Unit II

Time and Instruments:

There is no doubt that oscilloscopes and the caesium clock changed the world as we know it. When engineers developed accurate clocks and combined that technology with amp and voltmeters we developed some of the most useful tools out there for electrical engineering.


Clocks: Begin your lesson with three major types of clocks. Time keeping devices are found within almost all electronics today and are one of the keystones of modern technology.

Electronic Test Equipment: This stuff makes the amazing possible. Learn about Oscilloscopes, Time Interval Counters and Spectrum Analyzers.

Radio: The use of changing frequencies over time is the basis of radio signals and computer signals. The area of radio and computers has its own set of test equipment which you will learn about in this course when this section is complete.
