1.3 Introduction to VirtualBench Getting Started Guide Lab Exercises
The VirtualBench Getting Started Guide includes three example exercises to help you learn the basics of VirtualBench
and integrate its unique capabilities into your laboratory. These three exercises, outlined below, are common in an
introductory analog circuits class.
Note that these exercises are designed to help you gain a better understanding of how to operate the VirtualBench
device.
Section 2: Take Circuit Measurements With the Digital Multimeter and Function Generator
In this exercise, simulate and physically build a resistive circuit to compare theoretical and actual power measurements.
The section includes using the following:
● Function generator to provide both DC and AC signals
● Digital multimeter to calculate DC and AC power
Section 3: Function Generator and Mixed-Signal Oscilloscope
In this exercise, simulate and physically build an amplifier and RC circuit to compare theoretical and actual behavior. The
section includes using the following:
● Function generator to alter the type of input applied to the physical circuit
● Power supply to power the physical circuit
● Oscilloscope to acquire and analyze the output waveform
Section 4: Programmable DC Power Supply
In this exercise, simulate and physically build the amplifier circuit from exercise 1 to compare theoretical and actual
behavior when using selected values for the DC power supply. The section includes using the following:
● Power supply to power the physical circuit with selected DC power
● Function generator to supply a waveform to the physical circuit
● Mixed-signal oscilloscope to monitor the input and output of the physical amplifier circuit
1.4 Multisim Circuit Simulation in the Laboratories
Throughout these laboratories, discover how you can use circuit simulation as part of your teaching approach. All circuit
topologies are defined and simulated using Multisim, an integrated schematic capture and SPICE simulation
environment developed specifically for educators and students.
