So far, the basic controls of the oscilloscope and their functions
have been discussed, as well as the initial setup of those
controls that must be accomplished prior to turning on the scope.
You are now ready to turn on the oscilloscope.
In the next learning event, how to turn on and adjust the
oscilloscope for a single trace will be discussed. Then, you will
learn how to measure the voltage amplitude and frequency of a
signal by using the screen grid.
