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.
Input channelsBuying 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. Input impedanceThis value corresponds to the resistance. It usually has the input impedance 1 M-Ohm or 50 Ohm, to load the measuring point (. 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). 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.
TriggeringTriggering 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 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). Application supportSome manufacturers like HP who manufacture virtually and 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.
Easy operationParticularly 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 technical description of the manufacturer, you can check out our detailed tests and product presentations here.
Importantly it is among other things. Another scope of deliveryAlso, 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 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 suitable 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 accuracy or replacement pack accompany the delivery or if you have the appropriate batteries in stock. Useful is always an external charger. DisplayFor 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 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 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 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.
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 types of devices, you can measure high-frequency electric. Signals in radio, in televisions or even in computers. 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. 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. 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.
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. Thanks, cooper.
