5.14.2 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.
• 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.

5.14.3 Integ BW
Press Integ BW to specify the range of integration used in calculating the power in the
channel, for example. set the main (center) channel bandwidth. Note that the integration
bandwidth is displayed on the trace as two markers connected by an arrow. Be sure the
Span of the instrument is set between 1 and 10 times the integration bandwidth.

Key Notes: If RRC Filter is on, the actual integration bandwidth used is the displayed
integration bandwidth multiplied by (1 + “Filter Alpha”).
