Key Access:
Meas Setup
Avg Number
On Off
Press Avg Number (On) to specify the number of averages used when
calculating the measurement result. The average will be displayed at
the end of each sweep.
Avg Number (Off) disables measurement
averaging.
Key Access:

Avg Mode
Exp Repeat
Allows you to select the type of termination control used for the
averaging function. This determines the averaging action after the
specified number of measurements (average count) is reached.
Avg Mode has no effect on measurements that are not averaged.
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.
Repeat After reaching the average count, all previous result
data is cleared and the average count is set back to 1.

Meas Setup
Avg Type
Video Power
Allows you to specify the type of result averaging to be performed.
Video Selects averaging that sums the trace data and divides
by the number of data .
Power Selects averaging that converts trace data from dBm to
power units, then averages the power trace data. This
selection requires more time to perform.
Key Access:
Meas Setup
Threshold Lvl
Abs Rel
Allows you to set the level above which the mean carrier power
calculation is based upon. The threshold level may be described in dB
(relative to the carrier) or dBm (absolute).
