The function of the oscilloscope applications and types of characteristics
Functional characteristics of oscilloscope
Oscilloscope is an electronic instrument used to display and observe signal waveform and related parameters, which can observe and directly measure the shape, amplitude and period of signal waveform, and its shape is shown in the figure. All electrical parameters or physical quantities that can be converted into electrical signals can be converted into equivalent signal waveforms for observation, such as current, electrical power, impedance, temperature, displacement, pressure, magnetic field, etc.
The oscilloscope can display the voltage waveform and current waveform in the circuit directly on the oscilloscope, and determine whether the equipment being tested is faulty according to the displayed waveform shape, frequency, period and other parameters. If the waveform is normal, indicating that the circuit is normal; if the signal frequency, phase distortion, it is not normal, with the oscilloscope to measure a variety of AC signals, digital pulse signals and DC signals, maintenance efficiency, easy to find the point of failure.
The practical application of oscilloscope
Oscilloscope is often used in the production of electronic products debugging and maintenance field, generally by observing the signal waveform displayed by the oscilloscope to determine whether the circuit performance in line with factory requirements or in the maintenance of the circuit to determine whether it is normal, etc..
Oscilloscope in the maintenance of induction cooker applications
In the maintenance of induction cookers, often use the oscilloscope for testing. Usually can be used in the maintenance of induction cooker control circuit board oscilloscope detection control circuit in the integrated circuit output signal waveform, according to the signal waveform to determine the circuit is good or bad, as shown in the figure.
Application of oscilloscope in the repair of monitors
When repairing the main circuit board of the monitor, an oscilloscope can be used to detect the signal waveform output in the main circuit, and to repair and judge according to the signal waveform. Use an oscilloscope to detect the signal waveform radiated from the periphery of the step-up transformer in the inverter circuit, as shown in the figure.
Application of oscilloscope in repairing TV sets
In the process of repairing a TV set, the waveform of the TV set is detected with an oscilloscope, so that the repair and judgment can be made based on the signal waveform. As shown in the figure is to detect the line pulse signal waveform radiated by the line return transformer.
Oscilloscope in the production of debugging applications
Oscilloscope is often used in the production and debugging of electronic and electrical products, such as the figure, for the production of tuner debugging site due to the tuner for high-frequency devices, the need to adjust the internal coil to achieve the required frequency requirements, it is necessary to use the oscilloscope to monitor the waveform before and after the adjustment, the waveform to achieve the corresponding amplitude and shape, that is, the completion of the debugging of the electronic products.
