How Oscilloscope Works

what is an oscilloscope used for

An oscilloscope is a device for displaying varying voltage signals graphically, usually in the form of a calibrated diagram of multiple signals. After the waveform is displayed, its properties such as amplitude, frequency and so on can be analyzed. It uses the time-domain method of displaying changes in electrical signals that have passed through it. They are commonly known by different names, including CRO and DSO, which have evolved from measuring voltage changes over time based on events.

An oscilloscope is an essential lab instrument. This instrument is used for measuring voltage, current, frequency, and power. In this blog post we will discuss how oscilloscopes work and what they are used for today.

What is an oscilloscope?

How Oscilloscope Works

In school you probably made charts, and you probably saw them in the newspaper as well. These graphs often illustrate how the value of a quantity over time varies, such as a heart rate, the price of stock, or a nation’s exchange rate. Y-axis represents the quantity plotted vertically, and x-axis represents the period plotted horizontally. If you didn’t have an oscilloscope, you may find that charts like this take a long time to plot. You can feed oscilloscope signals from probes attached to electronic circuits, scientific instruments, or medical monitors to draw charts automatically.

What can we use oscilloscopes for?

It is possible to use an oscilloscope for observing signals in all sorts of ways. In electronics courses, oscilloscopes will be used to monitor the changes in circuit signals over time. They can also be used to troubleshoot TVs, radios, and much more. Coaxial cables are used to connect the probes of a typical oscilloscope to electric currents, but this does not mean oscilloscopes can only measure electricity. You can use an oscilloscope to measure almost anything when you attach a transducer (that converts one type of energy into another). Among the various types of transducers that can be used to study sound signals with an oscilloscope are microphones (which convert sound energy to an electrical signal), thermocouples (which measure temperature changes), or piezoelectric transducers (which generate electricity when squeezed).

What makes oscilloscopes so useful is their ability to visualize and comprehend invisible signals. Ultrasound is above human hearing threshold, so by definition, it cannot be heard by humans. However, if you use an oscilloscope, you can see it easily and study it. The oscilloscope, on the other hand, offers the possibility of seeing and studying sounds in a way that may not otherwise be possible for those with hearing impairments.

How an oscilloscope works

Despite their innumerable similarities, oscilloscopes are almost exactly the same as traditional televisions. Often, oscilloscopes are referred to as cathode-ray oscilloscopes. The back of a TV screen is coated with phosphors that make electron beams scan across it back and forth. The phosphors illuminate when the beam strikes the screen. Electron beams sweep across the screen in less than a blink of an eye and build up the picture you see. Afterwards, it’s the same thing all over again. Once more. Once more. so, Instead of seeing a still picture, you see a moving one.  Oscilloscopes work in much the same way except that the electron beams draw graphs rather than pictures. What you are really seeing when you look at a line on an oscilloscope screen is the wobble of an electron beam!

One thing to keep in mind is that, what appears on your on-screen chart depends on the signals transfer into the x and y connections. Traditional oscilloscopes are analog devices because they correspond one to one with these two things. Alternatively, we could say that the trace on the screen is an analogy of your object of study.

Types of oscilloscopes


Cathode-ray tubes (CRT) were used to create oscilloscopes, as we already learned. Its bulk, weight, power usage, unreliability, and cost make it an unattractive investment. The CRT television has been increasingly replaced by LCD technology, which is more convenient. So, CRT oscilloscopes are almost all being replaced with flat-panel LCD screens. As opposed to older oscilloscopes, LCD oscilloscopes draw traces through digital electronics instead of moving electron beams — effectively mimicking what happens when using the older technology. It is generally cheaper and more compact to use LCD oscilloscopes.

The traditional oscilloscope makes use of entirely analog technology. You can feed them signals, and they will display them on the screen in accordance with what you input. The LCD oscilloscope is usually a digital oscilloscope. Analog signals are converted into digital form by analog-to-digital converters, then the numbers are plotted on the screen.

Plugin (USB) oscilloscopes

Computers, tablets, and smartphones already come with CRT or LCD displays, so buying the best usb oscilloscope is no longer necessary for occasional hobby uses. Many companies sell affordable oscilloscopes for mobile devices that plug into USB ports or have equivalent leads. You can use a PC or mobile device as an oscilloscope if you have one of these programs. It’s great to have that option!

How Oscilloscope Works

Analog oscilloscope

Let’s take a look at how analog oscilloscopes work. Here is a block diagram that shows the process easily. Let’s have a look at the diagram and read the full description to know how analog oscilloscope works:

how oscilloscope works

Analog oscilloscope block diagram


Your circuit under test is connected to this piece. Oscilloscope measures the difference between two points (voltage) with probes that typically have two tips each.


It is often necessary to amplify (increase in amplitude) or attenuate (decrease in amplitude) an electrical signal before it can be sensibly displayed to the user or without damaging the oscilloscope’s inner circuitry.

Trigger System:

Triggers determine when the oscilloscope begins displaying waveforms based on a user-defined condition (such as a voltage threshold). It can be extremely useful when finding intermittent pulses in a circuit or when synchronizing the display to regular patterns like sine waves so that the pattern remains steady on screen.

Sweep Generator:

Sweep generators create sawtooth voltage patterns in order to control the horizontal plates in CRTs. With this technique, the beam of light moves from one side of the CRT to the other. The  sweep generator can be set to produce a certain frequency and triggering.

Horizontal Amplifier:

The horizontal amplifier, which can control the horizontal plates in the CRT, is much like what was found after the probe. It enhances the sawtooth wave from the sweep generator to control the amplitude of the horizontal plates.


A phosphor-coated screen is illuminated by an electron gun that continuously fires electrons onto it. The beam is deflected by two sets of plates. Using the probe voltage, the vertical plating is controlled directly, and using the sweep generator, the horizontal plating is controlled. A solid line is shown on the screen when the beam rapidly deflects. As the probe voltage varies over time, this line on the display shows it.

Digital Oscilloscope

In the 1980s, Nicolet manufactured the digital oscilloscope (DSO) by utilizing a relatively slow  analog-to-digital converter (ADC). Digital oscilloscopes have become faster, smaller, and more popular as digital technology has advanced.

Digital Signal Processors are essentially sophisticated computers fitted with high-end analog to digital converters. Although there are many similar functions and features to those found on older analog oscilloscopes, there are also some that are new.

Let’s have a look at the diagram and read the full description to know how Digital Oscilloscope works:

how oscilloscope works

Digital Storage Oscilloscope Block Diagram


In order to test your circuit you need an oscilloscope that can measure the voltage between two points. The tips of most probes are attached to different nodes on your circuit.


In oscilloscopes, electrical signals are amplified or attenuated by circuits. This will allow for an effective display and will prevent damage to internal components.

Trigger Select:

Most oscilloscopes can display waveforms triggered by either an internal or external signal (from another source).

Control Logic:

An opportunity for a user to adjust signal capture and display logic. Analog oscilloscopes have horizontal controls that are analogous to the controls on the control panel, but they offer more options.


A sampling rate is determined by the control logic of the analog-to-digital converter. Binary numbers are created from these samples and then stored in memory.


In memory, sampled signals are represented by digital data. Using this information, a graph representing a close approximation of the original electric signal can be generated.

Time Base:

The horizontal axis on the display is controlled by the time base as set by the control logic. The  user can adjust the time base based on a single trigger point to capture sporadic signals or to hold periodic signals, such as sine waves, steady on the display during a period.


An oscilloscope displays waveforms on a screen by combining memories with time bases and displaying waveforms from memory. Waveform in which voltage and time are represented as Y-axis and X-axis, respectively, often represents the sampled signal. In older DSOs, CRT displays are used as displays, but most modern DSOs use LCDs.

The Evolution of Oscilloscopes

The oscilloscope has evolved into a smarter, more powerful piece of test equipment since their invention. PC-based oscilloscopes are highly portable and analyze and display waveforms with the processing power of a computer. A digital phosphor oscilloscope (DPO) can display a signal’s frequency-of-occurrence in a manner that mimics an analog oscilloscope.

Logic analyzers specialize in displaying digital signals, which are made possible by oscilloscopes. The mixed signals oscilloscope (MSO) is the result of combining these two powerful instruments. Analog signals can be displayed on MSOs just like oscilloscopes, while digital signals can be analyzed like logic analyzers.


What is the working principle of oscilloscope?

Voltage can be measured with an oscilloscope. During this process, a small current is drawn in order to measure the voltage drop across a resistor. Using an electric field, the voltage drop amplifies and deflects the electron beam either in the X (horizontal) or Y (vertical) axis.

What is the purpose of an oscilloscope?

With an oscilloscope (or scope), voltage signals are tested and represented as waveforms. Graphs are used to show the change in signals.

What are the major components of oscilloscope?

Oscilloscopes have three main parts – the horizontal system, the vertical system, and the trigger system. The oscilloscope is able to reconstruct signals accurately based on the contribution each system makes. Oscilloscopes have three distinct front panels branded  Vertical, Horizontal, and Trigger.

Is an oscilloscope necessary?

It is true that oscilloscopes are primarily used for measuring electrical waveforms. Furthermore, it also has a pretty high degree of accuracy for measuring mostly constant voltage levels. Moreover, it can detect small fluctuations in battery power, which is not possible with most multimeters.

Why are oscilloscopes so expensive?

The oscilloscope is a precision instrument. To ensure they meet standards, they must undergo strict quality control. As a result, costs continue to rise. In addition, higher bandwidth means higher costs.


It only took a few decades for the oscilloscope to evolve from its early days as an analog instrument that could do very little more than display voltage and frequency, into a sophisticated device with PC-based capabilities. These modern devices can process waveforms at speeds of up to 300MHz, which is much higher than any analog scope ever created.

There are even digital phosphor oscilloscopes (DPOs) on the market today that mimic the appearance of their predecessors but have all of this power behind them. If you want to learn more about how these instruments work or what types exist, let us know!

Siglent Vs Rigol

siglent vs rigol

Siglent and Rigol are staple choices of brands when looking for a premium oscilloscope that won’t disappoint. They both create almost similar devices with good learning curves, a broad spectrum of applications, high precision measurements, automatic and manual operation modes, HD screen resolutions, and many more.

However, when choosing, you may only need to part with some dime for a single device. As such, it becomes a bit daunting to know which brand wins in the tussle of Siglent vs. Rigol oscilloscopes. In this comparison, we’re going to cover all the features that set each brand apart, similarities, and differences.

In case you’re in a hurry, you can jump onto the conclusion part of this article for a glimpse of our preferred choice. We also show the metrics we’ve considered to come up with the verdict.

Siglent Vs. Rigol Brief Analysis

Siglent and Rigol oscilloscopes share myriads of similarities. If you’re a beginner in the circuitry industry, it is normal to confuse which brand to choose. For decades, those who’ve been in the industry cannot differentiate and select the best model between the two.

To be pragmatic, every Siglent model has an equal Rigol competitor. Only a few design tweaks can weigh out, but the two will almost be the same on functionality. So expect this competition to be a stiff one with a lot to take into account.

To understand the two brands, it is best to consider their originalities and a brief history. Well, Siglent is a European brand founded in 2002. This company has developed over the past one and half decades to become a renowned electronic creator that also makes DC power supplies, multimeters, and waveform generators.

Siglent has branches and outlets across the globe. It is the top producer of oscilloscopes in China and the Asian world as a whole. Almost 15% of the brand’s annual revenues go into R&D technology support programs. Siglent products are among the topmost creative devices you’ll ever find in the market, so is the SDS1202X oscilloscope.

Rigol, on the other hand, is a Chinese brand founded in 1998. The company has its headquarter in Beijing, China, and several branches and outlets across the globe. This brand also manufactures waveform generators, spectrum analyzers, RF signal generators, multimeters, and oscilloscopes.

Rigol is one of the electronic device producers that are always on the trend for new and more advanced creations. The brand currently has more than 493 patents. It prides on developing the RSA5000 real-time logic analyzer and a wide range of top-notch oscilloscopes, including the Rigol DS1054Z.

Siglent Vs. Rigol (side By side comparison of their features)

Siglent SDC1202X-E200

This oscilloscope comes in a rectangular body with two stands attached at the base for support. The outer surface is finished in a grey shade that gives it the appeal it deserves. The brand has used a dark-colored hue for the screen that enables the oscillating waveforms to show effortlessly, even in the dark.

Just below the screen are menu buttons and the ON-Off power button. The farthest left, below the screen, is also a USB port for connecting the device to any electronic device you’d wish to test voltages on.

The right side of the oscilloscope features navigation buttons that you can use to initiate, run, and fluctuate triggers. The top part contains controls for selecting and adjusting intensities, clearing sweeps, saving and recalling sweeps, displaying measurement, modifying cursors, printing results, and a lot more. You can as well run or auto-stop the triggers using the two buttons at the farthest top-right corner.

The middle buttons are for variables and math functions. You can use them to adjust the depth of your waveform either vertically or horizontally. The trigger buttons at the middle, farthest right, applies whenever you want to set up either single or double channels when triggering.

At the bottom-right side are three ports for X, Y inputs, and an extension. You can use these ports to connect the device to the grid.


Rigol DS1054Z is a rectangular-shaped oscilloscope that features a grey color for the body. It comes with two stands at the base to augment its bench-top body style. The screen is striking dark to allow for easy peaking of the waves as they form.

Unlike the Siglent counterpart, this oscilloscope comes with its Primary menu buttons located at the farthest left, lining vertically. Below the six buttons are the ON-OFF button and a USB port for connecting a secondary device. The screen below is an empty groove that serves as a cherry top to its design tweaks.

The navigation buttons line on the right side, with the top part featuring clear, auto, run/stop, and single-channel tabs. The middle-right buttons for REF and Math functions and 4 CH buttons for running advanced algorithms: the Menu, Mode, and Force buttons line to the farthest right on the middle right.

Lastly, at the bottom of the navigation buttons are four CH ports for plugging CH and power cables. Each port has a description of the cable it accepts to eliminate any confusion when using.

  • Number of Channels

The competition of Siglent Vs. Rigol cannot be complete without mentioning the number of channels each has. Well, Siglent SDS1202X-E200 comes with two channels, with a button that you can use to initiate and run only one channel.

Rigol SD1054Z, on the other hand, comes with four channels, with a button that you can use to run only a single track. For higher scopes of functions or use on multiple devices, this model is your go-to.

  • Screen Display

Siglent  SDS1202X-E comes with a large-7 inch screen display that is sizable enough to capture two waveforms. The TFT-LCD display uses the ultra-high-definition 800 x 480 resolution. It is bright enough for use even in the dark.

Similarly, Rigol DS1054Z features a 7-inch screen display that supports four waveforms simultaneously. It leverages the 800 x 480 screen resolution so that you can be sure of an oscilloscope bright enough for use anytime.

  • Bandwidth

Siglent SDS1202X-E has a bandwidth of 200Mhz. It is one of the few oscilloscopes in the medium category that will guarantee you a detailed measurement. Even more, it supports the 1gsa/use sampling rate, making it very accurate and ideal for all tasks that require precision measurements.

Rigol DS1054Z, on the other hand, has a bandwidth of 50Mhz. The bandwidth and the channels are analog. As such, it is not better placed to guarantee accurate results in precision measurements.

  • Boot-Time

If you’ve ever used devices from both Siglent and Rigol, you’ll concur that Rigol devices boot faster than their Siglent counterparts. On average, Rigol’s advanced devices boot in less than 10 seconds, while Siglent’s take up to 30 seconds to start.

However, how fast your device will boot primarily depends on its period of use and the state of its inner components. But even with that, you will never go wrong with the Rigol DS1054Z if boot time is one of your critical concerns.

  • Price

Siglent SDS1202X comes with a $379 on Amazon. You’ll also need to pay shipping fees and import charges. Nevertheless, this price tag is susceptible to fluctuation. So it can go higher or lower over a certain period.

Rigol DS1054Z features a $349 price tag on Amazon. Additionally, you have to spend on shipping costs that vary depending on your country. If you intend to cut the cost corners, this model will warm your heart as it is less expensive.

But even with that, its price is a steal when you factor in the scope of functions it can undertake; we have no choice short of crowning it the winner in the tight race of Siglent Vs. Rigol

Angled vs Straight Spotting Scope

angled vs straight spotting scope comparison

When it comes to hunting, you would require a specific type of specialized gears. The same thing goes for birdwatching too. Among all of the specialized equipment, the spotting scope is the most important.

No matter which application you intend to use the scope for, a high-quality unit is a must. Without getting one of the quality ones, it would be quite difficult for you to identify and spot distant targets.

And when people consider buying one of these, they tend to put angled vs straight spotting scope against each other.
And we are here to make things easier for you so that you do not end up scratching your head when it comes to choosing one of them.

Angled vs Straight Spotting Scope Comparison in 2021

Angled Spotting Scope Reviews

First, let us talk about the angled spotting scopes. Just like the name suggests, these are angled. And the curvature takes into full-effect in the eyepiece area. Now, you might ask, why would a scope be curved in that region only? Well, that curvature has some advantages to offer.

First of all, it will enable you to change your viewing angle, which can come in handy in the case of spotting targets that are farther away from you. It can also make it comfortable for you to view your targets that are in hilly or mountain areas.

Secondly, it will do the same thing when it comes to looking directly downhill. You will be able to position the scope to the angle that you prefer and have a comfortable overall viewing experience.

Besides just coming in handy in mountainous areas, these offer a redefined viewing experience in straight regions. No matter if your target is on the ground or in the sky, you will be able to track it efficiently with this.

Straight Spotting Scope Reviews

Straight Spotting Scope

As you can guess, these scopes are straight. These do not have any curvature on the body, nor will they have any angled design. They are most likely to have a one-piece construction, which would be made from a single tube. Many people even refer to them as telescopes because of the straight design that they feature.

And just like telescopes, you would require a tripod to make them sit at an appropriate height. Without tripods, getting an adequate viewing height for these would be pretty tricky.

Nevertheless, these are most comfortable when you are in a prone position. You would not have to raise your head that much while staying at prone with these.

However, they do provide the capability of quickly acquiring your target. Many of them also have different adjustability options to make it easier for you to switch between near sight and far sight tracking.

Recommended Straight Spotting Scope Reviews

Not all of the straight spotting scopes you will stumble upon will offer you a redefined target tracking experience. For your convenience, we have compiled a shortlist of the ones that will offer you that experience. They are as follows:

Angled Spotting scope or Straight Spotting Scope?

Even though both of the spotting scopes are used for the same purpose, there are some differences between them. The major differences are:


It goes without saying that the design of both the scopes is different. While one of them has a curved design, the other one has a straight design. Even though the design difference might not seem that drastic, but that is what differentiates both of them in the first place.


In comparison, the angled scopes are more stable than the straight ones. Even though you would have to use a tripod for both of these, the angled one can sometimes be used without a tripod. Yes, it is that stable! And after putting a tripod under it, it will be more stable even if there is a strong wind.

Target Acquisition

If both of these are put against each other in the case of target acquisition, the straight one would have the edge over the angled ones. They are easy to use, and adjustments can be made almost instantaneously. So, you will be able to acquire the targets quickly and easily.

Sun Shading

The straight ones have better sun shading in comparison. As there are no angles, your eye would rest with the eyecup directly. Because of that, the lens would be more protected from sunlight. Thus, there would not be that much glaring and reflection issues with these.

What to Look for in an Oscilloscope

While looking to purchase anything, be it a machine or any home equipment, there’s always a list of things to look for. Good automotive oscilloscopes are pretty hard to find, given the solid criteria list. The number of things you need to check before grabbing one is mentioned here.

Input Channels

Always check how many channels the tool has. The flexibility, as well as the accuracy of the channel, is very crucial to get your preferred results. The more input channels there are, the more you can compare and read.


Much like choosing a Wi-Fi, this is an important fact for choosing a scope. Always remember that the highest bandwidth isn’t always the best. Often times the noise gets increased along with the bandwidth since it detects a lot more than is needed.

Your desired width should be twice the maximum frequency of the signal being transmitted. For higher frequency, higher bandwidth is needed.

Rate of Sampling

This particular point determines how many lines and details of the waves can be recorded and stored by the device’s analyzer. The more points a wave has, the more accurately it can be displayed.

It’s quite like image resolution, the more pixels, the better and sharper image. If your chosen item has a sampling rate that’s five times more than the frequency input, it’s going to get the job done with no problem.

Health Navigation

Ok, so even after you’ve got a scope with a great memory and amazing reading capacity, if you can’t navigate the graphs and zoom them in to check, the purpose is lost.

For evaluating what you found, you need to be able to zoom in and take a good look. So look out for good navigation features and proper zoom capacity. You need to be able to select the proper part of the axes to analyze, right?


The scope you need is one that has at least one probe (preferably two) to be of convenience for you. If probes are included in the set, you don’t have to go around looking for suitable ones to match your measuring intent.

In the case of probes, watch out for digital ones that are more suitable for parallel bus types. There’s a variation of probes today – handheld and portable to soldering ones.


This is a big word in the world of oscilloscopes. The triggering of the scope is everything that sets it apart from an average machine. You need to know what you’re looking for and what situations can trigger the device.

But what is triggering actually? It’s basically the starting point of signal acquisition for a certain event. There are both hardware and software triggers. Look for how much you can specify the trigger and its transition zone.

Connectivity and Operation

Does the product come with proper and supportive instructions? Is it easy to use? Since not everything can be known from a manual, and it’s difficult to operate a machine that’s not at all intuitive, look for ones that have basic user guidance built-in and straightforward menu options.

Also, look for whether or not a dashboard is possible as it lets you compile and evaluate tasks in a personalized interface. If you are getting a very pro-level scope or if you lack experience in working with scopes before, it’s good to get one that offers online interactive help.


Finally, look at the connectivity of the device. Does it have Bluetooth? Is it suitable for connecting to your Windows and PC? The factors like the programming interface, printer connection, and data transfer to MS Excel or Word is definitely something to keep in mind while buying one.

Frequently Asked Questions

Here we have some of the most commonly asked queries regarding oscilloscopes:

Why should I use an oscilloscope?

If you troubleshoot or work with electronics at high speed, you need to use one. Using these, it’s possible to figure out what’s wrong with a particular device and whether it is working correctly or not.

How many types of oscilloscopes are there?

There are mainly two types – digital and analog oscilloscopes. But going more into depth, there’s a lot more – around five different types to be precise. You’ll find the cathode ray scopes, dual-trace, and mixed-signal scopes. There are DSO scopes that are more common nowadays.

What does triggering an oscilloscope means? And how do I do it?

Triggering an oscilloscope means having it pick up signals from a certain point in a certain circumstance. You can do this by using a switch in most cases.

Oscilloscopes for auto-use have triggers that are both internal and external inputs. Almost all scopes have an external triggering input, and you can choose how the triggering should take place.

Which components are involved in measuring and reading?

The main elements of the device involved in reading are the cathodes and anodes present. There’s also a light-emitting layer and a point that detects waves. These machines contain a wheel cylinder that detects the brightness of the screen, and thus, the reading gets done.

Final Words

Your car is an extension of yourself on the road, and quite naturally, it’s precious. So it deserves the best treatment. And for that, you’ll definitely need to get one of the best automotive oscilloscopes to make sure it’s working like a breeze.

What to Look for in a Best Digital Oscilloscopes

Now that you have a list of some of the digital oscilloscopes, it is time to know more about each feature. Knowing the reason and usage of these features will help you decide.


The higher the bandwidth, the better the output. So, if you have big projects and multiple signals, then choose a product that has at least 50 to 100 MHz bandwidth. Digital oscilloscopes tend to have more than or equal to 50 MHz anyway.

Size and Structure

You can buy mini oscilloscopes, desktop oscilloscopes, or regular oscilloscopes; the options are endless. So, depending on your work, you can go for any of them. However, you should know that a mini oscilloscope will have slower output, but they will be compact.


Channels are vital for oscilloscopes. It determines whether you can do two jobs at a time. So, if an oscilloscope has only one channel, it is better to avoid that product. Moreover, some brands will also allow you to process both analog and digital signals. So, you get more versatility with one product.

Sampling Rate

The rate at which the device captures each signal to form a wave is the sampling rate. So, naturally, a higher sampling rate means faster output. However, oscilloscopes that are smaller in size will have a lower sampling rate.

So, if you do not want that, go for regular oscilloscopes. Also, memory capacity determines how fast the sampling happens. If the capacity is more, then the visuals will stay on the monitor for a long time.


Digital oscilloscopes have a range of displays. You can get color displays, trigger displays, and even cursor modes. So, based on your needs, you should purchase the oscilloscope. However, always keep an eye for the resolution. If the screen resolution is terrible, then analyzing will become difficult.


There are multiple ways of connecting the oscilloscope, but wireless modes are LAN or Ethernet. However, these connections can have unwarranted disturbances. On the contrary, you can use USB cables as well.

Frequently Asked Questions

Below are some of the most commonly asked queries regarding digital oscilloscopes:

Analog vs Digital Oscilloscope: Review and Comparison

oscilloscope analog vs digital channels

Be it for work, education, or as a hobby, a good oscilloscope is the basis for accurate voltage wave measurements. As companies are exploring and adding different features, it may be difficult for even the expert to make a firm decision.

The first place to start is deciding which version of an oscilloscope to get. We are here to help you make that decision through this analog vs digital oscilloscope comparison.

While some may argue, there is no right answer to which one is better. Everyone has different reasons and opinions. So, we leave it up to you to make the decision at the end.

Analog Oscilloscope

Analogs are the first-ever oscilloscopes to exist. They typically have a CRT or Cathode Ray Tube screen. It displays the waveform and images to help identify the faults in the electronic.

The screen shows the signals in an X and Y axis; with the X-axis representing the waveform and the Y-axis representing the voltage.

Because of this, the screen displays a horizontal pattern of waves. Analog oscilloscopes are cheaper, making them suitable for general people to buy.

They are also typically bulky, although modern analog ones have LCDs and lighter components to make them more portable.

Analog Oscilloscope or Digital Oscilloscope?

Although they both work the same way and have the same purpose, we have found some of the major differences between the two types of oscilloscopes that set them apart.

Features and Functions

One of the most apparent factors that is different between them is the number and variety of functions you can get in a digital oscilloscope, compared to an analog.

However, even with fewer measurement functions than a digital one, some analogs give pretty accurate results. Some even work better than digitals.

That being said, people do prefer the digital version more because of its wide number of functions and flexibility.

It also comes with a software bundle, which the company can update to add more features or fix bugs etc. for fewer errors. This is something analog oscilloscopes don’t have.


The major difference between the two, and possibly what sets them apart, is the waveform. In case of an analog oscilloscope, you can see the original waveforms.

On the other hand, digital oscilloscopes use analog channels, so they show analog waveform. However, these waveforms get converted into digital numbers via sampling.


Digital oscilloscopes, having more functions, are pricier than analog ones. Most digital oscilloscopes in the market cost around or over $1000.

They also offer the highest quality and accuracy of results. But there are some exceptions, such as the ones on our list.

Likewise, analog oscilloscopes are economical and generally cost way less than the other. There are some costly ones, but you can typically find a good one at a reasonable price. But the digital version, understandably, outdates the analog in the current market.


Although there are significant differences between the two, they are both great in their own way. We hope that we have helped you to make your decision with this analog vs digital oscilloscope article.

How to Connect an Oscilloscope to a Circuit

how to connect an oscilloscope

Oscilloscopes may seem like daunting devices at first, but try not to let the several knobs and buttons intimidate you.

They are extremely useful in the field of electrical studies and tasks concerning electronics.
When connected to a circuit, a USB oscilloscope graphs out the electrical current running through the circuit onto a screen, and they also provide users with the core information needed to work out a lot of other elements such as amplitude, transient signals, statistics, etc.

This article will be walking you through the process of how to connect an oscilloscope to a circuit so that you can get the information you need.

Circuits and Oscilloscopes

A circuit is essentially a gapless path along which a circulating electric current flows. This path is made up of electrical components such as resistors, capacitors, wires, inductors, loads (such as a bulb), sources (such as batteries), etc.

When a circuit is connected to an oscilloscope, the behavior of the current flowing through the circuit is visualized on the oscilloscope’s screen, which can then be observed, analyzed, and used in the form of information for further calculations and measurements.

The oscilloscope presents the voltage of the circuit as a waveform graph, with time (in seconds, milliseconds, microseconds, or nanoseconds) displayed on the horizontal axis and voltage displayed on the vertical axis of the graph.

Calibrating Your Oscilloscope before Connecting It to the Circuit

Before you connect your oscilloscope to your circuit, you will need to prepare the former so that it works properly with your specific circuit’s signal. This is called ‘calibrating’ the oscilloscope.

Depending on the oscilloscope, you can measure as low as a few millivolts to as high as a few hundred volts of voltage, and similarly, you can visualize pulses of both very short durations and of very long durations.


In order to properly see how your circuit’s voltages are changing, you need to scale the voltage and time axes accordingly.

The display of the oscilloscope looks like a simple graph with variable scales for the horizontal and vertical axes.


You need to estimate how high and low your peaks and troughs will go and make sure you set the volts/division and time/division knobs appropriately. Ensure that both the maximum and minimum voltages would be visible on the screen at the same time.


Adjust the horizontal scale so that it fits a few periods (that is, the time required by a wave to complete one cycle).

After connecting the circuit, adjust the scale as necessary. The oscilloscope helps to visually test the circuit, so scale it accordingly so that you can see exactly what configuration you need.

Connecting an Oscilloscope to a Circuit

There is very little that goes into the task of connecting a circuit and an oscilloscope. However, this task may seem difficult in the beginning. The following steps should help you walk through the process easily.

First, connect the probe’s ground clip to the circuit’s ground plane. Next, connect the probe tip to the circuit’s signal output port.

Once these two steps are completed, you should be able to see a line appear on the oscilloscope’s screen. This line is known as the waveform of your signal (that is, of the circuit).

This waveform can help you find out not just the voltage of your circuit, but also the frequency, amplifier gain, current, mean, standard deviation, etc.


Learning to operate any new device is a matter of trial and error. However, when working with electronics, it is essential that you keep yourself safe and also conduct necessary and extensive research before performing a new task using your device.

Hence, follow the steps mentioned above when connecting your oscilloscope to a circuit in order to do it properly and safely.

And if you come across any problems while doing the process, give us a shout in the comments or mail us. We’ll try to provide an appropriate solution to your problem in a short time.
