What is an oscilloscope?

An oscilloscope is a measuring instrument for electronics. It represents a graph of amplitude on the vertical axis and time on the horizontal axis. It is widely used by students, designers, engineers in the field of electronics. Frequently it is complemented by a multimeter, a power source and a function generator or arbitrary. Ultimately, with the explosion of devices with radio frequency technologies such as Wi-Fi or Bluetooth, the workbench is complemented by a spectrum analyzer.

The oscilloscope presents the values ​​of the electrical signals in the form of coordinates in a screen, in which normally the X axis (horizontal) represents times and the Y axis (vertical) represents tensions. The image thus obtained is called an oscillogram. Analog or digital phosphor oscilloscopes usually include another input or control, called "Z axis" that controls the brightness of the beam, allowing highlighting or turning off some segments of the trace depending on its frequency of repetition or speed of transition in time.

                                           Utilization

In an oscilloscope there are basically three types of controls that are used as regulators that adjust the input signal and allow, consequently, to measure on the screen and in this way you can see the shape of the signal measured by the oscilloscope, this called In technical form it can be said that the oscilloscope serves to observe the signal that wants to measure.

The first control regulates the X axis (horizontal) and appreciates fractions of time (seconds, milliseconds, microseconds, etc., depending on the resolution of the device). The second regulates the Y axis (vertical) by controlling the input voltage (in Volts, millivolts, microvolts, etc., depending on the resolution of the device).

The third control is the setting of the trigger (or trigger in English), this control allows to synchronize the signals that are repeated periodically using as a reference a characteristic of the signal, different types of trigger are used, the most common being the trigger for flank of rise or fall of the signal, for which the trigger voltage is defined and if the flank is rising or falling.

These regulations determine the value of the grid scale that divides the screen, making it possible to know how much each square of the screen represents, in order to know the value of the signal to be measured, both in voltage and in frequency or period.[pic 3]

Trigger system and controls

The trigger function of an oscilloscope synchronizes the horizontal sweep at the correct point of the signal, an essential function for a clear characterization of the signal. The trigger controls allow to stabilize the repetitive waveforms and capture waveforms of unique occurrence. The trigger causes the repetitive waveforms to appear motionless on the oscilloscope screen, repeatedly displaying the same section of the input signal. It is not difficult to imagine the confusion that would occur if each sweep started at a different point of the signal

  Description of the configuration process of a oscilloscope

 1. The following steps describe how to automatically create a stable oscilloscope presentation with a square wave of 1 kHz

to. Turn on the oscilloscope of the TDS1000C-EDU series by pressing the power button on the top of the instrument.

b. Press the Default Settings button on the front panel to put the oscilloscope at a known starting point.

c. Connect a TPP0101 or TPP0201 10X passive probe to the channel 1 input. To connect a probe using a BNC connector, press and rotate the probe connector until it slides into the oscilloscope's channel input connector. Next, turn the probe retaining ring clockwise so that the probe connector is fixed.

d. Connect the crocodile-style ground terminal of the probe to the ground connector located next to the oscilloscope screen.

 and. Connect the tip of the probe to the Compensation connector of the probe that is just below the connector of the ground terminal. With this connector a square wave of 1 kHz is achieved that will be used in this practice to show how an oscilloscope works

F. Press the Auto Configure button on the front panel to make the oscilloscope automatically set the vertical, horizontal and trigger settings for a stable 1 kHz square wave display of probe compensation.

Description of the configuration process of a function generator

A Function Generator is an electronic device that produces sinusoidal, square and triangular waves, as well as creating TTL signals. Its applications include testing and calibration of audio, ultrasonic and servo systems.

This function generator, specifically works in a frequency range between 0.2 Hz to 2 MHz. It also has a sweep function which can be controlled both internally and externally with a DC level. The machine cycle, DC offset level, sweep range and the width and width of the sweep can be controlled by the user.

1. Controls, Connectors and Indicators (Front)[pic 6][pic 7]

1.-Power button. Press this button to turn on the function generator. If this button is pressed again, the generator shuts down.

2.-Power on light. If the light is on it means that the generator is on.

3.-Function buttons. The sine, square or triangular wave buttons determine the type of signal provided by the connector in the main output.

4.-Range buttons (Hz). This control variable determines the frequency of the connector signal at the main output.

5.-Frequency Control (Frequency Control). This control variable determines the frequency of the connector signal in the main output taking into account also the range set in the range buttons.
