Name Name TA Section EE 100 Experiment 2 Oscilloscope Lab Report This write up follows along with the Hands On section of the lab It requires you to draw some of the signals you ll observe on the oscilloscope and to correctly understand the concepts of amplitude and frequency You should complete this report as you do the lab exercises III Hands On a Graphing a signal on the oscilloscope 1 Draw the signal on the scope obtained after step 3 Please specify the amplitude frequency and period On the voltage y and time x axes you should label units appropriately Indicate the trigger location Amplitude Frequency Period 2 Draw the signal on the oscilloscope obtained after step 5 Please specify the amplitude frequency and period On the voltage y and time x axes you should label units appropriately Indicate trigger location Amplitude Frequency Period 1 3 Draw the signal on the oscilloscope obtained after step 7 Please specify the amplitude frequency and period On the voltage y and time x axes you should label units appropriately Amplitude Frequency Period 4 After step 7 how many peaks max points are there in the oscilloscope s field of view How many minimum points b Triggering 1 Please answer the question addressed in step 5 What happens when the trigger level is beyond that of the signal Why 2 Please answer the question addressed in step 6 What happens now when the trigger level is beyond that of the signal Why 3 On step 8 explain what is happening when the trigger source is changed from A1 to A2 To the best of your ability draw the curves you see When trigger source is A1 2 When trigger source is A2 4 For the previous question measure the amplitudes of the input A1 and the output A2 sinusoids What is the phase shift between the two signals Amplitude of input A1 Amplitude of output A2 Phase Shift degrees 5 Based on step 11 does the RC circuit pass low frequency signals or high frequency signals Explain how you can tell c More Fun Stuff 1 Disconnect the ground from your oscilloscope probe remove the probe clip if there is one and touch the tip of the probe to your finger be careful the probe tip is sharp like a tack With your finger touching the probe tip hit the Autoscale button What kind of waveform do you see What s the frequency of this waveform Where is it coming from Are you generating electricity Hint in Europe the frequency of the signal you see would be 5 6 of what you see here in North America Answer as many of these questions as you can 2 Draw the voltage signal created from sound by a speaker microphone or buzzer Watch the waveform across the device as you change the frequency of the generator Please state which device you are using and try to figure out what the frequency range of the device and your hearing might be 3
