In this review, we these oscilloscopes on the basis of different categories, users requirements, quality and prices.

The main criteria we considered

If you want to buy an oscilloscope, 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 a workplace or do you need it on the road? Some important factors should be considered like: the bandwidth, the sampling rate, the number of available channels, the measurement accuracy as well as the storage depth. But what exactly does this information mean? We will tell you what you should pay attention to:

1. Bandwidth

One of the most basic sizes you should look for. The bandwidth determines the maximum frequency of all components of an analog signal that can be 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 an oscilloscope 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 so you can represent and compare up to four measurements at the same time.

3. Input impedance

This value corresponds to the resistance. An oscilloscope 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 resolution of an image: 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. It, therefore, indicates the number of points which 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

An 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 an easy, controllable navigation and a 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.

8. Probes

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 parallel bus (can scan several channels)
    • We advise you in general 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.

9. Triggering

Triggering means that you can start the signal acquisition at predefined times (e.g., for individual events). Of course, you need to know what you’re looking for and what events your oscilloscope 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 virtual oscilloscope also offer software packages that are specialized in specific applications, which 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 a good user guidance and intuitive operation quickly. Since such qualities are not apparent from the technical description of the manufacturer, you can check out our detailed tests and product presentations here. Importantly 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 duties and evaluations individually in a personalized interface
  • Interactive online help

12. Connectivity

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
    • GPIB
    • 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. Certainly, 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 if only in English. Especially in the case of technical and complex topics, laypeople should inform themselves in advance or read our tests.

It is also good for you if the manufacturer has a set of probes for each channel, which also corresponds to the analog bandwidth of the device. So you can get started right away.

In the case of battery-operated devices, you should ensure that the delivery is accompanied by an accuracy or replacement pack or if you have the appropriate batteries in stock. Useful is always an external charger.

14. Display

For the display, the requirements are based on what you prefer. Digital storage oscilloscopes are now 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, you will certainly be happy with modern oscilloscopes. A screen, which can represent various signals in different colors (usually ~ 65 k), is in principle also advantageous. 

Necessary Accessories

As already said, it is used to represent an electrical voltage over time. The following paragraph explains which components are necessary. It is technically based on a Braun tube (also called 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 temporal depiction of the voltage profile. 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 velocity of 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 influences the deflection of the electrons in the electric field. So you can control the bundling of the electrons in it. More strong 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 important 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 to 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

An oscilloscope 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 the digital devices over time. It is one of the most important measuring tools in electrical engineering. With such types of devices, you can measure high-frequency electric. Signals in radio, in televisions or even in computers.

1. What is an oscilloscope used for?

Not only the magnitude of a DC or AC voltage can be measured and determined with it, but also 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

2. 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 create an image instead of a bright spot.
  • Another component is the light-emitting layer and the light-emitting point. 

3. How does an oscilloscope work?

In the following list, we explain the most common user functions for an oscilloscope using the above graphic. Certainly, the controls and knobs can vary slightly or be arranged differently on your particular device – but this overview should explain a large part 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.

4. What are the functions of an oscilloscope?

The functions of an oscilloscope are divided into three areas. The users should be careful while using this product.

5. What is triggering an oscilloscope?

To obtain a standing image when measuring with an oscilloscope, the signal to be measured must be properly triggered. Here you can select the channel on how the triggering should take place using a switch. The digital storage oscilloscope has an external trigging input. After running the display, the time-delay generator waits until the measuring signal has the same direction and the same level. Only then it can be triggered again.

6. How to choose an oscilloscope?

I already discussed the considerations areas to choose the best but for technical issues, you should also focus reasons you know the technical issues to be considered.


  1. David Martindale

    The Siglent SDG-1025 (item #6) is a signal generator, not an oscilloscope! It does not belong in this review at all.

  2. GW Instek Announces New 50Ω Impedance Adapter (GAK-003) Option for the GDS-2000A Series Digital Storage Oscilloscopes… Do you think GDS-1000B is better than GDS-2000A?

    • Thanks, cooper. This it should be offered as a standard option with every new Oscilloscope. similar third-party solutions retail at 40 – 50 USD. The GDS-1000B is better in some cases like its providing 100 MHz, 70 MHz, 50MHz compared to GDS-2000A it’s providing 70 MHz. But the price of GDS-2000A is quite similar.
      On the other hand, GDS-2000A is providing some facilities like- 80,000 wfm/s Waveform Update Rate and VPO Technique, Function Generator Option, Upgrade to Mixed Signal Oscilloscope (MSO), Design for Plugged-in Options, Segmented Memory, Zoom Window, Mixed Signal Oscilloscope(MSO), Complete Trigger Functions, 36 Automatic Measurement, Data Log, CAN/LIN Bus trigger and analysis, Advanced Logic,Various Interfaces Support, Option of DDS Signal Generators.

  3. Thanks Alex.

  4. Alex you are really great and thanks again for your help and after your review I bought it and its really working like a pro 🙂

  5. What probes would I be able to use with this degree that will enable me to take a gander at 50 microvolt motions between 500 Hz and 30 MHz in Siglent Technologies SDS1052DL?

    • If you have a known pickup intensifier that will work at 50 UV and in any event appear on your most reduced vert. Input setting it should work OK for you. I’ve utilized this procedure. You would utilize an x-1 test. An unpleasant estimation on an adjusted beneficiary would be an S-9 perusing on its S-meter.
