Laboratory 5: Oscilloscope

201013

Laboratory #5:

Oscilloscope

Objectives:

This laboratory exercise introduces the operation and use of the oscilloscope.

Introduction:

The oscilloscope is an instrument for the analysis of electrical circuits by observing voltage and

current waves. It may be used to study wave shape, frequency, phase angle, and time, and to

compare the relation between two variables directly on the display screen. Perhaps the greatest

advantage of the oscilloscope is its ability to display shapes of both periodic and single-shot

waveforms being studied.

Pre-Lab Preparation:

Review Appendix A: Safety

Read Appendix B: Equipment and Instrument Circuits through “Digital Storage Oscilloscope”.

Pay special attention to “Oscilloscope Grounding Errors”.

Read Appendix D, Operating Instructions for a Typical Oscilloscope.

Read Appendix E, Tektronix TDS1002B Digital Storage Oscilloscope.

Equipment Needed:

 AC power supply (Autotransformer)

 DC power supply

 Multimeter, Digital

 Resistance boxes (2)

 Function generator

 Oscilloscope, Dual Beam

Procedure:

1. Frequency Measurement: Adjust the function generator to have an output voltage between 5

and 10 volts. Use the oscilloscope to measure the frequencies generated by the function gen-

erator at settings of 50, 500, 5000, and 50,000 Hz, and record the results in your lab note-

book. Compare the source’s settings with the scope-measured values.

2. Effect of Input Resistance: Construct the following circuit, using the DC power supply for

the power source. Set the DC power supply’s output to about 10V.
