The Oscilloscope
The Oscilloscope
Objectives:
1.To become familiar with the construction and use of the oscilloscope.
2.To gain experience in making simple measurements using this equipment.
Materials and Equipment Needed: Dual Trace Oscilloscope with probes
Instructions:
Please read this experiment carefully so when you come to the lab you understand some of the basic ideas of an oscilloscope. Become familiar with the documentation for this experiment and the location of the various buttons and knobs on the oscilloscope.
Throughout this lab there are capitalized words and abbreviations which refer to the controls (knobs, buttons, dials, ect.) on the instrument.
Upon completion of this lab the student will be able to: 1. Use an oscilloscope and manipulate the controls to display various signals. 2. Measure the frequency, period, and amplitude of a signal with the aid of an oscilloscope. Introduction: The oscilloscope is one of the most useful tools in electronics. Unlike simple meters, the oscilloscope provides a visual picture of the waveform being investigated from which measurements of amplitude frequency, phase, ect. can be made. The scope displays an accurate reproduction of the waveform being analyzed by causing an electron beam to draw a graph on the inside of a phosphor coated screen. The waveform stands still because the graph is drawn repeatedly and because of the persistence of the phosphors and the human eye. The vertical axis of the screen is calibrated in volts and the horizontal axis is calibrated in units of time.
The word oscilloscope comes from the words “oscillo” short for oscillation and “scope” a Greek word for an “instrument for viewing.”
There are a number of different types of scopes however most modern scopes are digital. This means that the input signals are first sampled and converted to a digital format. An onboard microprocessor can then be used to perform the desired manipulations on the signal. The onboard processor allows many
