Set the Average Mode

[:SENSe]:OBWidth:AVERage:TCONrol?
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.

Set OBW Span
[:SENSe]:OBWidth:FREQuency:SPAN <freq>
[:SENSe]:OBWidth:FREQuency:SPAN?
Enables you to specify the range of integration used in
calculating the total power from which the percent occupied
bandwidth is then calculated. The analyzer span will be set
to the same value as the OBW Span for the measurement.
OBW Span should be set to approximately 2 times the
expected occupied bandwidth result.
If you have an adjacent channel, you should not set the OBW
span to 2X your occupied bandwidth. The OBW
measurement first computes all the power in the span and
then 99% of that. Diamond markers are set around the
