its competitor Rigol DS1054Z.
