
Vpp - Difference between highest and lowest points in the
waveform.

Vmax - Measures highest point in waveform. Unlike top, it
does not assume the waveform has two levels.

Vmin - Measures the lowest point in a waveform. Unlike
base, it does not assume the waveform has two levels.

Mean - Average of the data for a time domain waveform.
Computed as centroid of distribution for a histogram.

Vrms - Root Mean Square of data between the cursors -
about the same as sdev for a zero-mean waveform.

Crms - Cyclic root mean square: Computes the square root
of the sum of squares of data values divided by number of points.
Contrary to rms, calculation is performed over an integer number of
cycles, eliminating bias caused by fractional intervals.

Vtop - Higher of two most probable states, the lower being
base; it is characteristic of rectangular waveforms and represents
the higher most probable state determined from the statistical
distribution of data point values in the waveform.
