Measurement Statistics
After you add a parameter measurement, you can look at statistics of that
parameter measurement, and acquire an understanding of how that
measurement changes with time.
Statistics accrue with each additional trigger until pressing Clear Sweeps (either on
the front panel or in the Measure dialog), or changing a control (e.g. Volts/Div).
Most statistical values (mean, minimum, max, standard deviation) are self-
explanatory. Num is the number of measurements in the statistical sample. Value
and Status are defined in Understanding Parameter Displays (previous).

Sometimes you might want a parameter measurement on a
specific portion of your signal, and ignore all other portions.
When this is the case, you can use Measure Gate. Measure Gate
is controlled in the Measure dialog, and is set in grid divisions.
Set the gate by touching the Start field to highlight the control
(shows in yellow), and then use the adjust knob to dial the
location of the start gate. Repeat the same process for the Stop
gate. Measure gates remain on the display provided the Start
gate is not equal to 0 divisions, and the Stop gate is not equal to
10 divisions.
View measurement statistics by checking the box next to On
under Statistics in the Measure dialog. If a measurement is
displayed, statistics are also shown (as follows).
