Understanding the Components of an Electronic Oscilloscope
Display: The display on an oscilloscope is where the waveforms are visualized. It typically consists of a grid with a horizontal time axis and a vertical amplitude axis.
Time Base: The time base controls the horizontal scale of the display. It determines the time interval represented by each division on the screen.
Vertical Gain: The vertical gain controls the amplitude scale of the display. It determines the voltage represented by each division on the screen.
Trigger: The trigger is used to synchronize the oscilloscope’s display with the input signal. It allows the user to capture specific events or patterns in the signal.
Probes: Probes are used to connect the oscilloscope to the electrical circuit under test. They provide signal conditioning and ensure proper impedance matching.
