Excerpt from there:
Oscilloscopes are commonly used to observe the exact wave shape of an electrical signal. In addition to the amplitude of the signal, an oscilloscope can show distortion, the time between two events (such as pulse width, period, or rise time) and relative timing of two related signals. [1]
Oscilloscopes are used in the sciences, medicine, engineering, and telecommunications industry. General-purpose instruments are used for maintenance of electronic equipment and laboratory work. Special-purpose oscilloscopes may be used for such purposes as analyzing an automotive ignition system, or to display the waveform of the heartbeat as an electrocardiogram.
The basic uses of a Cathode Ray Oscilloscope (CRO) include:
1. Voltage Measurement: A CRO can be used to measure the voltage of an electrical signal. By connecting the signal to the input of the CRO, you can observe the waveform on its screen and precisely measure the voltage levels at different points.
2. Time Measurement: A CRO allows you to measure various time parameters of a signal, such as the time period, frequency, and pulse width. By utilizing the time base control on the CRO, you can adjust the time scale and accurately measure these parameters.
3. Waveform Analysis: CROs are widely used for waveform analysis. They provide a graphical representation of signals, enabling you to examine the shape, amplitude, frequency, and other characteristics of the waveform. This analysis is essential in electronics, telecommunications, and other fields where understanding and troubleshooting signal behavior is crucial.
4. Signal Troubleshooting: CROs are invaluable tools for troubleshooting electronic circuits. By observing the input and output waveforms, you can identify abnormalities, locate faulty components, and diagnose circuit problems. This aids in repairing and maintaining electronic equipment.
To utilize a CRO for these applications, follow these steps:
1. Connect the signal source to the input channel of the CRO using a suitable probe or cable.
2. Adjust the vertical and horizontal controls to set the desired scale and position of the waveform on the display. This ensures you can easily observe and measure the signal.
3. Utilize the triggering controls to stabilize the waveform on the screen. Triggers help to synchronize the CRO with the input signal, preventing jitter or instability.
4. Use the appropriate measurement options provided by the CRO to measure voltage, time, and other parameters of the observed waveform accurately.
By following these steps and understanding the functions of a CRO, you can effectively use it for voltage measurement, time measurement, waveform analysis, and signal troubleshooting.
