VOLTS/DIV
Determines how many volts the signal at the input must swing for the trace to move one division.
VRMS
The rms voltage of an AC source represents the required DC voltage to generate the same amount of
heat in a resistor as the AC source would do. For sinusoidal signals, Vrms = Vpp / sqrt(2).

WAVE
The generic term for a pattern that repeats over time. Common types include: sine, square,
rectangular, saw-tooth, triangle, step, pulse, periodic, non-periodic, synchronous, asynchronous.
WAVEFORM
A graphic representation of a voltage varying over time.
WAVEFORM POINT
A digital value that represents the voltage of a signal at a specific point in time.
