Snapshot executes all of the single waveform measurements once; the measurements are not
continuously updated. Any measurements previously taken are retained on the display until you
complete a new snapshot. To take another snapshot, click the Snapshot Again button.
Things to consider when taking snapshots:
• Before taking a snapshot, be sure to properly display the waveform. Snapshot does not warn you
if a waveform is improperly scaled (clipped, low signal amplitude, low resolution, and so on).
• To change the source for taking a snapshot, select another channel, math, or reference memory
waveform, and then execute snapshot again.
Measurement Statistics Control Window
Access this control window from the Measurement Setup control window. You can also access statistics
from the Measure menu Statistics submenu.
Overview
Use the Measurement Statistics control window to display statistical calculations on
measurements. The control window contains controls that determine which statistics are displayed
in the measurement window.
To Use
Click Off to turn the measurement statistics display off.
Click Mean to display the value and the mean (µ) of each
measurement. Click All to display all statistics for each
measurement value (mean (µ), minimum (m), maximum
(M), standard deviation (σ), and population (n)). Use the
multipurpose knobs to set the statistics weight. Click Reset
to restart the statistics calculations.
Select the individual statistics directly from the Measure
menu Statistics submenu.
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
there 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.
All statistics (mean, minimum, maximum, standard deviation, and population) are always gathered
even though the mean may be the only statistic shown. When measurements are turned on, the
acquisitions take longer because measurements and statistic calculations are done on each
acquisition.
