The Y (vertical) axis measures the magnitude of the sign on the screen, while the x-axis represents time on an Oscilloscope screen.
Each value shown on the oscilloscope provides information about significant factors such as voltage, current strength, and other variables. We must first learn the terms used on the oscilloscope screen in order to understand how to read an oscilloscope screen.
We must concentrate on reading graphs and representing graph values primarily in order to interpret oscilloscope screens. The x-axis and y-axis concepts and their representations will need the majority of our attention.
How to Read an Oscilloscope Screen
Oscilloscopes come in many different varieties, but they all have the same fundamental parts. Electrical voltage in the current may be measured using the oscilloscope’s timeline. Time is displayed on the horizontal X-axis, while voltage data is displayed on the vertical Y-axis. It is visible on the screen.
You see waves on the screen when you activate an oscilloscope or when you try to test something that an oscilloscope can measure, such as the form of a signal, measure frequency or amplitude, or observe a noise from a signal.
Common Waveforms Displayed on the Oscilloscope Screen and Their Source
- Sine Wave-Electronic Outlets can be the source of it.
- Damped Sine Wave
- Square Wave
- Rectangular Wave
- Sawtooth Wave
- Triangle Wave-Automobile can be the source of it.
- Step Wav
- Pulse Wave- A computer can be the source of it.
- Complex Wave- Television can be the source of it.
Voltage Measurement
Voltage, which is measured in volts, is the difference in electrical potential between any two points in a circuit. The oscilloscope can measure high frequency, direct current, and alternating current signals up to a maximum of 400 Volts.
The Y (vertical) axis is used to measure the amplitude of the symbol on the screen. On the screen, squares are used to determine the amplitude initially. The voltage’s real value is then calculated by multiplying the sign on the Volt / Div input attenuator commutator by the number of frames.
The continuous amplitude adjustment knob, if present, must now be turned all the way to the end in the clockwise or counterclockwise direction. If the amplitude is reduced by the probe,
Period or Frequency Measurement
There is a frequency measurement cap on each digital oscilloscope. When monitoring high frequencies, it is important to pay attention to this limit. An oscilloscope connection is made to the point being measured after choosing the digital oscilloscope appropriate for the frequency value to be monitored.
However, oscilloscopes are now used to measure period rather than frequency. On the X (horizontal) axis, period measurements are done. By counting the squares, one may tell how long one period of the waveform is in the X-axis direction.
By multiplying the number of frames, we can get the value of the time/div button. The attenuation coefficient is doubled and taken into consideration, though, if the probe deteriorates.
How Do You Read an Oscilloscope Clock
You can measure time in a manner similar to how you measure amplitude. Just count the number of horizontal divisions and multiply that number by the horizontal scale setting. You may use this to determine the signal’s period. The waveform occupies 2.5 horizontal divisions for each cycle.
Is an oscilloscope a voltmeter?
Oscilloscopes do not all function as voltmeters. Depending on the oscilloscope type. In general, a Cathode Ray Oscilloscope (CRO) oscilloscope may be seen as a voltmeter. The possible differences between the two points may be measured using this.
Conclusion
Understanding graphical analysis is essential for reading an oscilloscope screen. One may readily interpret the oscilloscope screen if they are familiar with the fundamental concepts behind the terminology the oscilloscope screen displays.
