Analog and Digital Oscilloscopes (ATI04)

This comprehensive INVOLVEĀ® interactive multimedia training program was produced in association with the Instrument Society of America (ISA).

This four-lesson program trains participants on the principles and procedures of various test devices.


This lesson is designed for participants familiar with process control principles and instruments. An understanding of basic algebra is also recommended.


This lesson presents the operating principles and procedures for using analog and digital oscilloscopes. The lesson also provides an understanding of how these test devices work, the functions performed, and how they are utilized. Procedures for using an oscilloscope to measure amplitude, period, and frequency are also demonstrated.


Identify the major sections of an oscilloscope and their functions. Describe the function of the vertical input connector and coupling switch. Describe the functions of the vertical gain control and of the vertical position. Describe the operation of the trigger and the function of a probe. Describe the advanced features of a digital oscilloscope. Set up an oscilloscope. Identify and interpret typical examples of characteristic waveforms. Describe the amplitude, frequency, and period of a waveform. Measure amplitude, period, and frequency using analog and digital oscilloscopes.
