You will be required to use the ELVIS system to produce and measure different signals. 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. 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 as you read through these lab instructions. 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 Measure the voltage at the +5V output on the ELVIS Prototyping breadboard. Voltage at +5V: _____ This should demonstrate 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 Use the following values in the circuit shown throughout this part of the lab. Ω= k 101R Ω= k 332R Ω= k 103R V7=+V 1R 2R 3R +V 0V 2 PRE-LAB: Calculate the ideal values of V0 and the currents through each resistor. Show your work. V0:_____ I1:_____ I2:_____ I3:_____ LAB PROCEDURE: Use the DMM to measure the exact values of each resistor. R1:_____ R2:_____ R3:_____ Construct the circuit as shown. Use the Variable Power Supplies to produce V+. Make sure you measure this with the DMM and readjust until the supply is as close as possible to 7 V and record value. Use the DMM to directly measure V0, and the currents through each resistor. V+:_____ V0:_____ I1:_____ I2:_____ I3:_____ Can this differentiation from the ideal values calculated in pre-lab be explained by the exact values of the resistors? Calculate what the currents should be with your measured V0 and the exact resistors. Show your work. I1:_____ I2:_____ I3:_____
