EET118Laboratory Experiment #1_C
Dr. J. Fiorillo Multisim
Objective: The objective of this experiment is to introduce the Multisim simulation software and how it can be used to simulate DC Operating Conditions of various circuit configurations.
List of Equipment\Software:
• Multisim Software Education Edition 14.2: National Instruments
• EET118Laboratory Multisim Manual: Dr. Fiorillo
• Microsoft Word and Snipping Tool: Microsoft
Learning Objectives:
• Students will learn how to configure the Multisim simulation software for EET118
• Students will learn how to simulate resistance, current, and voltage measurements with the Agilent 34401A Multimeter provided with Multisim in various circuit configurations.
PART A: Procedure: Multisim SimulationsFigure #1
STEP #1 Use the Multisim Editor to construct the circuit described in Figure #1 in Table #1A. Save the file in the format described in EET118Laboratory Multisim Manual.
STEP #2 Run a Multisim Interactive Simulation with the Agilent 34401A DMM to obtain the branch currents in Figure #1, I(R1), I(R2), I(R3), and I(V1). Note, this step requires that four DMMs be included for the simulation. Refer to class notes and illustrations provided in the EET118Laboratory Multisim Manual.
STEP #3 Run a Multisim DC Operating Point analysis to obtain the branch currents I(R1), I(R2), I(R3), and I(V1).
STEP #4 Use the Snipping Tool to copy and paste the results from Steps #2 and #3 in the space provided in Data Table #1B.
STEP #5 Run a Multisim Interactive Simulation with the Agilent 34401A DMM to obtain the voltage drops V(R1), V(R2), and V(R3). Note, voltage drops must
be expressed in terms of node voltages for this step. i.e. V(a)V(b). This step requires that three DMMs be included for the simulation.
STEP #6 Run a Multisim DC Operating Point analysis to obtain the voltage drops V(R1), V(R2), and V(R3). Note, voltage drops must be expressed in terms of node
voltages for this step.
STEP #7 Use the Snipping Tool to copy and paste the results from Steps #5 and #6 in the space provided in Data Table #1C.
STEP #8 Run a Multisim Interactive Simulation with the Agilent 34401A DMM to obtain the node voltages V(A), V(B), V(C), and V(0). This step requires that four DMMs be included for the simulation.
STEP #9 Run a Multisim DC Operating Point analysis to obtain the node voltages V(A), V(B), V(C), and V(0).
STEP #10 Use the Snipping Tool to copy and paste the results from Steps #8 and #9 in the space provided in Data Table #1D
STEP #11 Run a Multisim Interactive Simulation with the Agilent 34401A DMM to obtain the node voltages V(CA) and V(CB). This step requires that two DMMs be included for the simulation.
