#7 Best oscilloscopes for beginners & Professionals (2023)

An oscilloscope is a device that we use to measure or analyze changes in any electrical signal, and to study the behavior of a system, within its bandwidth limits. It displays an electrical signal with respect to time, so you can see every detail of the signal i.e., its shape, frequency, amplitude, and distortion.

And because the best reliable oscilloscope is so important that from day one there are a lot of industry-leading oscilloscope manufacturers out there on the market i.e Tekpower, Keithley, Keysight, Aim-TTI, Rohde and Schwarz, and some new guys like Rigol, Hantek, Siglent Technologies, and GW Instek

Now, choosing the best beginner oscilloscopes or any level scope might be a little confusing for some guys, as there are many manufacturers, technical parameters to look for, and of course what should you pay for which feature.

And perhaps a lot of many more questions.

Here in this post, I try my limited knowledge best to help you find out the best oscilloscope no matter if you are a beginner, hobbyist, student, or professional.

Hopefully, this post will help you and you will enjoy it.

Choosing the right oscilloscope

The selection of the best beginner oscilloscope depends on a few things and parameters.

It also depends on who you are, i.e., a design engineer to diagnose operational and design problems, an automotive engineer measuring the vibrations, a repair technician, or you’re simply trying to maintain your electronic pieces of equipment.

Answering the following questions first will be very helpful.

• For what situation do you need a scope i.e., where are you going to use it? For example on the bench, at a customer’s site, or under the hood of your car.
• How many signals do you want to measure at once? For example, how many measuring channels you will require in your scope?
• A guess of the highest frequencies you will measure with the scope. According to my opinion, you should be very sure of your frequency range to be measured by the scope. This question is very important, please pay very close attention to it. As it is directly in relation to the oscilloscope price tag.
• What are the amplitudes of your signals? In case you don’t know, leave it. It is fine.
• Are the signals you are going to measure periodic or non-periodic?

A bench scope is a little heavy and specific for more professional work at the lab. The bench scope is relatively more expensive than the rest. If you are going to use your scope in the field, or for car diagnosis, you need a portable one.

Questions you need to answer before buying any entry-level oscilloscope

We talked about the technical stuff to get ourselves comfortable to answer the following questions. I recommend, answering them very carefully.

a. How much bandwidth you will require?

Multiply your highest frequency by 5. For example, if your highest measuring frequency is 10MHz, then the ideal beginner oscilloscope for you would be one with a bandwidth of 50MHz.

For the said highest frequency you can also use a scope with 100MHz bandwidth, but it is not a good idea. Because it will cost you more money and most importantly you may end up getting a high noise floor as well. If you are thinking you are not sure about the future, you can upgrade the bandwidth if needed.

b. How much sample rate you will need?

Follow the Nyquist criterion which states that the sampling rate must be at least twice the maximum frequency that you want to measure. For example, if your maximum frequency is 10MHz then the ideal scope for you must have a sample rate of 20MS/s. Again higher sample rate will end in costing more money.

c. Analysis of random signals, to capture the random and infrequent signals or glitches?

Are your projects will involve the investigation of glitches? By glitches, I mean the small random impulsive signals that cause the sudden failure of a system.

If yes, then select the one with a high waveform capture rate and high memory depth. The high wave upgrade can be a plus point here, but it is not available, still, things are pretty fine.

d. What resolution and accuracy do you need?

With an eight-bit resolution, you can detect at best a 0.4% signal change. For applications such as audio, noise, vibration, and monitoring sensors (temperature, current, pressure), an eight-bit oscilloscope is often not suitable, so you should consider 12 or 16-bit alternatives.

With a higher resolution oscilloscope, more accurate measurements are possible.

Parameters for choosing the right oscilloscope

The following are the parameters that I think you should understand before you can judge any oscilloscope as good or bad. These parameters are not limited to just beginner oscilloscopes, you can apply it to any oscilloscope.

a. Bandwidth

Bandwidth limits the ability of the scope to measure a signal. It shows the frequency range that the oscilloscope can accurately measure.

According to IEEE 1057, bandwidth is defined as “the point at which the amplitude of a sine wave input is reduced by 3 dB (approximately 30%) relative to its level at a lower reference frequency.”

In other words, bandwidth is specified at the frequency at which a sinusoidal input signal is attenuated to 70.7% of the signal’s true amplitude. In summary, the more is the bandwidth, the more powerful the oscilloscope is, and the most expensive as well.

But a rule of thumb for selecting a good bandwidth is to have the bandwidth 5 times greater than the fundamental frequency of your measuring signal.

A very good point for beginners. If you have high bandwidth, and you are playing with a low-frequency signal, you do not get accurate results. You get a lot of noise instead of great results.

b. Sample Rate

The sample rate is the ability of an oscilloscope to how fast it can acquire the number of samples per second.

Or in simple words, it determines the amount of waveform information captured and displayed on the screen. The greater the sample rate, the more resolution it has, and as a result, you have every detail of your signal on display.

SR = 2.5*(Highest frequency in the signal)

The above equation is the Niquest criteria for sample rate. Oscilloscopes must obey this in order to be called good or the best beginner oscilloscopes. This is an industrial-adopted rule of thumb.

But some industry people also recommend a sample rate that is 3 to 5 times the bandwidth. The reason they provide is, that you need a high sample rate to see any unexpected glitches or anomalies.

In summary, the more samples you have in each period, the more signal detail you’ll capture. Let’s see what Keysight Labs have got for us about the sample rate and bandwidth.

A good point for noting down, without proper bandwidth, you will end in an attenuated or distorted signal. While without enough sample rate you will end up having no information that is very necessary to display the exact frequency, rise, and fall times of your signal. You can also miss any glitch or anomaly occurring instantly.

One important thing to double-check is the sample rate of the oscilloscope when all channels are turned on.

Typically, when multiple channels are in use, the sample rate is split up among the channels. If you are using more than one channel, you’ll want to make sure the sampling rate is still sufficient.

c. Memory Depth

Memory depth is the measure of the oscilloscope’s memory to store signals. More memory depth means you can capture signals at the highest sample rate. This is a very nice feature and a good oscilloscope must have a good size of depth memory. But it will make it costly.

The oscilloscope memory is directly tied to the sample rate. The more memory you have, the higher you can keep the oscilloscope’s sample rate as you capture a longer period of time. The higher the sample rate, the higher the effective bandwidth of the oscilloscope.

d. Waveform Update Rate

It is the time oscilloscope takes to update its screen. It is a very great and important feature to look for. Of course, who cares for an oscilloscope when it takes too much time to update its screen. As in such a situation, there is a good chance you may miss an important signal or a sudden glitch.

The high the waveform update rate (wfms/sec) is the better the chances to identify any glitches in your signal and therefore you have of course a better oscilloscope.

e. Size and cost

The one used in the lab is the bench oscilloscope. There may be people who will use an oscilloscope for car diagnoses. For such people, who carry oscilloscopes where and there, the size must be of great concern. The cost is a big issue.

But you cannot have a cheap oscilloscope with great features. It just cannot happen. Good bandwidth, sample rates, built-in wave generator, FFT, extra channels, and good memory depth are the parameters that will cost you money.

f. Number of channels

Two channels are more than enough if you are just starting with electronics. The reason is, that if you are going to use more than two channels, the extra channels are just making the scope expensive. For example, you want to see the communication of Arduino at the same time.

Two channels will be enough to see what is coming to your Arduino and what is going away from it or to see the phase difference between 2 pulse trains or any two signals.

Above are the key parameters that I think make the best oscilloscope buying guide completely. Besides these, there are features you should also take into consideration. Let’s talk about those in the following.

• Having a friendly graphical interface. There are a lot of scopes that have so ugly graphics that people find it very difficult to operate the scope accurately.
• Mathes functions including FFT.
• External triggering
• USB storing option
• Remote controlling option
• Solid-body structure
• EMI/EMC free reading
• Low noise level
• High-quality probes to reduce signal distortion

How oscilloscopes are priced?

Prices of oscilloscopes are based on many parameters but mostly on the following:

• The Bandwidth
• The Sample Rate
• Number of channels
• Memory depth
• Waveform update rate

The higher the above parameters, the higher the prices.

Famous best oscilloscopes brands

Let’s talk about brands for making quality best beginner oscilloscopes. Brand signals give feelings of trust. The higher the brand signals the more quality product you get, according to me.

There are a lot of manufacturers out there in the market. Not every one of them is good. There are some bad manufacturers as well that we need to avoid if we want to invest a decent amount of money. The following are the brands that have proved themselves in the industry over the years.

• Tekpower
• Rigol
• Siglent Technologies

• Korad Technology

• Keithley
• Keysight
• Aim-TTI
• Rohde and Schwarz
• GW Instek
• BK Precision

They are global brands and have a proven track record. I am sure if you are graduating from an engineering university you may have seen a scope from these brands in your labs.

Now, if I have confused you with too much technical stuff. Forget about the rest and just focus on the first two. The higher your bandwidth and sample rate requirements the higher you have to pay for a quality oscilloscope. And remember there is no cheap oscilloscope.

Conclusion
