T-Max and T-Min
T-Max and T-Min are x-axis time values at the first displayed occurrence of the 
waveform maximum and minimum respectively, starting from the left side of the 
display. 
Voltage measurements
Amplitude, Base, Maximum, Minimum, Peak to Peak, Top
The amplitude of a waveform is the difference between its top and base values.
The base is the mode (most common value) of the lower part of the waveform, or 
if the mode is not well defined, the base is the same as minimum.
Maximum and minimum are the highest and lowest values in the waveform 
display respectively.
The peak-to-peak value is the difference between maximum and minimum values.
The top is the mode of the upper part of the waveform, or if the mode is not well 
defined, the top is the same as maximum.
