Question

1. Briefly describe the names and important functions of each part of the oscilloscope and function generator.

2. List the advantages and disadvantages of using the oscilloscope as an alternating current voltmeter (AC voltmeter) ‘in detail’.

3. Summarise the names and important functions of the multimeter and power supply parts.

4. Sine wave at function generator

1) When Vpp = 5V, the 1kHz and 10kHz waveforms are displayed.

2) When Vpp = 10V and 1 kHz and 10 kHz waveforms are applied respectively,

Hand-draw how it will look on the oscilloscope screen and explain the difference.

5. Set the square wave instead of the sine wave in question 4 and repeat.

6. Investigate the Lissajous Shape and describe in detail how to measure the Lissajous Shape using an oscilloscope and how to obtain the phase difference.

7. If students A have a 1:1 frequency ratio during the Lissajous Shape experiment, there should be no theoretical change in the shape, but in practice there has been a change. Summarise the reason.
