The main criteria we considered
If you want to buy, you always have a question about the planned use. This means for you: what do you need for it? What do you want to measure it? Is it stationary in the workplace, or do you need it on the road? Some important factors should be considered: the bandwidth, the sampling rate, the number of available channels, the measurement accuracy, and the storage depth. But what exactly does this information mean? We will tell you what you should pay attention to:
One of the most basic sizes you should look for. The bandwidth determines the maximum frequency of all components of an analog signal detected by the device at maximum. Remember: The highest bandwidth is not always the best choice – where you have to decide from application to application (as with the selection of suitable probes). This is because too high bandwidths can also increase the noise level and the noise (because you also detect much more disturbing and falsifying signal components from outside) or reduce the accuracy and resolution. In principle, the bandwidth should be at least twice the maximum frequency of the transmitted signal. High bandwidth is particularly necessary for high-frequency signals,
Tip: With DSP, you can select different bandwidths and thus to adapt to your current circuit. This way, you suppress deliberately distracting secondary signals and noise.
2. Input channels
Buying means that the flexibility and accuracy of the channels are critical. There is the choice between analog or digital input (a digital input can only detect the state – a 0 or 1 is output via a predefined threshold value). With first insulated data, you can avoid short-circuits during power supply measurements. Of course, you should also consider beforehand how many signals you want to measure. They have one to four channels of the input signal to represent and compare up to four measurements at the same time.
3. Input impedance
This value corresponds to the resistance. It usually has the input impedance 1 M-Ohm or 50 Ohm, to load the measuring point (<< 1 MΩ) only slightly. By connecting a probe head, this input resistance can be increased to 10 M-Ohm or more. The input resistor should be tuned to your bandwidth and probes.
4. Sampling rate
The sampling rate is another important point when you want to buy this device. It determines the resolution and accuracy of the measurement decisively – because it determines how many details of the lines and waveforms can be recorded and stored by your analyzer. To do this, you must know that the waveform consists of individual sample points. The more points the wave has, the more accurate and finer it can be displayed. This is roughly comparable to the image’s resolution: the more pixels an image has, the more precise and sharper details are revealed. We recommend that the sampling rate is at least five times higher than the input frequency. Example: 1GHz bandwidth requires 5 Gigasamples of the scanning rate!
5. Saving depth
It stores the detected signals until its memory is filled. The storage depth defines exactly this space required for this. Therefore, it indicates the number of points that can be stored when a complete signal is recorded. The higher the memory depth, the larger the size, and the duration of the signal recording.
6. Health navigation & Zoom
Accurate and comfortable navigation allows you to move along the saved graph, to scale your image section horizontally and vertically, and to select the appropriate section to analyze. And especially with great memory depths and very extensive waveforms, a zoom is indispensable for an accurate evaluation. You should pay attention to easy, controllable navigation and powerful zoom.
7. Automatic measurement functions
These are various convenience functions to analyze the graph – such as amplitude measurements, temporal measurements, rise times, period duration, etc. Select the appropriate analysis function and read the result.
Probe heads take the desired values, e.g., Voltage, current or optical signals. The scope of delivery usually has at least one probe, more preferably two. This way, you get the probes directly you need and are appropriate for the device and do not have to look for suitable probes for your measurement intent.
- When purchasing probes, be aware that they affect the measuring signals as little as possible (active probes will change the voltages, for example, less than passive costs, but usually also more)
- Digital probes are to be used with the parallel bus (can scan several channels)
- In general, we advise you to compatible system heads, which are calibrated together with the system, can be directly recognized by it, and allow special functions.
- There are different types of probes: hand-held probes with manual holder, soldering probes (for soldering to the signal source), etc.
Triggering means that you can start the signal acquisition at predefined times (e.g., individual events). Of course, you need to know what you’re looking for and what circumstances it can trigger. The triggering itself takes place in real-time (analog) and causes the detection.
There are hardware and software triggers as well as probe shapes such as “Visual Triggering”: In this variant, you can, for example, place self-defined areas over the graph and define them as a barrier or transition zone. The trigger jumps in this case only if the signal interacts with the fields you specify (it runs through or does not happen – depending on the settings).
10. Application support
Some manufacturers like HP, who manufacture virtually and offer software packages specializing in specific applications, make the process (measurements, analysis, report) quite simple.
For this, of course, you need to know what you want to measure and capture in what context.
11. Easy operation
Particularly with the intensive use of the device, you will appreciate the right user guidance and intuitive operation quickly. Since such qualities are not apparent from the manufacturer’s technical description, you can check out our detailed tests and product presentations here. Importantly it is among other things:
- Inputs graphical menu guidance, convenient functions
- Settings can be saved
- Good cars
- Straightforward and intuitive selection duties in the context menu via right-click
- The dashboard is possible: this allows you to compile tasks and evaluations individually in a personalized interface
- Interactive online help
Surely your product also needs appropriate connection possibilities. Again, the requirements depend on your application. The following things you should consider:
- Slot for memory card
- USB port
- Graphics card connector for connecting to an external monitor
- Printer connection for direct printing
- Programming interface
- Data transfer to MS Excel or Word for evaluation
- LabView for detailed analysis
13. Another scope of delivery
Also, the delivery of a connection cable (usually USB) and corresponding drivers are advantageous so that you can connect the device to your PC, if necessary – with mobile devices – recharge the battery and document the measurements on the PC. For this, of course, a similar PC software is recommended. Indeed, not but with some manufacturers an excellent Drinkable. Apart from this, a printed manual is hardly included in the scope of delivery. Meanwhile, some manufacturers are changing to PDF documents, so the instructions are always up-to-date, even in English. Especially in technical and complex topics, laypeople should inform themselves in advance or read our tests.
It is also suitable for you if the manufacturer has a set of probes for each channel, which also corresponds to the device’s analog bandwidth. So you can get started right away.
In the case of battery-operated devices, you should ensure that the accuracy or replacement pack accompanies the delivery or if you have the appropriate batteries in stock. Useful is always an external charger.
For the display, the requirements are based on what you prefer. Now they are available in the handy pocket format, while analog devices have a correspondingly large display due to the cathode ray tube used. In general, if you are looking for mobile devices and have no problem with smartphones. A screen, which can represent various signals in different colors (usually ~ 65 k), is, in principle, also advantageous.

As already said, it is used to represent an electrical voltage over time. The following paragraph explains which components are required. It is technically based on a Braun tube (also called a Brown tube or cathode ray tube). Some say the name is still a term from physics teaching. In this paragraph, we will clarify the essential components of this product. The Braun tube is an electron beam with a visible electron beam for the voltage profile’s temporal depiction. The structure is as follows:
The Brauner tube directs the electrons, due to electromagnetic fields, so that they fall on different light sources.
- Cathode: A heated cathode (with voltages between -200 to -800 volts) emits the electrons. These migrate by attraction to the opposite anode.
- Anode: The anode is opposite the cathode and controls the electrons (with applied voltages of +100 to +200 volts). Their speed is so high that the electrons directly pass through the anode.
- Electron optics / concentrating coils: The electron optics influence the electrons’ deflection in the electric field. So you can control the bundling of the electrons in it. More robust and focused electrons appear in the light-emitting layer as a clearer and sharper point.
- Wehneltzylinder: Thanks to the Wehneltzylinder, you control the intensity and, thus, the brightness of the bright point on the front screen – the so-called light layer. The strength is influenced by the velocity and density of the electrons.
- Luminous layer/screen: Here, the deflected electron beams meet and are readable and readable by the user for the measurement.
- Baffle plates/deflection coils: It is essential to know that electrons are the lightest electrically charged elementary particles, but they have an (albeit minuscule) mass. This makes it possible to divert them in their orbit with electromagnetic fields or gravitational forces and control them in a targeted manner. It is precisely this physical effect that makes use of it: two opposing deflection plates ultimately produce the original line image. As the name implies, they deflect the electron beam in several directions. The X-plates allow the time measurement with their horizontal deflection (left and right). With their vertical deflection (top and bottom), the Y-plates again visualize the voltage measurement.
Frequently Asked Questions
This device is an electronic measurement device, which reflects voltages and their course visible on a screen. They are differentiated into analog and digital. The analog devices use a cathode ray tube to display digital devices over time. It is one of the most critical measuring tools in electrical engineering. With such devices, you can measure high-frequency electricity—signals on radio, televisions, or even in computers.
1. What do oscilloscopes measure?
Oscilloscopes are instruments used to analyze electrical signals and provide information about properties such as amplitude, frequency, rise time, time interval, and distortion. They are vital pieces of equipment for those who work with electronics.
2. What is a digital oscilloscope?
A digital oscilloscope has a broader range of functions than its analog contemporary. It is not only able to measure waveforms, but it can also be used, among other things, to display them, store them, process and analyze them. The added advantage of these types of scopes is that they can take simultaneous readings of different devices.
3. Why should I use an oscilloscope?
An oscilloscope is an essential tool for anyone who designs, troubleshoots, or otherwise works with high-speed electronics.
The essential purpose of an oscilloscope is to display electronic signals. These images can help determine whether or not a component of an electrical system is behaving correctly.
There are several different oscilloscopes available to suit both hobbyists and professionals alike.
4. What are the main types of oscilloscopes?
- Cathode ray oscilloscope
The cathode ray oscilloscope is the most basic type of o-scope. It is referred to as an analog scope to differentiate it from later models. These models work in a slightly different way.
This particular model uses a cathode ray tube and photoluminescent phosphor, which illuminates every time an electron hits it. The more collisions, the higher the intensity of light at that spot and so a waveform can be detected.
As the illuminated phosphor does not immediately disappear, it is possible to view several traces overlapping one another. This function is particularly useful for detecting glitches or irregularities in the signal.
However, this model of o-scope cannot capture waveforms, so, once the phosphor delaminates, the information is lost.
Yet, these models still have their uses when it comes to troubleshooting. Most digital oscilloscopes merely sample the signal and so can miss some transient signals that can be responsible for erratic behavior. Analog scopes are generally more affordable than their digital counterparts – making them an excellent option for hobbyists and beginners.
- DSO oscilloscope
These days most digital oscilloscopes are of the DSO variety. This is due to the advanced features it provides in comparison to the analog model.
This oscilloscope was designed to overcome the issues of capturing and storing information about waveforms for later analysis. The way it does this is by sampling the analog signal and converting it into a digital record at each sample time of the signal’s amplitude. This information can then be converted back to an analog signal for display on a cathode ray tube or transferred to another device such as a computer for further analysis.
This particular scope’s limitations lie in its lack of ability to analyze very complex waveforms such as those found in TV systems or smartphones.
- Mixed-signal oscilloscope
The mixed-signal oscilloscope was developed to meet the increasing need for an instrument to monitor analog and digital signals simultaneously. This hybrid device has input channels for both types of signals; thus, it eliminates the need for a logic analyzer.
This type of scope’s main benefit is that it allows the user to view multiple time-aligned digital and analog waveforms on a single display while still being relatively simple to use. This function makes it an appropriate tool for debugging embedded designs.
Compared to a logic analyzer, this instrument lacks many digital acquisition channels and advanced digital measurement functions. Its capacity, though, is generally considered to be ‘just enough’ for most types of projects.
- Dual-trace oscilloscope
A dual-trace oscilloscope can be used to produce two traces from a single electron beam. Two methods are used for this: alternate and chopped mode. The alternate mode allows for the connection between both channels alternately. In the chopped mode, the switch occurs freely and at a very high frequency. This allows for ease of comparison between input and output.
Dual trace scopes should never be confused with dual-beam scopes. The latter of which produces two separate electron beams on a single scope.
5. What is bandwidth?
The bandwidth of an oscilloscope is the range of frequencies that it can accurately measure. This is expressed in Hertz or MHz.
The bandwidth is often regarded as the single most important characteristic of an oscilloscope. Too little bandwidth can mean that your signal’s amplitude will be incorrect, and some details of your waveform might be lost. Too much bandwidth can mean that you capture excessive noise, and thus your measurements will be inaccurate.
Entry-level scopes will typically have a bandwidth of 100 MHz. They can accurately (within 2%) show the amplitude of sine-wave signals up to 20 MHz.
6. What oscilloscope bandwidth do I need?
When looking to purchase an oscilloscope, it’s vital to understand the types of signals you are going to be measuring.
Using this information, a way to quickly determine your bandwidth needs is to look at the digital signals’ maximum frequency. A good rule of thumb is to select a scope with a bandwidth five times higher than this.
Consider also that the higher the bandwidth capabilities of the o-scope, the higher the price. So, while you want one that can handle the signals you are measuring, you don’t want to go over the top with this.
7. What is an oscilloscope used for?
The magnitude of a DC or AC voltage can be measured and determined with it and its temporal progression. The voltages required for measuring are connected via so-called BNC sockets on the front side using a probe.
It can measure the following variables:
- The frequency of a Signal or measuring sounds wave
- The electrical current -> this can be determined, for example, using a current clamp Frequency response of electronic circuits
- Graphs of pulses on digital microprocessors and circuits
- The phase shift of a signal with a Lissajous figure
8. Which components are involved in the measurement?
- It consists of a cathode, which is responsible for the delivery of the electrons.
- Also, it contains a Wheel cylinder, which influences the brightness of the screen.
- Also, an electron optic is installed. It is responsible for the deflection of the electrons into an electric field.
- There is also an anode. Their task is to control the speed of the electrons.
- Also, baffle plates are present, which creates an image instead of a bright spot.
- Another component is the light-emitting layer and the light-emitting point.
In the following list, we explain the most common user functions using the above graphic. Indeed, the controls and knobs can vary slightly or be arranged differently on your particular device – but this overview should explain many of the controls.
Note: In the following, the term “div” is often mentioned. The abbreviation Div comes from “Dive,” which means “part.” Divis thus in the case for a raster unit.
10. What are the functions of an oscilloscope?
11. What is triggering an oscilloscope?
To obtain a standing image when measuring, the signal to be measured must be appropriately triggered. Here you can select the channel on how the triggering should take place using a switch. This device has an external trigging input. After running the display, the time-delay generator waits until the measuring signal has the same direction and at the same level. Only then it can be triggered again.
12. How to choose an oscilloscope?
I already discussed the considerations areas to choose the best, but you should also focus on reasons you know the technical issues to be considered for technical issues.
