Wentworth Institute of Technology Name: Department of Electronics and Mechanical Date: ELEC 195 - Circuits Theory II Experiment 1 SINUSOIDAL WAVEFORM MEASUREMENTS OBJECTIVE: The objective of this experiment is to make use of Agilent VEE for the control and measurement of ac waveforms. Resume of Theory: For a sinusoidal voltage, the peak amplitude is one half the peak-to-peak value, and the effective or root-mean-square (rms) value is 0.707 times the peak amplitude. The frequency of a waveform is related to its period, T, by f = 1/T. If T is in seconds, then f is the frequency in hertz, (Hz). PROCEDURE: A. Amplitude Measurements. 1. Calculate the peak amplitude and the peak-to-peak value for each of the rms values given in Table 1. Record your results in the spaces provided. 2. Set up the Function Generator and the Digital Multimeter (DMM) on Agilent VEE. On the Function Generator, set the load to Infinity, Function to Sine, and Frequency to 1 kHz. Set the DMM to measure ac Volts. This will read the rms value. 3. Connect the Oscilloscope and the DMM to measure the output of the Function Generator. 4. Set the output Amplitude of the Function Generator to each of the rms values indicated in Table 1, and record the corresponding Multimeter reading in the DMM rms column. 5. On the oscilloscope, determine each peak-to-peak value using two methods. First multiply the number of divisions deflection (the vertical distance from bottom to top of waveform) by the number of volts per division. Record your results in Table 1. 6. Next, use the Measure, Voltage, P-P feature of the oscilloscope. This gives you a readout of the peak-to-peak value of the voltage at the bottom of the oscilloscope display. Record this value in the last column of Table 1. Table 1: Amplitude Measurements B. Period and Frequency Measurements. 7. Calculate T, the period for each of the frequencies listed in Table 2. 8. Use Agilent VEE to obtain a 5 VP-P sine wave, and set the frequency to each of the values listed in the table. 9. At each frequency, Autoscale the oscilloscope, read the number of divisions in one cycle, and the time/div displayed on the screen. Enter these values in Table 2. 10. Calculate the period, T = (div/cycle) x (time/div), and then calculate the frequency, f = 1/T, and record these values in the table. 11. At each frequency, press the Time button in the set of three Measure buttons at the top center of the oscilloscope front panel, and then press the button under Frequency at the bottom of the display. Read the resulting frequency, and record in the rightmost column in Table 2. 12. Use Microsoft Word to write a brief conclusion for this experiment.
