How To Use Digital Oscilloscope?



The oscilloscope, which is used for many different purposes in many different sectors, was developed over time and turned into a digital device. So what is an oscilloscope? What are the types of oscilloscopes? What is a digital oscilloscope? What are the advantages of the digital oscilloscope? Let's examine together.


What is oscilloscope?

Measuring instruments that can detect the time and amplitude of electrical values ​​such as voltage, current and frequency at the same time and reflect them on the screen in graphical form (waves) are called oscilloscopes. It is often preferred in control and repair processes as it provides information about time interval, rise time and distortion of the signal formed.

The reflection of the oscilloscope on the screen in the form of a wave, in other words, helps to find out exactly where the problems experienced in the devices are caused. For this reason, oscilloscope is preferred more frequently than classical voltmeters. Oscilloscopes are an essential tool for the electronics lab or test electronics equipment.




What are the types of oscilloscope? 

The oscilloscope put forward by Edwin Howard Armstrong was in a very different form than the oscilloscopes used today. The first invented models took their current form with today's technology. The varieties that appear with the development of the oscilloscope are as follows.

  • Analog Oscilloscope:

The working principle of analog oscilloscopes is the same as tube televisions. The electron beam formed in the cathode ray tube has a principle that the input signal applied to the vertical and horizontal deflector coils creates an image by hitting the phosphor screen. The analog oscilloscope is now replaced by the digital oscilloscope.

  • Digital Oscilloscope:

Digital oscilloscopes, which appear with the development of technology, are preferred more frequently than analog models. Thanks to the advanced microprocessors in the digital oscilloscope, it has the ability to transmit incoming signals much faster and with accurate results. The perceived signals can be stopped at any time, triggered at the desired level or recorded. Due to all these features, one of the most frequently used oscilloscope types is digital oscilloscope.

  • USB Oscilloscope:

USB oscilloscopes which are more affordable than other types of oscilloscopes, do not have a screen on them, so a computer is definitely needed. Computer and appropriate software must be available for signal graphics to be displayed like other models.

  • Handheld (Portable) Oscilloscope:

The portable oscilloscope type is preferred because it is small in size and portable. Handheld oscilloscopes that can be used with battery or by charging are highly accurate devices. They are preferred more frequently than other models in terms of durability and portability especially in field applications such as field applications.




What is digital oscilloscope? 

An electronic device consisting of various software and hardware that captures, processes, displays and stores data representing the relevant signals of a device is called a digital oscilloscope. The digital oscilloscope is usually divided into digital storage oscilloscope and digital sampling oscilloscope. The digital oscilloscope contains many elements. These elements are as follows.

  • Analog vertical input amplifiers
  • Analog digital converter
  • Digital waveform memory
  • Time base with trigger and clock feature
  • Circuits for waveform display and reconstruction
  • LCD or LED screen
  • Power supply

Digital oscilloscopes periodically monitor the analog signal in the first step. They compress these signals that they watch and store to different time points using an internal clock. With the oscilloscope, instantaneous amplitude values ​​are measured and data are stored in a digital memory. Digital oscilloscopes are preferred in cases where measurements are required at some points of the waveforms because they have many advantages over analog oscilloscopes in such complex operations.




What are the advantages of digital oscilloscope?

Digital oscilloscopes, which have gained great momentum with the development of technology, are advantageous compared to other types. Because of these advantages, they are used more frequently. The advantages of digital oscilloscopes throughout the process are as follows. 

  • Digital oscilloscopes allow the data obtained during the process to be viewed later.
  • Digital oscilloscopes enable data to be uploaded to the computer.
  • A printed copy of the data obtained by digital oscilloscopes can be created.
  • Digital oscilloscopes store digital data to store the graphics obtained at the time of processing on the floppy disk.
  • One of the most important features of digital oscilloscopes is the capacity to make instant measurements on digital data
  • While analog oscilloscopes must be triggered before the data can be monitored, digital oscilloscopes can display waveforms after they are triggered.
  • Digital oscilloscopes can automatically measure according to manually determined parameters.
