Time Base
The time base controls the time interval across the scope display.
Voltage Range
The voltage range is the range between the maximum and minimum voltages that
can be accurately captured by the oscilloscope.
Sinusoidal Waveform
This term describes the waveform characteristics typically found in circuits with
large inductance and capacitance, and often referred to as an AC signal. The
waveform alternates either side of 0 volts or may rise and fall creating a regular
sinusoidal shape:

Amplitude
This term indicates the maximum voltage generated from the zero volts line of the
oscilloscope.
Frequency
This term describes the number of signal occurrences per second. Frequency is
measured in Hz (hertz).
Square Waveform
This term describes the waveform characteristics normally generated by signals
switching between clearly defined voltage levels, such as a Hal effect sensor
signal may create by switching a voltage to ground. A typical digital square
waveform is shown below:
