THE VIRTUAL INSTRUMENTATION OSILOSCOPIO

To delve the subject of an oscilloscope is necessary to know some meanings or concepts of which will help us better understand the issue and make it easier to learn this.
Basics:

measurement: the comparison is of two things, it's as if we compare what is already known to something which we know as measured.
measurement instrument: is an object that allows us to make a measurement such as a rule.
Science: is responsible for studying the behavior of the issues that is referring them and the reactions around you to know how to merge and why.
Strength: is the physical ability to perform work.
matter: is anything that can be touched and that is composed of particles.
Particle is a small part of matter.
Electrical Load: is property of the particles to attract or repel. Electron
: are particles that contain an electrical charge.
Physical Phenomenon: is the behavior of an object.
Electrical is a physical phenomenon caused by electric charges. Appliance
: object which needs electricity to function.
Electronics: is the science that is responsible for studying the behaviors whose operation is based on electron movement and action of electrical forces.
Electrical: is an object which works through electricity.
Signal: is a symbol that represents something or warn of something in terms of electronics is to represent the behavior of a sound or an electric element.
Voltage: is the force that governs energy particles to be displaced.
Current: is the amount of energy passing through a place.
Displacement: is the change from place to place.
circuit or electrical circuit: is a set of electrical components.
Plano: place where you can represent a graph.
X axis or Y-axis: are the horizontal side (X axis) and vertical side (y axis) of a plane.
graphic representation or chart: is the way to show the figure of something on a plane.
Data: Information is or rather what is being communicated.
Memory: where data is stored.
Period: is the time it takes a signal to repeat his behavior.
Direct Current CD: are the signals that have only positive voltages. AC
CA: are the signals that are positive voltages and negative voltages.
Frequency: is the number of repetitions that has a signal.

Oscilloscope:

The oscilloscope is a measuring instrument that allows us to graphically represent the signal, figures are shown by a screen, which indicates the time of that signal through the x-axis and through the axis and indicates the voltage.

This screen is made up of a by divisions which are made by the axes above, these divisions can be controlled by knobs as we indicated equivalent each box, either the times or voltages above the axes.

oscilloscopes can change various things from the signal to which you are making measurements, you can work with direct current signals DC or AC power signals, also modify the working time signal.

oscilloscopes help us diagnose any problems with an electrical circuit (radio, tv or just an appliance containing such circuits), thanks to this device we can see different signals (different forms).

Some things we can do with an oscilloscope are:

* measure the period and the signal voltage

* can see part of the signal is CD and AC.

* We used to identify faults in a circuit.

Two types of oscilloscopes classified according to the internal operation performed by the oscilloscope:

Analog Oscilloscopes

The measured voltage will be sent to the vertical plates (vertical baffles) a mechanism to be viewed on the screen (CRT), the input signal introduce an amplifier which helps keep the signal more strongly by increasing some of its features while horizontal plates (horizontal deflection plates) of the mechanic, it will introduce a voltage signal called sawtooth (signal grows and falls repeatedly triangular or a saw pun intended), another terminal device positive and negative connected to another electronic device (which is plugged in moderating the electricity needed), to create a beam (light beam) passing through the plates that show us the signal is entering.

The analog oscilloscope has some limitations with which it works:

The signs must be repeated in a given time for these signals are known as periodic signals.
very fast signals reduce the brightness for display.
slow signals are not pictures to be shown, is so slow that the light beam is not no figure appears, and this does not help us make our measurements.

For this scope is used commonly used cables that are connected to the oscilloscope estradas call tip tips oscilloscope or direct. These cables are connected to the electrical circuit, the black terminal is for the negative polarity of the electrical circuits, also called earth ground (earth ground by definition is the lack of energy at a certain point, which helps energy flow through the circuit according to certain laws of electricity), and the red terminal is to the point where energy starts to the displacement of particles of the same.

Digital Oscilloscopes

digital oscilloscopes contain a converter analog-digital which allows you to pass data to measure signals into digital form through processes which are called modulation (which consists in dividing the signals into small parts to a certain number of moments of time so that they could convert to digital processes which are represented by zeros and ones which, in turn symbolize signal voltages to be stored in internal memory of each oscilloscope and be shown to the user so that it can understand) in order to be measured in a more accurate, also helps us to measure many more things that that the analog could not perform, as different moments in which the beam of the display is triggered, the signal peaks as well functions that have analog oscilloscope.

This oscilloscope provides many measurements that would be done manually, can also use the leads (offset point) which we used to measure signals in electronic circuits, and these cables also allow us remove some unwanted signals that may occur, these unwanted signals are caused by the environment in which we work, because there is electricity in the air (static) affecting our measurements or because where they have no control over .
