Turn on your function generator. It defaults to a sine wave with a frequency of 1000 Hz.

1. Set the Frequency to 90.000 Hz by using the decade buttons (below ?100.000?) to change to the tens place and turning the frequency knob.
2. Turn the voltage knob and set the Amplitude (V_max) to 3.000 V. Record the peak-to-peak voltage (not the amplitude!) and frequency values in far-left section of Table 1.
3. Now, on your oscilloscope, change the Vertical Scale (V/div) setting to something that should allow you to see the signal on the screen. (Hint: You want your 3 V amplitude wave to be as large as possible and have 8 vertical divisions in which to fit it). Set your Horizontal Scale (s/div) setting to something between 500 s and 5 ms per division. Your V/div setting will be in yellow in the lower left corner, and your s/div setting will be in white in the lower right corner. Ignore the time in orange.
4. You should see a sine wave on your screen. If not, adjust the Horizontal and Vertical Scale settings until you do. After getting a sine wave, use the Vertical Scale knob to make the signal as large as possible but still completely visible on the screen. If necessary, you can use the small Position knob in the vertical section to reposition the trace vertically.
5. Next, adjust the Horizontal Scale knob until you see one full cycle on the screen. A good practice here is to use the small Position knob in the horizontal section to put a peak just at the far left of the screen and then adjust the Horizontal Scale setting so that only one more peak appears on the screen.
6. Count the number of divisions on the x axis for one full sine-wave cycle and compute the period T for one cycle from the s/div setting. Then, use the period to calculate the frequency of the signal. Calculate the percent error between your calculated frequency and frequency output by your function generator.
7. Count the number of vertical divisions on the y axis for the peak-to-peak height of the sine wave pattern on the screen. Calculate and record the voltage in Table 1.Calculate and record the percent error between your calculated voltage and the voltage output by your function generator.
8. Record the frequency and voltage measured directly using the oscilloscope measurement tool. Calculate the percent difference between your calculated frequency, and the frequency measured directly using the oscilloscope measurement tool. Also, Calculate the percent difference between your calculated voltage, and voltage measured directly using the oscilloscope measurement tool.
9. You can use the picture posted below " Oscilloscope 90Hz " to record your data for part A.

B. Voltage Measurements at 300 Hz

1. Change the output frequency of the Function Generator to 300 Hz and repeat steps A4-8. Record your results in Table 2.
