Hoffbeck and Dr. Aziz S. Inan Lab Experiment #1: Introduction to the Lab Equipment - p. 2 of 5 - Introduction to the Lab Equipment I. Objective At the completion of this experiment, the student should be able to use the function generator to produce any specified signal, use the oscilloscope to measure the amplitude, period, and frequency of periodic signals, and use the digital multimeter (DMM) to measure the average value (D.C. value) and the RMS value (A.C. value) of a signal. II. Introduction Being able to use lab equipment to verify that a circuit is operating correctly or to determine the reason a circuit is malfunctioning is an important and useful skill for engineers. In this experiment, the student will learn how to use a function generator (or sometimes also called a signal generator), which is used to generate test signals for a circuit, an oscilloscope (sometimes simply referred to as a scope), which is used to examine signals and to take measurements on them, and a DMM, which is used to measure the average value and RMS value of signals. For example, to verify that an amplifier is working, a function generator could be used to generate an appropriate input signal, the oscilloscope could be used to examine the output signal for noise, and the DMM could be used to measure RMS value of the input and output signals in order to calculate the gain of the amplifier. III. Procedure Part 1: Background Reading Read the attached introduction to the oscilloscope, signal generator, and DMM, and answer the following questions: 1. The oscilloscope display is a graph of what quantity versus what quantity? 2. What is the difference between DC coupling and AC coupling on the oscilloscope? 3. Should DC coupling or AC coupling be used for most measurements on the oscilloscope? Why? 4. What happens if a signal is not triggered properly on the oscilloscope? 5. What is the signal generator used for? 6. What aspect of the signal does the Offset knob change on the signal generator? 7. What aspect of the signal does the DMM measure when it is in the D.C. volts mode? 8. What aspect of the signal does the DMM measure when it is in the A.C. volts mode? Part 2: Measure the Calibration Signal on the Oscilloscope
