Description:
When you select ON, each trace represents the combined results of several measurements, and the
averaging function specified in AVER:TYPE determines how results are combined.
RMS averaging (AVER:TYPE RMS) provides a better estimate of the noise in measurement data. Vector
averaging (AVER:TYPE TIME) reduces the amount of random noise and provides a better estimate of
the repetitive signals in the measurement data. Maximum averaging (AVER:TYPE MAX) saves the
maximum power value (power spectra) for each frequency bin.
When you select OFF, each trace represents the results of a single measurement. It is mathematically
equivalent to exponential RMS (power) averaging with 1 average.
When averaging is ON and AVER:TYPE is MAXimum, RMS or TIME, INIT:IMM sets the No Pending
Operation (NPO) flag to 1 after the specified number (set with the AVER:COUN command) of
measurement results have been combined. When averaging is ON and termination control is exponential
(AVER:TCON EXPO), INIT:IMM sets the NPO flag to 1 each time a measurement is completed, after
the initial N averages. When averaging is OFF, INIT:IMM sets the NPO flag to 1 each time a
measurement is completed. It acts as if the average count is set to 1. See "Synchronization" in the GPIB
Programmer's Guide for more information about the completion of averaged measurements.

ARM) in the Operation Status register.
Note
Trigger conditions must be met for each measurement—even when averaging is turned
on.
