Oscilloscope Measure

Briefly, the oscilloscope can be described by simplifying it as follows; The measuring device that allows to see the changes in electrical voltage depending on time is called an oscilloscope.
It is commonly known that a voltmeter is used to make such a measurement under normal conditions. But there are some distinctive features between these two devices. The voltmeter can only show the user the magnitude and direction of the voltage in the circuit numerically. Oscilloscope is a device that facilitates understanding by presenting the change of voltage
depending on time with a user-friendly approach in a two-axis graph more clearly.

How Does Oscilloscope Work?

We can define the function of the oscilloscope as being able to show electrical signals on a kind of screen. We can describe the working principle of the oscilloscope in its simplest form as follows: After electron beams occur in a cathode ray tube, they begin to hit the screen coated with special chemical (phosphorus) and the phosphors are illuminated with each beat, providing an image on the screen. These electron beams spread to the screen of the oscilloscope in a very short time and turn the electrical values ​​we measure into graphics that we can see. An important point to be considered during this study is that the measured electrical signals show the time on the X axis (horizontal axis) and the amplitude on the Y axis (vertical axis). In this way, an electronic waveform can be seen as predicted on an oscilloscope.

How To Connect The Oscilloscope To The Circuit

Since the oscilloscope is a voltage measuring device in the circuit, it is connected in parallel to the circuit like a voltmeter. Different types of oscilloscope probes are available to make this connection. Oscilloscope probes will be connected to the device with screw connectors called

BNC to help the oscilloscope to function.

Types of Oscilloscope

There are most commonly used 4 types of oscilloscope. These are:

•  Digital Oscilloscope
•  Analog Oscilloscope
•  USB Oscilloscope
•  Handheld (portable) Oscilloscope

Let's get to know these 4 types, respectively.

Digital Oscilloscope

It can be shown as the most common type of oscilloscope. They operate thanks to a fast and high resolution analog to digital converter (ADC) circuit and button, and a microcontroller that can control display functions. Due to the support created by these microcontrollers, signals from the input are fast and have high resolution. In this way, the signal monitored in digital oscilloscopes can be stopped at any time, triggered at the desired level and recorded. These kinds of conveniences are the most important factors in choosing digital oscilloscopes.

Analog Oscilloscope

Devices of this type make up the oldest known class of oscilloscope. The working logic is the same as the working logic of a scuba television. Analog oscilloscopes work on the principle that the electron beam in a cathode ray tube deflects on the screen by the input signal applied to the vertical and horizontal deflector coils.

USB Oscilloscope

This oscilloscope type has the same working principle as digital oscilloscopes. The difference is that these devices do not have a screen like digital oscilloscopes. A computer and appropriate software are required to view the signal received with these devices. USB type oscilloscopes offer a much more affordable price option than other types.

Portable Oscilloscope

These devices offer the advantage of being easy to carry as they are smaller and lighter than other types. The disadvantage is that it has limited features. The results of portable portable oscilloscopes that include both battery and charged models; contains high accuracy. This device, which is mostly used in the field, should be extra durable as it is used for malfunction and discovery purposes. So they have much more protective enclosure systems.

Which Values ​​Can Be Measured With Oscilloscope?

Oscilloscopes, which we examine as items above, have the opportunity to measure many values. Thanks to these oscilloscopes, we can see the values ​​that can be measured in the following way:

• Phase difference
• Frequency
• Characteristics of semiconductor elements such as diodes, transistors
• Charge and discharge curves of the capacitor
• Voltage values
• Waveforms of changing electrical magnitudes
• The current passing through the circuit

The sales prices of oscilloscopes vary according to their intended use.
