Voltage Measurement Parameters
First select a Source Channel for your Voltage measurement parameter by
pressing the Source option button. Now, use the Type option button to choose
from the following Voltage measurement parameters for your selected source.

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.
