An oscilloscope presents electrical information in the tiime domain. That is the basic function of a scope. This means that it converts the input signal to an x-y graph where x is the time and y is the amplitude of the input. The line seen on the scope is called the trace. The time it takes to go from the left to the right of the screen is the time base. In a scope you can adjust the time base from up to a few seconds to a few nano seconds. Varying this time base gives users the ability to analyse the signals at different frequencies.
