Question

2. One of the first things you are asked to do in the experiment is to display a 1 kHz sine wave signal on the screen. Write down the for- mula relating frequency to period. What is a reasonable setting for the "Time/div, dial? What would you see if you set the dial on 1 μsec/div? 100msec/div?

Answer 1

Formula relating frequency to period frequency = 1/Time period Time/div dial is used to see the waveform clearly. If frequency of the waveform is very large or very low then the display of the waveform on the screen is very wide or very narrow. So we use the Time/div dial to make the waveform in proper wave. If we get the dial on 1 u sec/div then our waveform become narrow than previous Let for time/div = 1 m sec/div then This will be for Time/div = 1 u sec/div \r\n If Time/div = 1 m sec/div then Time/div = 100 m sec/div If Given time/div scale have lower voltage then the waveform becomes more narrow than previous. If the time/div scale have larger value then the waveform becomes more wide than previous.
