Behavior
Measurement values continue as live updates while the statistics accumulate over time. The statistics
appear on the main screen when a control window is open or on the right side of the screen when no
control windows are open and t here are less than four measurements active. The color of the statistics
match the color of the waveform from which the measurement was taken.
The statistics weight specifies the constant used to calculate the mean and standard deviation; the minimum
and maximum values are unaffected by weighting. A large value produces statistics that vary less over time.
