Top
The Top of a waveform is the mode (most common value) of the upper 
part of the waveform. If the mode is not well- defined, the Top is the same 
as Maximum. 
Base
The Base of a waveform is the mode (most common value) of the lower 
part of the waveform. If the mode is not well- defined, the Base is the 
same as Minimum. 
Maximum
Maximum is the highest value in the waveform display. 
Minimum
Minimum is the lowest value in the waveform display.
Peak-to-peak
Peak- to- peak is defined as the difference between maximum and minimum 
values. 
RMS
RMS (DC) is the root- mean- square value of the waveform over one or 
more full periods. If less than one period is displayed, RMS (DC) average 
is calculated over the full width of the display.
