The Best Oscilloscope For Precise Electronics

abc news

The best oscilloscopes allow you to troubleshoot a lot of electronic equipment whenever it’s starting to malfunction. That’s the primary function of an oscilloscope, which enables it to expand its applications throughout the years.

The versatility of this device has developed thanks in large part to our ever growing reliance towards electronics. From our cell phones, vehicles, and to machines, oscilloscopes can contribute from almost any area in our lifestyle.

What is an Oscilloscope?

Oscilloscopes are not a familiar term to most people. However, you might be surprised on how often professionals and businesses use it. To explain this device better, we’ll have to focus on the importance of electronic signals.


Let’s take your car’s electrical circuit for example. A standard vehicle model would require electricity in many areas. Some of these examples are of your vehicle’s air conditioning, headlights, signal lights, dimmers, and radio.

Now, imagine your car’s manufacturer creating this web of complex electrical circuit throughout your vehicle. Admittedly, it sounds overwhelming to create an automobile that runs off of gas while also needing electricity.

Many things can go wrong. One poorly distributed voltage or a weak frequency can create a domino effect inside the vehicle. Thus, this is where the oscilloscope enters.

It prevents small problems from getting bigger over time. Remember, when you’re handling electronics, you’re also carrying an extremely fragile item. Electricity is difficult to contain, and it can cause havoc immediately if left unattended.

What is an Oscilloscope

The oscilloscope prevents this by carefully monitoring the electricity. It’s similar to a multimeter, but instead, makes use of a graph. The figure composes two axes, mainly time and voltage.

Thus, depending on the scale and instructions of what you’re using, the oscilloscope will trace any abnormal electrical waves. You just simply need to know the electrical requirements of your vehicle or any electronic to measure it.

Other applications of an oscilloscope

Other applications of an oscilloscope

As we previously said, oscilloscopes are versatile devices. Your car’s circuit is just one of the many examples out there. Another great application to this is on gadgets. Devices like cell phones and iPods have motherboards where all the signals run through.

One weak signal can cause so many problems, especially towards external accessories plugged into its jack. So what are these external accessories? Well, the two most famous ones are easily your portable charger and earphones.

That is why some have their newly bought earphones short-circuiting. Others have chargers who have burned wirings upon insertion. You can trace down all of these to the motherboard. That is why company giants like Apple and Microsoft use oscilloscopes regularly when developing the motherboard of their products.

How can you solve malfunctions in voltages?

It is also good to invest in knowing how to solve issues. Before anything else, it’s important to remember that many technologies require different means to address electrical distortions.

Just to give a good example, let’s use a motherboard as an example. Again, you may find these motherboards in almost all hand-held gadgets. Once you place the probes of the oscilloscope accordingly, look at the wavelength on the screen.

If you see a constant motion, then that means it’s ready to go. However, when you see the waves fluctuate, then it means the voltage is uneven. The best and simplest way to solve this is to add a capacitor near the circuit where you checked it.

Capacitors are little storage spaces which store electricity by conduction. That is why capacitors have either one or two conductors while separated by an insulator in between.

How can you solve malfunctions in voltages

It might sound like a simple and quick fix. However, it’s hard to do without an oscilloscope. Keep in mind that motherboards are complex circuits that intersect a lot. Hence, not having a scope will be a dead end to solving this problem.

Types of Oscilloscopes: And other things you should consider

Oscilloscopes have developed throughout the years. That is why they now come in many shapes and sizes. Different oscilloscopes specialize in several applications, so it’s important to know what you need before buying one. Remember, oscilloscopes are pricey, so be sure to make a wise investment.

Digital Oscilloscope

The digital oscilloscope is perhaps the most famous and ordinary one. That doesn’t mean it’s cheap, though. It is because digital oscilloscopes are a high-tech twist to the previous one which is listed below.

It makes use of a raster-type screen, a significant improvement from previous models. Although it’s sleeker and more durable, the real value of it lies in information. With the digital oscilloscope, you can print, archive, and review previous readings.

It is beneficial if an anomaly happens. With a digital oscilloscope, you can easily capture, archive, and review or print for future study.

Analog Oscilloscope

Analog Oscilloscope

Analogs are one of the first modern oscilloscopes to be developed. The models of these types are typically older. The reason for this is because less and fewer companies are using analog circuits.

However, if you only need to examine a bunch of devices that have analog circuits, then this scope is good enough. Not to mention, it’s cheap compared to the digital. However, you won’t get some of the digital’s perks such as analysis, data storage, and advanced displays.

Cathode-ray Oscilloscope

Cathode-ray scopes, or more commonly known as CRO, are the smallest oscilloscopes between the three. Unlike the previous two, cathode-ray oscilloscopes have a design like a gun or a flashlight.

Thus, it looks much more portable compared to its other counterparts. However, it’s also important to note that some cathode-ray oscilloscopes are designed similarly to the digital and analog versions.

This oscilloscope got its flashlight design out of the very definition of a cathode-ray. Simply put, cathode-rays are electron beams which a tube-like vacuum releases, similar to how this oscilloscope works.

Our Top 5 Picks

  • The unit comes with a 220V cord only.

Our Verdict

If you’re just a hobbyist, it is important to consider that you don’t have to buy the one with the most channels or higher MHz. You can even opt to purchase an analog or second-hand oscilloscope if you know what you want or need from your equipment. However, based on several reviews, Tektronix might be a good option to begin the whole process.

Still, buying the best oscilloscope will boil down to its precision and added features. Good luck with your electronics and be sure to keep your scope well-calibrated!
