DEE10133 CHAPTER 2: OSCILLOSCOPE

Choose the first step to be done to make that the oscilloscope is in good condition?

• Select a suitable range of volt/div

• Select the input channel ti channel 1

• Calibrate the oscilloscope

• Change the probe of oscilloscope

The amplitude of an oscilloscope is 6 division and the volt/div knob is set at 2V/div. Identify the value of the amplitude in volt.

• 3V

• 1.2V

• 0.3V

• 12V

If the vertical attenuation is set 2V/div and the time/div control is set 1ms, calculate Vpp= ​ ​

• 16Vpp
• 10Vpp

If the vertical attenuation is set 2V/div and the time/div control is set 1ms, calculate time of 1 cycle (T) ​ ​

• 12ms

• 2ms

• 5ms

• 10ms

If the vertical attenuation is set 2V/div and the time/div control is set 1ms, calculate phase angle

• 100

• 144

• 72

• 60

If the vertical attenuation is set to 2.5V/div and the time/div control is set at 100us, calculate the period,T

• 150us

• 400us

• 200us

• 300us

The amplitude of an oscilloscope is 4 division and the volt/div knob is set at 0.5V/div. Determine the value of Vp

• 0.01V

• 0.1V

• 1.0V

• 10V

Identify the part to control up and down movement of the waveform on he oscilloscope screen

• Horizontal control

• Vertical control
