Meaning of Oscilloscope (What is it, Concept and Definition)

What is an oscilloscope:

The oscilloscope is known as the device that allows you to visualize the representation and registration of electrical signals that may vary over time , and the image obtained is known as oscilloscope .

The main function of the oscilloscope is present the values ​​of the electrical signals, in the form of coordinates, through a screen .

Generally the “X axis” symbolizes the times, and the “Y axis "Represents the input voltages in volts, mini volts, micro volts, etc.The set of these images is called an oscillogram.

In addition, the" Z axis "or THRASHER which is responsible for controlling the beam brightness, allowing to enhance or eliminate some segments of the graph.

Uses of the oscilloscope

As such, the oscilloscope is an apparatus or mechanism that can be used in d Different fields of work because it has the ability to measure various phenomena, so much so that even in the area of ​​medicine they can be used.For example:

• The value of a pressure
• Heart rate
• Sound power
• The level of vibrations in a vehicle.
• Measure phases between signals.
• Parts of the oscilloscope

Parts of the oscilloscope

The oscilloscopes are composed of a set of basic parts that make possible measurements and visual representations of the data so that they can be analyzed by specialists.

Cathode ray tubes : also known as a screen, are those that contain fluorescent substances inside them and that allow visualizing the signal to be analyzed.

Time base : its function is to get the applied voltage to appear on the screen as a function of time, on the “X axis”, as mentioned above.

Horizontal amplifier : aims to extend the signals it receives through the horizontal input (X), that is, signals that come from the time base.

Vertical amplifier : is responsible for increasing the signals received by the vertical input (Y).

Synchronization system : allows the image in the cathode ray tubes or screen, look sharp and stable.

Types of oscilloscopes

There are different types of oscilloscopes, the most used are eldigital , the analog and the automotive , the latter is used to measure actuators, sensors, among others.

You can also name the integrated oscilloscopes on PCs , which is a device that connects as an interface, for this you must first install the program on the computer.

Digital and analog oscilloscope

The analog and digital oscilloscopes are the most used.The analog oscilloscopes work directly with the applied signal, which, when amplified, deflects the electron beam in a vertical direction proportional to its value.

Digital oscilloscopes, on the other hand, previously use an analog-digital converter in order to digitally store the received signals, and then reconstruct the information reflected on the screen.

Below are the advantages , differences and the field of use that both oscilloscope have, the following can be mentioned:

Analog oscilloscope Digital oscilloscope The signal is periodic as it is the only way to refresh the trace on the screen.The signal is digitized by a digital analog converter.High frequency signals reduce the brightness, consequently it is not very clear.Clean and bright trace.Limited mem storage oria.Unlimited storage of memory.Does not allow for pre-shooting.Preview shooting (pre-t riggering ) for viewing short-lived events, data that is then transferred to the computer.It has a bandwidth in sampling Actual.Constant bandwidth dependent on amplitude.The costs of these equipment are moderate.The costs of these equipment are high.
