What Is An Oscilloscope Used For?



Oscilloscope, one of the indispensable elements of electronic circuits, is actually a measuring device. What is the oscilloscope used in most electronic circuits? What is an oscilloscope used for? What values ​​can be measured with the oscilloscope? How does the oscilloscope work? Who use oscilloscope? Let's answer together.

What is an oscilloscope?

The oscilloscope can basically be described as a graphic display device. Devices that classify the electrical signals present in their channels according to their time and amplitude on their screen are called an oscilloscope.

Often a voltmeter is preferred to measure electrical voltage. While the voltmeter shows the magnitude and direction of the voltage present in the circuit numerically, the oscilloscope presents the voltage in the form of a graph. The oscilloscope is an advanced version of multimeters. They are the devices with the most measurement possibilities.

What is an oscilloscope used for? 

Since the oscilloscope separates electrical signals according to time and amplitude conditions and makes them visible, it is frequently used in repairing electronic devices such as cameras or televisions. Companies producing such electronic devices create circuit diagrams of these devices and show the required signal form here.

The technicians who repair the devices check the compatibility by comparing the signals measured by the device with the signals in the circuit diagrams when they need to use an oscilloscope for device control or repair. In this way, they can monitor if there are any problems on the device.


What is oscilloscope used in electronics? 

Many signals are generated to achieve the intended goals in the electronics and IT sectors. These signals travel by changing or not changing the circuits found in the devices. The production of these signals and their quality on the road are evaluated by the oscilloscope.

The quality of these signals, namely their sharpness, their suitability to the desired form, are very important since they are decisive in the characteristics of the circuit such as energy efficiency and operational stability. For example; In the repair of electronic devices such as digital clock, oscilloscope is preferred for operations such as monitoring the signal on the crystal ends, observing the signal on the processor outputs and understanding the signal in the driver's integration.

What is oscilloscope used in medical?

Today, there are many medical medical devices such as magnetic resonance imaging (MR), ultrasonography (USG), x-ray device, angiography device, mammography device, defibrillator or electrocardiography (ECG).

As in the electronics industry, an oscilloscope is used for the control and repair of the devices in the medical. In addition to control and repair, it is also often preferred in circuits produced for wireless transmission of signals to other devices. In this way, the medical results are obtained completely and accurately.


Which values can be measured with oscilloscope?

Since the oscilloscope is used for several different purposes in many sectors, the values ​​it can measure are also quite high. The values ​​that can be measured with the oscilloscope are as follows.

  • AC and DC voltage values ​​measurements
  • Waveform measurements of variable electrical quantities
  • Current measurements passing through the circuit Circuit frequency measurements
  • Phase difference measurements
  • Capacitor charge and discharge values ​​measurements
  • Time measurements
  • Pulse width and rise time measurements
  • Characteristics of semiconductor circuit elements such as transistors or diodes


How the oscilloscope works?

The oscilloscope, discovered by Edwin Howard Armstrong in the late 19th century, is among the technologically fast developing devices. This device, which was originally called electromechanical oscilloscope and recorded electrical measurements on moving paper tape, was developed only 4 years after the discovery and was called an analog oscilloscope.

Thanks to the analog oscilloscope developed by German physicist Karl Ferdinand Braun in 1897 with a phosphor screen with cathode ray tube, electrical signals could be reflected on the screen. Analogue oscilloscope is basically; The switched measurement input, where capacitor filtering of AC and DC electrical signals is made, consists of amplitude signal amplifier, trigger connected to amplitude amplifier, time axis generator and cathode tube. Thanks to the horizontal and vertical routers in the cathode ray tube, it provides a more detailed view of the amplitude and time values ​​of the signal formed on the screen.




Who use oscilloscope?

The oscilloscope can be used in many sectors. It is also preferred in many professions from technicians to physicists. In addition to the embedded systems to be created in the automotive industry, an oscilloscope can be preferred for the sensors of the engine control units. Oscilloscope is preferred in medicine as well as the automotive industry. A medical researcher can use an oscilloscope to measure brain waves. Technicians looking at the repair work can use the oscilloscope to repair an electronic device. Since the possibilities are endless in the use of an oscilloscope, it is a very functional device.
