5.16.2 Avg Mode
Press Avg Mode to select the type of termination control used for the averaging function to
either Exp or Repeat. This determines the averaging action after the specified number of
measurements (average count) is reached.
• EXP (Exponential Averaging mode)—When you set Avg Mode to Exp, each successive data
acquisition after the average count is reached is exponentially weighted and combined
with the existing average. Exponential averaging weights new data more than old data,
which facilitates tracking of slow-changing signals. The average will be displayed at the
end of each sweep.
