Best oscilloscope of 2018
Before you spend your money on oscilloscope, start by familiarizing yourself with the various types. There is a wide range of products available on the market today, and below I have reviewed 3 of the very best options.
Here are my top picks with detailed reviews, comparison charts and buying guides to help you purchase the perfect item for your needs. The above tidbits will bring you closer to selecting oscilloscope that best serves your needs and as per your budget.
Test Results and Ratings
Why did this oscilloscope win the first place?
I really enjoy the design. It is compact, comfortable and reliable. And it looks amazing! I am very happy with the purchase. It is definitely worth its money. The product is top-notch! The material is stylish, but it smells for the first couple of days. I don’t know anything about other models from this brand, but I am fully satisfied with this product.
Why did this oscilloscope come in second place?
Managers explained me all the details about the product range, price, and delivery. The material is pretty strong and easy to wash if needed. This is a pretty decent product that perfectly fitted the interior of our office. I recommend you to consider buying this model, it definitely worth its money.
Why did this oscilloscope take third place?
I liked the design. We’ve been using it for 2 months and it still looks like brand new. This price is appropriate since the product is very well built. The material is incredibly nice to the touch. It has a great color, which will suit any wallpapers. It is inconvenient to use due to the size. I am going to get something different next time.
oscilloscope Buyer’s Guide
Bandwidth is the range within a band of wavelengths or frequencies.
You must choose digital oscilloscopes with bandwidths five times higher than the maximum frequency of the signal needed to be measured.
This will ensure a more precise image of the waveform. If you will be measuring frequencies of around 100MHz, for instance, choose an oscilloscope with bandwidth of 500MHz.
This limits the error to only 3%, compared to an error margin of 5% for a 300MHz oscilloscope.
For analogs, a bandwidth of twice the highest signal frequency to be measured is usually adequate.
Be extra vigilant when buying, check the specifications or data sheet as some scopes have no available bandwidth on all voltage ranges.
For a given performance level, they also tend to be the most expensive option.
PC based oscilloscopes often offer cost-savings over their bench-top equivalents, and have the advantages of a large color display, faster processor, storage and data-sharing capabilities, and a keyboard for annotations.
PC based scopes come in two flavors: internal and external. Internal PC based scopes are usually PCI or PCIe format plug-in cards and are tied to being used with one desktop PC. External PC based oscilloscopes like PicoScopes come in very portable small boxes that connect to a PC via a USB port. They can be used with desktop or laptop PCs, making them ideal for field use, as well as for bench top design and debug tasks. There are dedicated automotive PicoScopes with isolated inputs and adapters that are specifically designed for vehicle investigations.
BEAVERTON, Ore., Oct. 10, 201— The DS2000E Series Oscilloscope, a 200-MHz, two-channel scope from Rigol Technologies is available at 100- or 200-MHz bandwidths.
All models provide two analog channels with 50 O input impedance standard. With a real-time sample rate of GS/s, memory depth of up to 2Mpts standard and waveform capture rate up to 50,000 wfms/s, the DS2000E provides the raw instrument performance required to meet today’s more advanced debug challenges.
The oscilloscope is coupled with the large 8-in. WVGA intensity graded display, complete network connectivity, hardware waveform record/playback, serial trigger and decode, and other advanced analysis capabilities.
High-speed serial networks will also require oscilloscopes that can meet their demands. Oscilloscopes that make automated measurements using add-on PC software are well equipped to answer high-speed serial communication needs. The MIL-STD-155serial bus is one example of a serial bus that is tested using oscilloscopes for signal integrity. MIL-STD-155is used largely in the control of avionics systems, as well as in military ground vehicles and space-based systems.
Conventional digital oscilloscopes may make finding signal integrity a time-consuming process. Oscilloscopes with the ability to intelligently trigger on and decipher signals are preferred in such cases. Oscilloscopes are also used to test avionics for civilian aircraft, including commercial passenger jets and business jets (bizjets). Some oscilloscopes come with software that provides eye-diagram masks, which simplify testing of serial buses used in such systems.
Navies, like air force organizations, need equipment that can successfully perform in-field naval applications like radar, navigations, and communications. This requires versatile oscilloscopes that have the capability to perform advanced waveform analysis. Such oscilloscopes will also handle repairs and calibration of an assortment of electronic equipment aboard ships and submarines, as well as onboard the Navy’s fixed-wing and rotor-wing aircraft. Some oscilloscopes have acquisition rates as high as one million waveforms per second.
Portability and LXI Access It is one thing to be a qualified technician on a battleship, or other aerospace and defense vehicle, whether on land, on the sea, or in air or space. It’s another thing to have to lug around heavy equipment up and down the platform each day to perform testing. Portable oscilloscopes can be a blessing to hundreds of defense technicians who can work without being hampered by equipment size or battery life. Better portability will turn out to be a game-changer for oscilloscope manufacturers.

An oscilloscope, or o-scope, is the best friend of an electronics enthusiast, be they professional or hobbyist. While a digital multimeter can help you measure steady state and RMS (Root-Mean-Square) voltages, theoscilloscope can not only measure peak-to-peak voltages, but more importantly provide timing information on your signal.
For instance, have you ever been working with an Arduino controlling a servo motor that has to have just the right pulse width modulation in order to spin clockwise instead of counter-clockwise? During your programming, you may have wondered just how close the pulse width was to what was needed. With an oscilloscope you can measure these pulses. When dealing with analog signals, you can use an oscilloscope to see how close you are to the frequency you need or measure what frequency you need to filter. With so many digital electronic projects, timing between signals is extremely important. Therefore, having an oscilloscope is essential.
However, price can be an obstacle. Entry-level scopes can start off at a few hundred dollars. From there, higher-end scopes can end up into the tens of thousands. However, did you know that you probably have all you need to make your own oscilloscope? In fact, you are probably reading this on a device that has the essential parts needed. All other parts are probably in your parts bin.
In essence, an oscilloscope is a data acquisition box that records the voltage from your circuit. Another device on your computer already does this: the sound card. The main differences are the level of voltage each can handle, and how fast they sample the voltage (more on that later). Since the sound card on your computer can only handle a small amount of voltage (around +/-.6V to.8V) you need to scale it down. Building your own scope probes accomplishes: allowing input of higher voltages and scaling the voltage down so the sound card can handle it.
Perfboard Double-sided, or, use regular perfboards to make your own double-sided perfboard (see Step 2).
NOTE: The resistor and potentiometer values were selected to target measurements ±10V. In fact, with these values you can probably go as high as 30V without worrying about too much current.
Note: Image one shows the output of a non-DIY bench o-scope, whereas image two and three show the output of the Sound Card O-Scope.
Note: The Sound Card O-Scope even displays what frequency it measures, which is handy for verification.
However, at 10kHz, the Sound Card O-Scope approaches its limits. Notice how the signal is jagged with angular sloping — it’s a good sign of a sampling issue.
The Hantek’s hardware is perhaps not the best quality and it lacks an AC setting and any built in filters but it can produce some fairly decent captures.
To be Continued.
Given the fact that budgets are a relative term, I though I’d add my two cents here.
I bought my first scope last year. I was planning on buying a Uscope. I liked the size, the price, and the features. I was however, concerned with the fact that it only had one channel. I figured that I’d wait till a two channel version of the Uscope came out and buy that. However, it became apparent that AES had no plans for a two channel version.
Upon the recommendation of a popular diagnostician on YT and even Paul Danner himself, I bought a used, but like new, Snap-On Vantage Pro. It had somewhat older firmware but since my newest car is a 200the coverage was fine. The cost was twice that of a Uscope but I got a two channel scope and the famous Snap-On troubleshooter as well. To me, this was a smart financial decision and I am 100% satisfied with it.
I just completed a rather challenging engine swap and without the Vantage Pro I never would have been able to troubleshoot any of the suspected problem systems. Despite the fact that it cost me twice the price of a Uscope, it easily cost justified itself during this swap.
There are numerous good reasons to buy a used Vantage Pro. Here are what I see as the most important.
First and foremost is the Snap-On component troubleshooter. Packed with information, the troubleshooter gives; troubleshooting procedures, component locations, pin outs, expected voltages and signals, sample waveforms, etc,. It makes use of an amp clamp a no brainer operation.
Secondly, and most relevant to this thread, is the fact that it is a channel scope! I’ve used mine to do cam/crank correlations, Otesting, injector testing, APP signal testing, relative compression, and several other things.
I certainly do agree with that!
I should write a review on the other scopes I have used recently the Velleman WFS2and my Owon SDS7102v………..
There certainly are numerous options out there! …..but the thread started by Tyler on Testing Injectors using a knock sensor has used up my play time.
First of all thanks for reading my article to the end! I hope you find my reviews listed here useful and that it allows you to make a proper comparison of what is best to fit your needs and budget. Don’t be afraid to try more than one product if your first pick doesn’t do the trick.
Most important, have fun and choose your oscilloscope wisely! Good luck!
