• Voltage scale

• Power button

What does the probe connected to an oscilloscope do?

• Prints the waveform

• Captures the electrical signal from a circuit

• Cleans the oscilloscope screen

• Measures temperature

Which control adjusts how much time is displayed on the screen?

• Vertical scale control

• Time base control

• Trigger control

• Intensity control

What happens when you increase the volts/div setting on an oscilloscope?

• The waveform looks shorter.

• The waveform moves to the right.

• The waveform looks taller.

• The waveform becomes invisible.

Which control on an oscilloscope adjusts the time interval displayed across the horizontal axis?

• Vertical position control

• Time base or horizontal scale control

• Trigger level control

• Voltage scale control

What type of waveform is typically produced by a DC signal?

• Sinusoidal

• Input coupling

Which of the following describes a trigger function on an oscilloscope?

• It determines the signal's amplitude.

• It freezes the display for static observation.

• It adjusts the signal's frequency.

• It ensures the waveform starts at a specific point for consistent display.

In an oscilloscope's control panel, what does the AC/DC coupling switch do?

• Turns the device on or off.

• Filters the signal to show only AC or DC components.

• Adjusts the brightness of the screen.

• Inverts the signal on the display.

What does the intensity control on an oscilloscope adjust?

• The brightness of the waveform display

• The time per division on the horizontal axis

• The amplitude of the signal

• The bandwidth of the oscilloscope
