The maximum value observed
from a series of measured results
for the selected automatic
measurement items.
Standard
Deviation
The variance of the currently
measured value from the mean.
The standard deviation equals the

severity of jitter in a signal.
The number of samples used to
determine the standard deviation
can be user-defined.
