  • The borescope is mainly used in nondestructive testing procedures for understanding defects or weaknesses.
  • Additional common uses contain scientific applications in law imposition and building inquiry, and in gunsmithing for inquiring the inner bore of a firearm.

Some tips on helpful inspection techniques

Borescopes are crucial equipment for the trade. They enable us to see into regions of the aircraft and engine that are not else apparent. Yet, when utilizing these tools, there are few methods that one can use to assure better-detailed inspections.

There are virtually three different kinds of scopes accessible- rigid scopes, video scopes, and fiberscopes. Let’s take a synopsis at every type.

Rigid Scopes

Rigid scopes like the word indicate rigid scopes are inflexible inspection scopes. They enable entry to remote areas that do not need the elasticity of fiber or video scopes. Their benefit is the transparency of the image. Rigid scopes utilize optical (mirrors and lenses) to cast the picture to the eyepiece, so the finding is apparent than those generated with fiber optics. Their drawback is the rigidity that resists them from working in some areas.


Another kind of borescope is a fiberscope. It utilizes fiber vision strands to project the picture from the top of the probe to the lense. Its benefit is its flexibility. It is prepared to tilt in the areas that might be difficult to get to with a rigid scope. The top of the probe is furthermore apt to be worked at one time in a place, say inside a compressor turbine region, to obtain various areas of view. Fiberscopes are moreover eligible to be generated in small diameters.  These fiberscopes are also made with diameters as small as .37mm.   These mini borescopes can be inserted into very tight passages.


The new element of the borescope family is the video scope. It is related to be fiberscope in appearance and undertaking, but that is where the resemblances stop. A videoscope utilizes a charged coupled device to catch the picture at the far end of the scope. It transfers the image electronically via the camera control unit. Videoscopes possess revolutionized borescope inquiries.  Some people may refer to these as a fiber videoscope, video borescope or borescope camera.  All of which infer that there is a micro digital camera involved with the imaging of the inspection device.

Another advancement is borescopes are the UV Borescope.  With the use of a dye penetrant these ultra violet borescopes can help the borescope inspector to identify cracks and other surface flaws.

6 Mistakes to Avoid When Using Sewer Camera for Pipe Inspection

Sewer line cameras help diagnose sewer line problems. These cameras ensure that commercial and residential sewer lines remain in flawless condition.

Following proper procedures is necessary when using pipe inspection cameras. Here are some mistakes that you should avoid when using a pipe inspection camera for sewer line inspection.

1. Never Push the Camera with Force

Most issues with the camera occur when it is pushed inside the pipe with force. Forcing the probe inside the pipe can damage the cable and lens. Maintenance crew must insert the tube carefully inside the pipe.

2. Don’t Use Short, Fast Motions

Another common mistake when using a sewer inspection camera is to use fast motions to get the probe around bends and corners. This could damage the lens of the camera.

To avoid damage, the camera must be moved around slowly inside a pipe. If you move the probe inside the pipe with fast motion in a bid to finish the inspection process quickly, you could end up with a faulty camera that would cost hundreds of dollars in repairs.

3. Always Stand Next to The Drain Opening

The person operating the camera must kneel beside the drain opening when using the camera. The camera can break if the maintenance crew pushes it inside the opening while standing.

A technician must make sure that their hand is near the opening when pushing the camera inside the drain hole. The reeling can kink up and damage the camera if standing when inserting the tube inside the tube.

4. Never Continuously Immerse the Camera in Liquid

Many times a camera becomes defective when the plumbing repair crew immerses it in any liquid thinking that the tube is waterproof. Although the tube is indeed waterproof, the camera is not designed to be continuously soaking in liquids .   The camera should be stored in a dry place and out of direct sunlight as continuous exposure to the sun can dry and crack the camera lenses and supporting adhesive materials.   

5. Don’t Subject the Camera to High Heat

Do not expose the camera to high heat above 800C or 1760F. Exposing the camera to high heat can damage it. You should follow the instruction manual about the high and low-temperature threshold for operating the camera.

6. Never Bend the Tube

The tube or coil of the pipe camera should not be winded. Winding the tube will damage the fiber optics, thereby reducing the quality of the image. It will also damage the articulation cables that will require costly repairs.

You should keep the camera in the proper storage case when not in use. Ensure that the insertion tube is safely inside when closing the lid.

Make sure that you buy a sewer camera from a reliable store online. USA Borescopes is a name of trust that is associated with the sale and repair of pipe inspection cameras for years. Contact us today to know more about our commercial quality pipe inspection cameras.

The Importance of Borescope Inspections

Due to the advents in optical technology and modern electronics, we’ve seen advancements in the borescope industry. Modern devices have made inspections easier and enabled businesses and organizations to keep a tab on their machine components’ performance more effectively. In this article, we’ll discuss the importance of borescope inspections and how it can ensure operational safety as well as save valuable time and money. Let’s get right into it!

What Is a Borescope?

A borescope is an optical instrument with a camera mounted on a flexible tube. It has an eyepiece on one end and the camera or lens on the other side. Borescopes are used to examine narrow, hard-to-reach areas not visible to determine machinery and equipment’s structural integrity. It allows timely identification of hidden issues in tubular areas so they can be addressed before exacerbating into more significant problems. Borescopes have an extensive commercial and industrial application as they’re used extensively in numerous industries, including automotive, aviation, manufacturing, power generation, and more. Borescopes come in different variants, ranging from non-articulating video scopes to rigid borescopes. Each type of borescope is suitable for specific inspection. Many industry-related borescope devices aeroplane and engine borescopes are also available in the market.

Why Are Borescope Inspections Important?

Borescope inspections can play a pivotal part in keeping expensive machinery safe and maximize its useful life. It can help ensure equipment and machinery don’t have potential issues in hidden areas that can lead to operational failure and result in expensive, unnecessary repair and maintenance. It’s a reliable and proven method of ensuring that machine components are safe to use and ensure uninterrupted operations.

Borescope cameras are primarily used for inspection of the mechanical parts as well as plumbing and ventilation. These devices are also useful to examine gearboxes, internal combustion engines, heat exchange tubes, etc. The importance of regular checks varies from one industry to another. For instance, borescope inspections extremely crucial in the aviation industry as they facilitate thorough inspection of aircraft equipment to ensure efficiency and reliability.

What’s more?

Borescopes serve an essential role in ensuring the integrity of the mechanical components in different conditions like extreme cold or heat. Once the inspection is performed, a report can be made with a detailed analysis of the checked equipment condition, which can be studied and used to predict expected useful life and as a reference for record-keeping and future maintenance.

What Is An Industrial Borescope?

Industrial borescopes are used to perform remote visual inspections (RVI) when a naked human eye is insufficient for checking out an inaccessible area.   

Borescopes are used in a wide range of applications, including power generation, automotive, sanitation, aerospace, aviation, metal casting, weaponry, and automotive production. Different industries rely on different designs and features for their remote visual inspection equipment. Over the years, the demand for industrial borescope has peaked due to intense competition around the globe.  So, what is an industrial borescope? Let’s find out.

What Is An Industrial Borescope?

An industrial borescope refers to an optical device that consists of a tube (flexible or rigid) with a lens on one end and eyepiece on the other end, where an optical system connects it.

The camera in an industrial borescope creates high-quality images without breaking the bank. The device also comes with lighting and visual systems. The lighting system entails an optical fiber that is used to illuminate the inside of the area. The visual system is often a rod, gradient, or lens optics that is fitted into an inner metal tube. The optical system transmits the image, which is then seen by the viewer’s eye.

Besides, a video camera is equipped with a borescope, so it can transmit images to a computer or display. There are four parameters that influence a borescope:

  • The length of the operating part
  • The diameter of the operating part
  • The angle of view
  • The angle of the observation direction

Keep in mind that once you expand the field of view, it can reduce the details in the image – you can either barely make out the picture in big sizes or see a lot in small sizes. The lenses will offer at least a 1.5 times magnification and when moved closer to the inspection area the image will appear larger. What makes the industrial borescope stand out from an ordinary borescope is its camera resolution of up to 25 lines per millimeter. 

A borescope is created to handle the work in scenarios when it is not feasible or possible to reach the inspection area. This is why an industrial borescope is widely used for visual inspection in combustion engines, steam turbines, industrial gas turbines, and aircraft engines. The performance evaluation and maintenance of cars and trucks also necessitate the use of an industrial borescope.

When the path between the area and the operator isn’t straight, a flexible borescope is needed. Generally, such a borescope is made of eyepiece lens, protective sheath, objective lens, fiber bundles, focus and diopter ring, a light source, and articulation controls.

The number of glass fibers in a flexible borescope can be as high as 40,000. There are two bundles of fibers in a flexible borescope: the first one is connected to the light source to illuminate the object under inspection, while the second one allows the image to be shown to the eyepiece. These bundles are protected by flexible stainless steel.

Borescopes containing a video processor, display, and probe can fall into either the flexible or rigid category. The probe’s tip consists of an electronic sensor through which the image is electronically transferred to the processor. Apart from creating video images, borescopes are good at producing still images too.

What Can You Do With an Industrial Borescope?

An industrial borescope can help with a wide range of applications. Some of them include the following:

Make Field Inspections

Borescopes are lightweight and small, making them ideal to take with you to the field and perform relevant examinations.

A portable borescope like this one lets you inspect, record, and analyze video of specific locations. Next, you can easily identify faults in no time while you can also use the cloud to save or share recordings with your team members, coming up with a suitable solution for a given problem. Don’t worry about the power source; internal batteries power these units.

Clean Your HVAC Systems

Were you careful with your HVAC maintenance? When your HVAC components like ventilation pipes and boiler suffer from an issue due to poor maintenance, an industrial borescope can assist with checking out the installations. This way, you can detect blockages, leaks, and other issues that can derail performance.

Preventative maintenance is useful as it removes clogs, allowing air to circulate better. As a result, your air conditioner is not forced to spend additional energy for overcompensating.

Besides, an industrial borescope empowers you to lubricate mechanical parts or replace gaskets so that you can extend the service life of your cooling and heating systems, saving considerable money in the long run.

Inspect Your Engine

A high-quality automotive borescope allows you to review the condition of the engine and other systems. Whether you are looking to perform routine inspections or want to locate the area that is causing a problem, an industrial borescope is your friend that can provide help with accessing areas that are hard to reach.

You can probe pistons and valves In order to look for leaks and damage. Look carefully to assess whether you are required to replace old gaskets. Tread carefully while inspecting seals and casting and avoid removing or disassembling the whole engine. Else, you may find later that all your hard work amounted to a futile effort.

An industrial borescope can be your ally that saves a significant amount of resources, time and money in particular. This way, you can identify issues on time and benefit from an opportunity to repair them before they can pose a serious threat and cause major failures. By doing this, you can replace expensive parts before any major damage occurs.

Support for Industrial Borescope

This is an essential consideration as, like any other industrial equipment, the borescope is vulnerable too. To obtain certified borescope repair support for your borescope and order the right spare parts, call us today. Discuss your concerns with our technicians and, if needed, buy a new borescope. We offer a wide range of borescopes for all kinds of businesses.

Borescopes for Williams Turbine Engines

Williams International is an American manufacturer of small gas turbine engines based in Pontiac, Michigan, United States.  They produce jet engines for cruise missiles and small jet aircraft engines.   Williams International is the world leader in the development, manufacture and support of small gas turbine engines. The privately owned company operates R&D (research and development) and R&O (repair and overhaul).

The Williams FJ44 is a family of small, two-spool, turbofan engines produced by Williams International/Rolls-Royce for the light business jet market.  The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word “turbofan” is a portmanteau of “turbine” and “fan”: the turbo portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the fan, a ducted fan that uses the mechanical energy from the gas turbine to accelerate air rearwards. Thus, whereas all the air taken in by a turbojet passes through the turbine (through the combustion chamber), in a turbofan some of that air bypasses the turbine. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust.  Modern turbofans have either a large single-stage fan or a smaller fan with several stages. An early configuration combined a low-pressure turbine and fan in a single rear-mounted unit.

Small turbine engines such as WR19 are finding industrial, marine, automotive, and pipeline applications. Earlier Williams turbojets powered unmanned target drones and were used as auxiliary power units for military transport aircraft. The initial high cost of such powers is often offset by their efficiency, low operating costs, and low maintenance requirements.

Here is a list of Williams Engine Products:

  • Williams WR19 engine, used in cruise missiles and drones
  • Williams F107 engine, used in a variety of cruise missiles
  • Williams F112 engine, used in cruise missiles and experimental aircraft
  • Williams FJ22 engine, a derivative of the FJX-2; also known as the EJ-22, for the VLJ market
  • Williams FJ33 engine, for the VLJ market
  • Williams FJ44 jet engine, produced for light business jet aircraft (a variant of which was used in the Virgin Atlantic GlobalFlyer)
  • Williams V-Jet II aviation engine, light jet aircraft
  • Williams X-Jet engine, experimental VTOL platform from the 1960s
  • Williams WR34 engine, turboshaft
  • Williams WR44 engine, used in cruise missiles and the Foxjet ST600
  • Williams WST117 engine, turboshaft

Of course, like all turbine engines inspections have to be completed on a scheduled basis.   Hot section inspection can usually be performed on wing. The borescope required for this inspection is primarily in the 4mm borescope range.   This allows for the small diameter to enter the targeted area with ease.  Most of the more advanced borescopes will provide 4-way or joystick articulation.

Best Sewer Cameras in the Plumbing Industry

Pipe inspection cameras are essential to any pipeline or sewer inspection. Those in the plumbing industry know technicians must locate the source of trouble in pipes before beginning repairs. This step not only saves you time and effort, it builds trust with your customers. 

According to Plumber Magazine, “Just as patients expect to see the X-ray before the operation, plumbing customers increasingly want to see “proof” of the problem before the repair.” Pipe inspection cameras allow you to locate and diagnose plumbing problems quickly, ensuring your customers get the optimal repair. Faster and shorter projects also means you will get to serve even more customers.

Obviously, these pieces of equipment are a must-have for any plumber. That’s why we’ve rounded up our top three pipe inspection cameras in the plumbing industry below.

What Are Pipe Inspection Cameras?

Before we share our favorite borescopes in the plumbing industry, it’s important we cover the basics on pipe inspection cameras.

A pipe inspection camera, also called a sewer inspection camera or plumbers camera, is a type of borescope typically used in the plumbing industry to inspect sewer systems and pipelines. These devices feature a high-resolution camera mounted to an insertion tube or a flexible rod, allowing the operator to insert the inspection system into hard-to-reach spaces.

The mobility and image-capture abilities of a pipe inspection camera enable a thorough inspection, even when examining isolated areas. This could include pipes behind walls, pipes encased in concrete or plumbing systems beneath home foundations. Plumbing jobs may also call for sewer inspections, meaning you may need to examine underground sewer lines. Employing a pipe inspection camera means you can pinpoint the problem area without excavating plumbing and sewer systems, avoiding costly and labor-intensive inspections.

Though pipe inspection cameras are favored by the plumbing industry for their ability to detect cracks, find blockages and spot leaks, they can also be used by other maintenance professionals. Aviation technicians can use these cameras to conduct aircraft inspections, which include an examination of the engine, airframe, gear boxes, turbines and more. Those in manufacturing, such as oil and gas, may use pipe inspection cameras to inspection natural gas lines and fuel tanks. But for the purposes of this article, we will focus on uses in the plumbing industry.

What Are the Different Types of Pipe Inspection Cameras?

Though all sewer inspection cameras perform similar functions in the plumbing industry, there are several types you can choose from. Some cameras are more flexible and are intended to navigate twisting pipes. Other plumbing jobs require stiff pipe inspection cameras. Let’s explore the different inspection systems and how they are best used below. 

Rigid Pipe Inspection Camera

Rigid borescopes consist of an eyepiece which is mounted to a non-flexible insertion tube or rod. These devices are valued in the plumbing industry because they enable operators to inspect pipes that run overhead. Unlike more flexible inspection cameras, rigid borescopes aren’t influenced by gravity and will hold their shape no matter where they are inserted.

Rigid borescopes make use of glass rod lenses and light fiber bundles to produce high image quality. However, they lack cameras. Those who wish to record pipe inspections can attach a camera to the eyepiece. Additional light sources can also be attached to inspection devices.   Although seldom used in plumbing inspections it is another tool to keep in your tool box.   Don’t confuse rigid borescopes with Rigid Sewer Camera as this a brand name for sewer cameras.

Flexible Push Camera System

Flexible push cameras are used in pipe and sewer inspections that are tight and hard to navigate. This inspection system consists of a small camera which is attached to a snake-like cable, which can handle twisting pipelines. Many flexible push cameras are also articulating, meaning the operator can point the camera in any direction. Using this feature, as well as the flexible cables, the operator can navigate any pipe until they discover the source of the problem.

What is the Right Pipe Inspection Camera For Me?

You may be wondering what makes a good pipe inspection camera. According to Digital Camera World, “there is a lot of flexibility, and the choices have become increasingly bewildering as more players have entered this fast-growing market.” Before we get into our top three picks, let’s go over how to choose a pipe inspection camera.

First, consider the task at hand. What tools will you need to help you complete this job? Insertion probe length, for example, is an important feature to consider. Are you inspecting a home plumbing system or a sewer line deep underground? The length of the probe could be the difference between detecting and repairing an issue, and missing it entirely.

Similarly, you must take into account the diameter of the insertion probe and the size of the pipe inspection camera. Some jobs will require you to examine small pipes; make sure you are properly equipped. At USA Borescopes, we offer pipe inspection cameras as small as 1 inch in diameter. 

Some other features to consider include lighting. When recording a pipe or sewer inspection, sufficient lighting is crucial to capturing high quality images. Consider purchasing a device with adjustable LED lights or adding light sources to your current inspection system.

Your display monitor will also impact the quality of your images. According to the Chicago Tribune, “wireless inspection cameras have been introduced, using WiFi to connect to your smartphone or tablet screen.” With a wireless device, you have the power to choose your display monitor. If you’re working on a more complex project, opt for a larger screen that offers higher resolution.

What are the Top Three Borescopes in the Plumbing Industry?

Now that you know what goes into choosing a pipe inspection camera, here are our picks for the best borescopes in the plumbing industry.

1. PIVS3188DN Manual Push Inspection Videoscope

The portable and lightweight PIVS3188DN videoscope can be used for any pipe or sewer inspection.

The camera head has been manufactured with a spring coiled joint for flexibility and the monitor is equipped with remote control features that control the camera. This allows the operator to easily record video during an inspection.   Many may call this a cheap sewer camera, but more could not be true.  This systems provides everything that that a start up plumbing business would need or those with high risk inspections that don’t want to risk damage to higher cost pipe inspection camera systems.

Additionally, this pipe inspection camera is compatible with eight different LED lights and comes in a waterproof case.

2. Wohler VIS 350

The Wohler VIS 350 is a sewer inspection push camera which can be used for a variety of applications in the plumbing industry, including pipe, sewer and drain inspections.

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!

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.

Hopefully, we were able to provide you everything you were expecting to get in an angled vs straight spotting scope article. To conclude, we would want to wish you good luck and hope that you can quickly acquire your target and easily track it with the scope that you get.

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:

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

What does a digital oscilloscope measure?

A digital scope can measure a lot more than just waveforms. You can display the waveforms, analyze, and store them. They read frequencies, and they take simultaneous readings of different machines.

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.
