Oscilloscopes

Test your knowledge

Try answering the following questions:

1) Which of the following statements best

    describes the functions of an oscilloscope?:

    A) An oscilloscope is a test instrument that

         interrogates the fault memory of vehicle

         electrical systems.
    B) An oscilloscope is a diagnostic scan tool that    

         displays electrical faults as a graph on a 

         screen.
    C) An oscilloscope is a test instrument that 

         displays the shape of electrical signals as a

         waveform on a screen.

    D) An oscilloscope is a diagnostic tool that can 

         detect electrical faults in a waveform and

         display them as a graph.

2) Which of the following test measurements are 

    displayed on an oscilloscope screen?:

    A) Ohms down the side and frequency along the

         bottom.

    B) Time down the side and voltage along the

         bottom.
    C) Frequency down the side and time along the

         bottom.

    D) Voltage down the side and time along the

         bottom.

3) What is the purpose of the trigger function of an

    oscilloscope?

    A) It allows the user to switch the scope on and 

         off automatically.

    B) It enables the oscilloscope to display a stable

         waveform on the screen.

    C) It changes the scale of the oscilloscope to an

         auto ranging mode.

    D) It enables the oscilloscope to generate trigger

         signals to actuators.

4) What is the main advantage of an oscilloscope

    compared to a digital multi meter?

    A) It has a higher sample rate and can display

         high frequency electrical signals.

    B) It has a lower sample rate and can

         accurately display high frequency electrical

         signals.

    C) It has a low sample rate that can detect low

         voltage signals.

    D) It has a higher sample rate that can

         automatically detect the voltage scale of the

         signal.

5) Which of the following statements best describes     the oscilloscope waveform shown in the picture     below?:     A) It is an AC waveform generated by a Hall effect            sensor.     B) It is a digital control signal to energize an actuator.     C) It is a trigger signal to energize an inductive pulse          sensor.     D) It is a sinusoidal waveform created by an inductive          pulse generator.
