PYQ (OSCILLOSCOPE&SIGNAL GENERATOR)

Identify the part of control the left and right movement of the waveform on the oscilloscope screen

• Horizontol Control

• Vertical Control

• Focus Control

• Trigger Control

Choose an advantage of digital oscilloscope

• Familiar Control

• Dedicated control for often used adjustment

• Self calibration

• Instantaneous display updating for real time adjustment

When using an oscilloscope, we need to adjust three basic settings to accomodate an incoming signal to be displayed on the screen. Choose the correct setting

• volt/div knob, time/div knob, trigger level

• volt/div knob,time/div knob, scaleillum knob

• time/div knob, trigger level, scaleillum knob

• volt/div knob, scaleilum knob, trigger level

These are the application of oscilloscope, EXCEPT

• To measure DC and AC voltage

• To measure phase shift between two different waveform

• To measure resistance

• To measure time and frequency

Based on the figure B3(b), calculate peak voltage. Given the vertical scale is 0.2 volt/div and time scale is 50us

• 1.5V

• 0.2V

• 0.3V

• 0.5V

Based on the figure B3(b), calculate peak to peak voltage(Vpp). Given the vertical scale is 0.2 volt/div and time scale is 50us

• 3V

• 0.6V

• 0.5V

• 0.6V

Based on the figure B3(b), calculate periodic time (T). Given the vertical scale is 0.2 volt/div and time scale is 50us

• 120us

• 150us

• 50us

• 60us

Based on the figure B3(b), calculate frequency (f ). Given the vertical scale is 0.2 volt/div and time scale is 50us

• 66.7KHz

• 667Hz

• 6.7KHz

• 6667KHz
