Specifically, it provides students an opportunity to become familiar with the ELVIS integrated instrument suite. Pre-Lab (BEFORE coming to lab) 1. Read through all lab procedures on this sheet. Be comfortable with everything that you will have to do during the lab. 2. Read through the ELVIS User’s Guide posted on the class website. Be familiar with all of the ELVIS components that you will have to use during the lab. 3. Calculate any values and answer all questions indicated. NOTE: In all future labs you will have work to turn in as soon as you walk into lab. You will not be allowed to do this work during lab time. Part 1 Lab Procedure Use a hand-held digital multimeter (DMM) as well as the ELVIS DMM and measure the voltage at the +5 V output on the ELVIS Prototyping breadboard. Handheld DMM Voltage:_____ ELVIS DMM Voltage:_____ This demonstrates to you that you cannot trust the ELVIS components to produce exactly what is displayed on the computer screen. Measure these outputs using the DMM or Oscilloscope before using them. Part 2 Pre-Lab (Before coming to the lab) Use the following values in the circuit shown throughout this part of the lab. Calculate V0 and the currents through each resistor assuming ideal resistors. Show your work on the next page. 055:041 Electronic Circuits Fall 2008 5 Now calculate the new value of capacitance based on your reactance measurement. This involves the measurement frequency used by the Impedance Analyzer. C: _____ Use the Function Generator to produce a sine wave with amplitude 2 V peak-to-peak and frequency 100 Hz. Again, measure the Function Generator’s output, using the Oscilloscope, and readjust until you see the desired waveform. Now connect the Function Generator output to the rest of the circuit. Keep this displayed on Ch. 1 of the Oscilloscope, and display V0 on Ch. 2. Now you can measure the gain and phase difference between the input waveform and the output. Change the frequency of the input, and fill in the following table: Frequency (Hz) Gain ( ) iV V0 Gain (dB) Phase (degrees) 10 50 100 500 1,000 5,000 Now hook up the Bode Analyzer to this RC-circuit and you will be able to see the full curve for both Gain and Phase difference. Make sure to adjust the Frequency settings so that you can see the full curve. Be sure to show the T.A. or instructor your plot. Does your result confirm what type of filter you thought this circuit was? If not, what type of filter does it now appear to resemble? Once the analysis is completed, save the Bode plots to your desktop. In the future, this will be a useful tool for including plots in your lab report. 055:041 Electronic Circuits Fall 2008 6 Grading Prelab Are the pre-lab values calculated?
