Borescopes Inspection Camera provides you the decent picture quality and measurement ability on your optical inspection device so that you could be optimistic; your inquiry is detailed and accurate.
Borescopes are generally utilized in the visual inspection of aircraft engines, aero-derivative industrial gas turbines, diesel engines, steam turbines, pharmaceuticals, food and beverage, and truck engines.
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 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.
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.

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.
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.

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.

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?
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
CRT and LCD
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
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:
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.
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 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.
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.
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:
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.
Most oscilloscopes can display waveforms triggered by either an internal or external signal (from another source).
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.
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 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.

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.
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.
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.
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.
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.
Siglent Vs Rigol (Pros and cons)

Rigol DS1054 warms the heart for its number of channels; However, its bandwidth is lower than its main competitor. 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
An oscilloscope is a device used to view the voltage of an electrical component in the form of waves on a screen. It consists of a screen, input ports, and several controls. Oscilloscopes can be either analog or digital.
Most current oscilloscopes will provide you with the readings for voltage and frequency. They usually have other statistical information such as standard deviation and mean.
That said, if your budget oscilloscope does not have these features, you could manually calculate the frequency by yourself.
So, let’s learn how to calculate the frequency from the oscilloscope.
Oscilloscopes and Frequency
Essentially, an oscilloscope visualizes electronic signals (or voltage) passing through a component (such as a wire). It does so by turning the electronic signals into a graph on its display screen, where the voltage is displayed on the vertical axis, and the time is measured on the horizontal axis of the graph.
Most oscilloscopes can display both AC (alternating current) and DC (direct current) waveforms. The time and voltage units on most oscilloscopes can be adjusted from seconds per division (s/div) to nanoseconds per division (ns/div) and from volts per division (V/div) to microvolts per division (μV/div), respectively.
Measured in hertz, frequency is the number of times oscillating waves pass a certain point on the graph every unit of time (so, for example, five waves per second).
Finding out the frequency of a voltage waveform can be useful for myriad reasons. The most common of them being that, when the frequency of the waveform of a component’s voltage is measured, it can tell us whether the component is working as it should be or if its voltage needs to be fixed.
Calculating Frequency Using an Oscilloscope
Let’s go through the entire process.
Enlarging Display Area
Start by making sure the signal area on your oscilloscope’s display is enlarged.
Then, measure the time value using the horizontal scale of your oscilloscope, and also by counting the number of divisions (horizontally) between the two ends of a wave, along the Center Horizontal Graticule Line.
In simpler words, this means to count the number of divisions between the peak points of the waves on the waveform of your signal (or a part of the signal’s waveform whose frequency you wish to calculate).
The next step is to multiply this number of horizontal divisions by the time/div value to find the signal’s “period”. And the period of a wave is the amount of time it takes for the wave to complete a full cycle.
Now that you have all your elements, you can use a simple formula to find out the frequency of the waves. This formula will have you divide the value 1 by the period of the wave (or waves) in order to calculate the frequency. So, the formula for this would be: frequency = 1/the period of a wave.
As mentioned before, finding out the frequency of a waveform is only a matter of navigating on a screen in the case of most modern oscilloscopes.
However, if needed, this frequency can also be worked out manually using the few steps mentioned above.
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.
