The oscilloscope (o-scope) is a technical instrument, a measurement/scanning/tracking system that monitors and depicts electrical waveforms on an LCD. The primitive oscilloscope models used to be analog devices. Nevertheless, as technology advances too rapidly, most o-scopes are automated/digital nowadays.

Most scopes create a 2D graph on the X-axis with time and on the y-axis with voltage. You will display the production according to your convenience with the controls on the front of the tool. They encourage you to change the monitor, scale both vertically and horizontally, zoom the display, concentrate and steady the signal, etc.

Why do you need an oscilloscope?

Wherever the voltage and frequencies require continuous control, the first instrument you need is a scope.

Oscilloscopes are used in a broad variety of environments for examining, calculating and tracking. It is challenging to choose the right oscilloscope, but we have outlined to you some of the characteristics and specifications that it should have.

Computers are used by the most modern o-scopes to process and view waveforms. These computers may use every kind of monitor – CRT, LCD, LED, OLED and gas plasma. There are literally hundreds of various o-scopes to choose from.

That is why this guide was compiled – to assist you when you need to buy the best oscilloscope for diagnostics of a car or any electric device. Make sure to read the comparison table and buying guide with tips for beginners.

The Buyer’s Guide

Such scopes are stronger than other scopes. Any criteria are much stronger than others are. Some functionality helps you define how well a range may be assumed to function. When picking an oscilloscope, it’s often necessary to remember the following factors:


1) Analog devices

The analog oscilloscope is the device where measured voltage will show on the in-built computer. This voltage has the job of deflecting the current, and a waveform is then automatically obtained.

2) Digital oscilloscopes (DSO)

A digital oscilloscope completes the entire phase highlighted above, unlike the analog o-scope. Also, it applies an analog-digital converter to receive digital data until the waveform is collected. This data is then used to recreate the waveform on the screen, such that both the analog o-scope and the DSOs are basically outstanding for viewing the electrical signal. Even, the second helps you to recreate the message later, unlike the first.

Compared to analog devices, all DSOs can offer such benefits: 

  • Portable and lightweight;
  • The highest bandwidth range;
  • Colored displays with high resolution;
  • Printing and storage features;
  • User-friendly interface;

Modern DSOs may also be entirely implemented into Automated Test Equipment (ATE) systems with their PC networking. Moreover, the DSO is also used as the front end of a device for the acquisition of high-speed data, rendering the expense per channel far more economically feasible.

3) USB-based devices

It is still a digital oscilloscope, although the only distinction is that this oscilloscope will now be used to display your PC’s data with the required USB cable link.

In certain instances, o-scopes with USB connections do not also have a monitor since the data is shown directly on the PC. This variety favors a lower cost that undoubtedly satisfies many that do not pursue professional goods. Sometimes, USB oscilloscopes have very restricted input voltages.

There are also small (portable) and PC oscilloscopes. Choose the size according to your tasks and requirements. 


The key attribute of an oscilloscope can be bandwidth, so when considering it, you would have to be cautious. The o-scope can go to this maximum frequency limit. The high-bandwidth oscilloscope, of course, is the stronger model.

In terms of oscilloscope bandwidth, there is a law. It’s called the Fifth Clause. The bandwidth of your o-scope must, according to this, be at least 5 times the maximum frequency at which you can operate.

This is the most significant spec when purchasing an oscilloscope that you can pay heed to. Bandwidth describes the frequency spectrum that can be reliably calculated by o-scopes, and is commonly measured in Hertz and, more precisely, Megahertz.

In order for you to get the most precise calculations, the recorded bandwidth of the scope should ideally be five times greater than the maximum frequency of the signal.

Megahertz scores of 50, 100, or 200 can be used for o-scopes, while specific gear can go as far as 1 gigahertz. Assuming the value is not a concern, you can recognize the signals you want to analyze to get the right power for bandwidth that ensures that you will get readings that are available.

Number of channels

You’ll have to equate two or three signals often. Only when your system has two or more channels will you do it. Many scopes will interpret more than one signal at a time, simultaneously showing them all on the computer.

A separate channel is fed into any signal read by a scope. The signals are therefore seen side by side and can be contrasted easily.

Because of this fact, o-scopes with more channels appear to be more costly, so this can also weigh into your decision when choosing whether you need to show two or four signal channels.

Sampling rate

This is similar to film signals at fps. It determines the quick framing of the electrons on the screen. The higher the rate of sampling, the greater the detail and efficiency. Although, if you have more than one channel concurrently, the output will decline as the sampling rate will then be distributed evenly between the channels.

Rise time

A scope’s defined raise period determines the fastest growing pulse that it can calculate. The rise time of a scope’s expansion is quite strongly linked to the bandwidth.

In deciding the precision of the specifics of your signals, the period of increase is significant. Faster uptime ensures measures that are more precise and fewer mistakes.


The memory of all the o-scopes is used to save the samples. A PC would have to clear it until the memory is complete and resume at the beginning, which will have a detrimental impact on your job.

That’s why models with plenty of memory or models that endorse memory expansion should be selected. Note: this function is generally referred to as the depth of memory.

Memory depth is what it looks like, whether it is in the scope itself or from a linked memory or SD card, the volume of data that the o-scope is able to save.

The more you can store, the more you need to evaluate, which is useful when looking at a signal to identify irregularities or other adjustments across a larger time span.

If you expect that you may need to process signals over a long period of time then you will need to purchase items with a higher memory depth.

Screen quality

Because it is the gateway to check the results of the o-scope, the screen size and resolution may be significant. Many of the displays are about seven inches, however, assuming that you’re working for an average-sized device, smaller o-scopes are going to be smaller, naturally.

Accuracy and resolution

A signal shift of 1 percent is typically no concern in visual technology, but in audio electronics, 0.1 percent distortion or noise can be a tragedy. Most modern DSOs (digital o-scopes) are designed for fast digital signals and provide 8-bit resolution (8-bit ADC) only, so a 0.4 percent signal shift can be observed at the best resolution.

The voltage spectrum is broken into 256 vertical phases (28 = 256) with 8 bits. This correlates to around 8 mV per phase, with a ±1 V range selected. This may be sufficient to display digital signals, but leave much to be desired, particularly when utilizing the feature of the spectrum analyzer, to view analog signals (if it has any).

An 8-bit oscilloscope is sometimes unsuitable for applications such as audio, vibration, noise and measuring sensors (current, temperature, pressure), and 12 or 16-bit alternatives should be considered.

High resolution (12 bits or more) and high DC accuracy oscilloscopes are often referred to as precision o-scopes.

Waveform update rate

This is the period it takes for oscilloscopes to refresh the screen. It is a really nice and significant trait to search for. Who cares about an o-scope, of course, when it takes too long to refresh the PC. There is a fair risk that you could overlook a significant signal, as in such a case.

Compatible probes

Any o-scope and the probe function work as a single system, so when choosing this device, make sure to remember the probes. Probes actually become a part of the circuit during calculations, adding resistive, capacitive, and inductive loading that changes the calculation.

It’s better to use probes that are optimized for your scope to mitigate the impact. Choose passive probes that have appropriate bandwidth. The bandwidth of the probe needs to equal that of the oscilloscope.

Major types of probes:

  • Passive probes are the most common probes used for every input channel. They are required for ground-referenced measurements;
  • High-voltage probes are accurate and floating when it comes to differential measurements;
  • Logic probes will recognize and transfer digital signals form a mixed signal o-scope;
  • Current probes are used for measuring current and instantaneous power;

Triggering feature

Edge triggering is provided by all o-scopes, though most provide pulse width triggering. Look for a scope that provides sophisticated activation on more difficult signals to obtain abnormalities to allow the full use of the scope’s record duration.

The broader the number of trigger options available, the more responsive the range is. Look for the devices with such features:

  • Logic triggers;
  • Serial data triggering;
  • Video triggering option;
  • Pulse/digital triggering;

Tips for buyers:

  • If possible test a few o-scopes before buying. Opt for the online sales where the manufacturers offer the money-back guarantee;
  • Get demos and samples for a certain device. Make sure the demos feature the true signals you want to test with higher cost scopes, not just signals that display the scope in a positive light;
  • Ask about the upgrades when purchasing a scope, and check what is included in the cost. Be sure the program is included and ask if you would have to compensate for software updates for PC-based scopes. Testing the cost of cables and applications to attach to PCs/printers for benchtop scopes will add 50 percent to the overall cost;
  • Verify the duration of the warranty. If your device fails to use, the manufacturer should cover the repair costs;

  1. I had both Rigol DS-1054Z and Siglent SDS1104X-E. I want to share my mind about these oscilloscopes.

    For the period I use Siglent SDS1104X-E as my main scope, I found it is well made for this price. Build quality is good. The light is excellent. Out of box calibration are good enough for most of us. It’s more than enough for the typical hobbyist. It has all the critical features one might need in day-to-day use, even on a moderate budget.

    On the other hand, Rigol DS-1054Z has a slightly different look/feel when compared to Siglent SDS1104X-E, but both are great for their price. One can see it is well made with the good build quality at this price range.
