One-Button Measurement Functions
5.27.2 Avg Mode
Selects the type of termination control used for the averaging function (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.
• Repeat—When you set Avg Mode to Repeat, after reaching the average count, all previous
result data is cleared and the average count is set back to 1.

5.27.3 Range Table
Enables you to enter the settings for up to 20 ranges, either using the instrument front
panel keys or remotely. Upon entering the range table, the measurement stops, then the
analyzer is set to a constantly sweeping idle state. The analyzer is then set to the current
values for range 1 (whether range 1 is on or off). If a range is currently off, the values in the
range table for that range are replaced with --- (see Range 5 in the illustration) to
