Average Type
Enables you to control the way averaging is done by choosing one of the following
averaging scales: Log-Power (Video) or Power (RMS).
There are three different averaging processes in the measurement, and all of them
are affected by this setting: Trace Averaging, the Average detector, and VBW
filtering.

LOG
Simulates the traditional spectrum analyzer type of averaging by
averaging the log of the power
Power (RMS)
RMS
True power averaging that is equivalent to taking the RMS value of the
voltage. This is the most accurate type of averaging

Meas Type
Selects either EXAMine or FULL measurement type. This parameter is coupled to
"Average Mode" on page 1432. Therefore, if the EXAMine measurement type is
selected, the measurement sets the Average Mode to exponential. If the FULL
measurement type is selected, the measurement sets the Average Mode to repeat.
The behavior of each measurement type is described in the table below. When
averaging is on, trace averaging is used as each active range is measured.
Averaging is not used at any other time.
